|

## 1.4 为什么自建是个难题？
|
||||
## 1.4 Why is self-hosting a challenge?
|
||||
|
||||
要回答这个问题，就需要稍微多说一点背景信息了。
|
||||
To answer this question, we need to provide a little more background information.
|
||||
|
||||
一、科学上网这件事
|
||||
1. On the matter of accessing the internet through scientific means
|
||||
|
||||
科学上网这件事情，说来已经发展了近二十年（震惊!!!.jpg）。最初，自己稍微动动手即可（改改 host、连一下 ssh）、后来需要找一个网页代理，再后来需要写一个私有协议(比如 Shadowsocks)等等。
|
||||
The act of accessing the internet using scientific methods has been around for almost 20 years (shocking!!!.jpg). Initially, one could do it with a little effort (changing the host file, using SSH), then one had to find a web proxy, and later, one had to develop a private protocol (such as Shadowsocks) and so on.
|
||||
|
||||
随着 GFW 技术这十几年来不断的迭代升级，若要完成【自己动手科学上网】这个目标，需要做的事情已经包括但不限于：
|
||||
With the continuous iteration and upgrade of GFW technology over the past decade, to achieve the goal of [building your own scientific Internet access], the things that need to be done include but are not limited to:
|
||||
|
||||
- 了解 Linux 系统基本命令
|
||||
- 了解网络传输协议
|
||||
- 有技术和经济能力完成 VPS 购买及管理
|
||||
- 有技术和经济能力完成域名购买及管理
|
||||
- 有技术能力完成 TLS 证书申请 等等。
|
||||
- Understand basic Linux commands
|
||||
- Understand network transmission protocols
|
||||
- Have the technical and financial ability to purchase and manage a VPS
|
||||
- Have the technical and financial ability to purchase and manage a domain name
|
||||
- Have the technical ability to apply for a TLS certificate, and so on.
|
||||
|
||||
这就让【自建 VPS 科学上网】这个曾经简单的行为逐渐变成了令新人望而生畏的挑战。
|
||||
This has turned the once simple act of [setting up a self-built VPS for accessing the internet in a secure and unrestricted manner] into a daunting challenge that intimidates newcomers.
|
||||
|
||||
二、零基础用户的无奈
|
||||
2. Helplessness of Zero-based Users
|
||||
|
||||
零基础的非技术用户，如果完成上面这一连串的操作，势必要学习大量的知识，但稍微搜索之后，新人只怕会更加迷茫：大量的信息散布在互联网的各个角落：博客、问答网站、群组、论坛、GitHub、Telegram、YouTube 等等等等）。这些信息纷乱复杂、水平良莠不齐、甚至可能互相矛盾。基本上就是不把新人彻底弄晕誓不罢休。
|
||||
For non-technical users with zero foundation, if they complete the above series of operations, they will inevitably need to learn a lot of knowledge. However, after a little searching, newbies are likely to become even more confused: a large amount of information is scattered in various corners of the Internet: blogs, Q&A sites, groups, forums, GitHub, Telegram, YouTube, and so on. These pieces of information are chaotic and complex, with varying levels of quality, and may even contradict each other. Basically, they won't stop until they completely confuse the newcomer.
|
||||
|
||||
面对这些杂乱无章的信息，新人突然就从【信息匮乏】变成了【信息过剩】。若是几番连蒙带猜的折腾以失败告终（大概率如此）的话，他的积极性势必大受挫折。在这个过程中，若他又恰好去了一些不太友好的地方去求助，恐怕还要雪上加霜的被嘲讽一番：“这么菜，用机场不就行了，瞎折腾什么啊！”、“先去学会 Linux 再回来问吧”。
|
||||
Faced with such chaotic information, newcomers suddenly shift from [information scarcity] to [information overload]. If they fail after several attempts of groping and guessing (which is highly probable), their enthusiasm is bound to be greatly frustrated. In this process, if they happen to seek help in some unfriendly places, they may be ridiculed even more: "You're so inexperienced, just use the airport, why bother messing around!" "Go learn Linux first before coming back to ask."
|
||||
|
||||
这时候，大概也只有一声“呵呵”可以表达心情了。
|
||||
At this moment, probably only an "hehe" can express the mood.
|
||||
|
||||
## 1.5 “用机场不就行了？”
|
||||
## 1.5 "Why not just use the airport?"
|
||||
|
||||
首先，我想反问一下那些冷嘲热讽的人：“用机场”真的就是万灵药吗？
|
||||
First of all, I would like to respond to those who ridicule and criticize by asking a question: Is using the airport really a panacea?
|
||||
|
||||
其次，我认为“不懂”和“不想懂”是有本质区别的。态度恶劣的巨婴伸手党自然惹人厌烦，但真心自学却不得要领的人不该受到无端的白眼和歧视，也正是这种对新人不加区分的恶劣社区氛围促使我写下本文。那么闲话少说，我们来看看机场的优势与劣势究竟如何：
|
||||
Secondly, I believe that there is a fundamental difference between "not understanding" and "not wanting to understand". The bad attitude of some people who just want handouts is naturally annoying, but those who sincerely want to learn but don't know how should not be subject to unjustified contempt and discrimination. It is precisely this kind of bad community atmosphere that does not distinguish between newcomers that prompted me to write this article. So without further ado, let's take a look at the advantages and disadvantages of the airport:
|
||||
|
||||
一、“机场“的优势
|
||||
1. 稳定性高：机场节点数量多，分布广泛，避免了单点故障的风险，保证了整个网络的稳定性。
|
||||
2. 速度快：机场的节点通常采用高速服务器和优化的网络架构，网络速度较快，能够满足用户的高速上网需求。
|
||||
3. 安全性高：机场通常会采用严格的安全措施，如流量加密、防火墙等，保护用户数据的安全性。
|
||||
4. 稳定性高：机场通常采用专业的运维团队进行管理和维护，保证了服务的稳定性和可靠性。
|
||||
5. 服务质量高：机场通常会提供完善的客户服务，及时解决用户的问题和反馈，提升用户的满意度。
|
||||
|
||||
所谓“机场”，就是“线路提供商”。他负责完成 1.4 提到的那一串技术操作和管理，用户则付费获得使用权。所以，它的优点至少有：
|
||||
The so-called "airport" refers to the "line provider". They are responsible for completing the technical operations and management mentioned in section 1.4, while users pay for the right to use the service. Therefore, its advantages include at least:
|
||||
|
||||
1. **用户操作简单**：扫码操作、一键添加规则等
|
||||
2. **线路选择多**：可解锁不同国家、地区的网络服务；比如 iplc 等专线服务、游戏加速服务等
|
||||
3. **接入节点多**：所以抵抗节点封锁的能力强一些，封了一个就换下一个
|
||||
1. **Simple User Operation**: Scan code operation, one-click rule addition, etc.
|
||||
2. **Multiple Line Options**: Can unlock network services in different countries and regions, such as iplc dedicated line services, game acceleration services, etc.
|
||||
3. **Multiple Access Nodes**: Therefore, it has a stronger ability to resist node blocking, if one is blocked, just switch to another one.
|
||||
|
||||
二、“机场”的风险
|
||||
2. Risks of "Airport"
|
||||
|
||||
“方便”这枚硬币的另一面就是“风险”，基于“机场”的技术特点和市场情况，它的风险至少有：
|
||||
"The other side of the coin of 'convenience' is 'risk'. Based on the technical characteristics and market conditions of the 'airport', its risks include at least:"
|
||||
|
||||
1. **“机场”可完全获得用户信息**：用户在网上的所有痕迹，都【必然】经过且【非常可能】长期存储在其服务器上，这些记录无法受到任何具备法律效力的用户隐私协议的约束（**窥视、记录你的一举一动**）
|
||||
2. **“机场”缺乏市场管理**：不可避免存在着以欺诈为目标的恶意商家（**主动跑路**）
|
||||
3. **“机场”面临监管压力**：大机场相对有保障的同时，也无法避免树大招风。2020 年间，已经有几个大机场停运、跑路的事件发生，用户的正常使用受到严重干扰（**被动跑路**）
|
||||
4. **“机场”技术水平难以确定**：线路质量良莠不齐，挂羊头卖狗肉的现象屡见不鲜（**速度慢、掉线多、连不上**）
|
||||
1. "Airport" can fully obtain user information: All the traces left by users online will inevitably and very likely be stored on their servers for a long time. These records cannot be restricted by any legally binding user privacy agreement. ("Snooping and recording your every move")
|
||||
2. "Airport" lacks market management: There are inevitably malicious merchants who target fraud. ("Actively run away")
|
||||
3. "Airport" faces regulatory pressure: While large airports are relatively secure, they cannot avoid attracting attention. In 2020, several large airports experienced shutdowns and runaways, seriously disrupting users' normal usage. ("Passively run away")
|
||||
4. "Airport" technical level is difficult to determine: The quality of the line varies greatly, and the phenomenon of falsely advertising quality services is common. ("Slow speed, frequent disconnections, unable to connect")
|
||||
|
||||
## 1.6 那么你到底要不要自建呢？
|
||||
## 1.6 So should you build your own website?
|
||||
|
||||
现在，你已经看到了机场的优势和风险，要用什么，就请各位充分思考并自行决定。毕竟，最适合你的方案才是最好的方案。
|
||||
Now that you have seen the advantages and risks of the airport, please think carefully and make your own decision on what to use. After all, the best plan is the one that suits you best.
|
||||
|
||||
|
||||
|
||||
1. 如果决定使用机场的话，现在，你可以关闭本文了。
|
||||
1. If you decide to use the airport, you can close this article now.
|
||||
|
||||
2. 如果你决定自建，那就请继续阅读后面的章节吧！！
|
||||
2. If you decide to build it yourself, please continue reading the following chapters!
|
||||
|
||||
总之，本文的目标就是成为零基础用户的知识起点，提供对每一步充分的讲解和演示，清清楚楚（甚至**婆婆妈妈、絮絮叨叨、啰啰嗦嗦**）的协助新人完成【**从输入第一条命令开始，完成 VPS 服务器部署，并成功在客户端完成科学上网**】的全程。并在这个过程中帮助新人逐步接触和熟悉 Linux 的基础操作，为之后的进一步自学打下基础。
|
||||
In short, the goal of this article is to serve as a starting point for users with zero experience, providing thorough explanations and demonstrations for each step, even if it may seem overly detailed or repetitive. The aim is to assist beginners in completing the entire process of deploying a VPS server from the first command input to successfully accessing the internet via the client, and gradually introducing them to basic Linux operations, laying a foundation for further self-learning.
|
||||
|
||||
## 1.7 题外啰嗦几句
|
||||
## 1.7 Some digressions
|
||||
|
||||
1. 墙外的信息泥沙俱下，请务必学会理性、独立的思辨，不要随意站队，不要轻信猎奇的信息。
|
||||
1. There is a wealth of information outside of the wall, so please learn to think rationally and independently. Don't take sides easily and don't believe in sensational information.
|
||||
|
||||
2. 衷心希望大家获得更顺畅的网络后，可以获取更新鲜的知识、更丰富的娱乐、接触更美好的世界、结交更多志同道合的朋友，但不要成为任何有不可告人目的之人的替罪羊。
|
||||
2. We sincerely hope that with a smoother internet, everyone can access fresher knowledge, richer entertainment, experience a better world, and make more like-minded friends, but do not become a scapegoat for anyone with ulterior motives.
|
||||
|
||||
3. 你的互联网身份依然是你的身份，绝对的匿名化是极为困难的，所以请务必遵守你个人所在地区和 IP 所在地区的相关法律法规。无论何时，自我保护都是最基本的底线。
|
||||
3. Your internet identity is still your identity, and achieving absolute anonymity is extremely difficult. Therefore, please be sure to comply with the relevant laws and regulations in your personal location and the location of your IP address. Self-protection is always the most basic bottom line.

## 2.1 Acquiring a VPS
|
||||
|
||||
你需要获取一台健康的、IP 没有被墙的 VPS，并在管理后台做下面这些基础准备：
|
||||
You need to obtain a healthy VPS with an unblocked IP, and perform the following basic preparations in the management console:
|
||||
|
||||
1. 在 VPS 的后台安装 Debian 10 64bit 系统
|
||||
2. 小本本记下 VPS 的 IP 地址（本文会用 `"100.200.300.400"` 来表示）
|
||||

|
||||
:::
|
||||
3. 小本本记下 VPS 的 SSH 远程登陆端口(Port)
|
||||
4. 小本本记下 SSH 远程登录的用户名和密码
|
||||
1. Install Debian 10 64-bit system in the backend of VPS.
|
||||
2. Write down the IP address of VPS in a notebook (this article will use `"100.200.300.400"` as an example, which is an intentionally incorrect and illegal IP address. Please replace it with your real IP address).
|
||||
3. Write down the SSH remote login port of VPS in a notebook.
|
||||
4. Write down the username and password for SSH remote login in a notebook.
|
||||
|
||||
购买 VPS 是一个比较复杂的事情，建议先去学习一下相关知识，选择适合自己的经济能力和线路需求的即可。另外可以选择薅一些国际大厂的羊毛（比如甲骨文和谷歌提供的永久免费或限时免费的套餐）。总之，务必量力而行。
|
||||
Buying a VPS is a relatively complex matter. It is recommended to first learn the relevant knowledge and choose one that suits your own economic ability and line requirements. In addition, you can choose to take advantage of some benefits offered by international giants (such as permanent free or limited-time free packages offered by Oracle and Google). In any case, you must act within your means.

关于选择 Debian 10 作为操作系统，这里稍微多说一句：不管你在网上听说了什么，不管哪个大神告诉你 XXX 版的 Linux 更好、XXX 版的 Linux 更牛，这些 Linux 的派系之争**跟现在的你半毛钱关系也没有**！使用 Debian 10 足以让你的 VPS 服务器在安全、稳健运行的同时得到足够的优化（如 cloud 专用内核、及时的 bbr 支持等）。等你对 Linux 熟悉之后，再回头去尝试其他的 Linux 发行版也不迟。
|
||||
:::tip Explanation
|
||||
Regarding the choice of Debian 10 as the operating system, let me elaborate a bit: No matter what you have heard online, no matter which guru has told you that XXX version of Linux is better or XXX version of Linux is more powerful, these sectarian disputes have **nothing to do with you right now**! Using Debian 10 is enough to optimize your VPS server for security, stability, and performance (such as using cloud-optimized kernel, timely support of BBR, etc.). After you become familiar with Linux, you can try other Linux distributions.

## 2.2 Obtaining a Desired Domain Name
|
||||
|
||||
你需要获取一个域名、并在 DNS 设置中添加一条 A 记录，指向你 VPS 的 IP 地址
|
||||
You need to obtain a domain name and add an A record in the DNS settings, pointing to the IP address of your VPS.
|
||||
|
||||
1. 请选择靠谱的国际域名服务商。选择一些常见的域名后缀就行，注意不要用 `.cn` 后缀。
|
||||
2. 在 DNS 设置中，添加一条指向你 VPS 的 IP 地址的 A 记录（A 记录的名字可以随便起，本文会用 `"a-name"` 来表示。完整的域名则会用 `"二级域名.你的域名.com"` 或者 `"a-name.yourdomain.com"` 来表示）。效果如下图：
|
||||
1. Please choose a reliable international domain name service provider. Choose some common domain name suffixes, and make sure not to use the `.cn` suffix.
|
||||
2. In the DNS settings, add an A record pointing to the IP address of your VPS (the name of the A record can be anything, and in this article, it will be represented by `"a-name"`). The complete domain name will be represented by `"subdomain.yourdomain.com"` or `"a-name.yourdomain.com"`. The effect is as shown in the picture below:

# 【第 3 章】远程登录篇
|
||||
# [Chapter 3] Remote Login
|
||||
|
||||
## 3.1 远程登录 VPS (PuTTY)
|
||||
## 3.1 Remote Login to VPS (PuTTY)
|
||||
|
||||
首先，鉴于零基础人群中 Windows 的用户基数最大，所以本文以 Windows 为例进行展示。
|
||||
First of all, considering that the user base of Windows is the largest among the zero-based population, this article uses Windows as an example for demonstration.
|
||||
|
||||
其次，虽然 Windows 10 之后的 PowerShell 和 WSL 也可以达到很好的 SSH 操作体验。但是因为并非所有版本的 Windows 都有最新的组件，故本文还是以老牌的 PuTTY 为例，进行 SSH 远程登录的操作详解。（使用其他工具的话、在 SSH 登陆之后的操作都是一样的）
|
||||
Secondly, although PowerShell and WSL after Windows 10 can also achieve a good SSH operation experience, not all versions of Windows have the latest components. Therefore, this article uses the classic PuTTY as an example to provide a detailed explanation of SSH remote login operation. (If you use other tools, the operations after the SSH login are the same.)
|
||||
|
||||
下面就跟我一步步操作吧。
|
||||
Follow me step by step and let's start the operation.
|
||||
|
||||
1. 进入 PuTTY 的[官网](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)，选择适合你操作系统的版本下载。（本文以 64 位版本为例）
|
||||
1. Go to the [official website](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html) of PuTTY and download the version that suits your operating system (this article uses the 64-bit version as an example).
|
||||
|
||||
|
||||
|
||||
|
||||
2. 安装运行后，将会看到 PuTTY 的主界面。现在请拿出你上一章记东西的[小本本](./ch02-preparation.md#21-%E8%8E%B7%E5%8F%96%E4%B8%80%E5%8F%B0vps)，在下图的对应位置填入你 VPS 的**IP 地址(VPS IP)**和**端口(VPS PORT)**。为了方便以后使用时不用重复输入，我们可以保存会话 (Saved Sessions)，未来使用时只要按 Load 即可一键载入设置。
|
||||
2. After installation and running, you will see the main interface of PuTTY. Now please take out your notebook from the previous chapter where you wrote down the **IP address (VPS IP)** and **port (VPS PORT)** of your VPS in the corresponding positions of the following figure. In order to save time and avoid repeatedly entering these details in the future, we can save the session (Saved Sessions), and simply load it in the future with one click.
|
||||
|
||||
|
||||
|
||||
|
||||
3. 我建议将 `Connection` 中的 `keepalive` 设置为 `60` 秒，防止你一段时间没有操作之后 SSH 自动断线。另外务必再次保存设置。
|
||||
3. I suggest setting `keepalive` to `60` seconds in the `Connection` to prevent SSH from automatically disconnecting after a period of inactivity. Be sure to save the settings again.
|
||||
|
||||
|
||||
|
||||
|
||||
::: warning 注意
|
||||
对 PuTTY 的任何设置更新都要再次手动保存 Session，不然关闭后就会丢失
|
||||
::: warning Attention
|
||||
Any update to the PuTTY configuration needs to be manually saved to the session again. Otherwise, it will be lost after closing.
|
||||
:::
|
||||
|
||||
4. 点击 Open 就会进入 SSH 连接窗口，对应下图输入用户名与密码，与你的 VPS 远程主机建立连接。（本文假设默认用户名是 `root`，另外，在 Linux 系统输入密码的时候，是不会出现 `******` 这种提示符的，这样可以避免密码长度泄漏，不是你的键盘坏掉了哦！）
|
||||
4. Click on Open to enter the SSH connection window, then enter the username and password corresponding to the following figure to establish a connection with your VPS remote host. (This article assumes that the default username is `root`. Also, when entering a password in the Linux system, there will be no prompt like `******`, which can avoid password length leakage. It's not that your keyboard is broken!)

## 3.2 成功登录 SSH！初识命令行界面！
|
||||
## 3.2 Successfully Logging in SSH! Introduction to Command Line Interface!
|
||||
|
||||
1. 如果你的信息都填写正确，你将会看到类似下图的界面，说明已登录成功：
|
||||
1. If you have filled in your information correctly, you will see a similar interface as the picture below, indicating that you have successfully logged in:
|
||||
|
||||
|
||||
|
||||
|
||||
这个界面，就等于远程服务器的【桌面】，但它没有你熟悉的图标和鼠标，没有绚丽的色彩，有的只是简单文字，这就是【**命令行界面**】- `Command Line Interface`，或者缩写为 `CLI`。
|
||||
This interface is equivalent to the "desktop" of a remote server, but it does not have familiar icons and a mouse, nor does it have colorful graphics. Instead, all you see is simple text. This is the "**Command Line Interface**" - shortened as `CLI`.
|
||||
|
||||
接下来的所有操作，都需要你像电影里的黑客一样，在这个命令行界面中完成。也许你会觉得陌生，但请相信我，使用命令行既不可怕，也不神秘。说到底，它只不过是把你习惯的鼠标操作变成了文字指令而已，**你说一句，它做一句**。
|
||||
All the following operations require you to act like a hacker in a movie and complete them in this command-line interface. Maybe you will feel unfamiliar, but please believe me, using the command-line interface is neither scary nor mysterious. In the end, it just turns your familiar mouse operations into textual commands, **you say it, it does it**.
|
||||
|
||||
2. 现在，你可以稍微观察并熟悉一下命令行环境，这个界面其实已经告诉了你一些有用的信息了，比如系统内核版本（比如图内是 `4.19.37-5`）、上次登录时间及 IP 等。当然根据 VPS 的不同，你看到的界面可能会略有不同。
|
||||
2. Now, you can observe and familiarize yourself with the command line environment a little bit. This interface has actually provided you with some useful information, such as the system kernel version (e.g. `4.19.37-5` in the picture), last login time and IP address. Of course, depending on the VPS, the interface you see may be slightly different.
|
||||
|
||||
3. 请注意命令行最下面一行，闪动的光标左边，有一串字符。图中显示的是`root@vps-server:~#`，这一串要怎么理解呢？很简单：
|
||||
3. Please pay attention to the line at the bottom of the command line, to the left of the flashing cursor, there is a string of characters. The one shown in the figure is `root@vps-server:~#`. How to understand this string? It's very simple:
|
||||
|
||||
- 现在的用户是 `root`
|
||||
- `root` 所在的服务器是 `vps-server`
|
||||
- `root` 现在所在的文件夹是 `~`
|
||||
- `#` 之后是你可以输入命令的地方
|
||||
- The current user is `root`
|
||||
- The server where `root` is located is `vps-server`
|
||||
- The current directory where `root` is located is `~`
|
||||
- After `#` is the place where you can input commands.
|
||||
|
||||
前两个很直观，无需多说。第三个是关于 Linux 的文件夹系统，现在也不需要过于深入，你只需要知道，"`~`"就是【当前用户的大本营】。第四个，提示符`#`，你也不用管，只需要知道，未来文章中会写一些需要你输入的命令，都会以 "`#`" 或者 "`$`" 开头，提示你**后面**是你输入命令的地方。（所以你复制命令的时候，**只需要复制后面的内容**，不要复制提示符）
|
||||
The first two are pretty straightforward, no need to explain further. The third one is about the folder system in Linux. You don't need to go too deep into it for now. Just know that "`~`" represents **the home directory of the current user**. As for the fourth one, the prompt symbol "`#`", you don't need to worry about it either. Just know that in future articles, there will be some commands that you need to input, and they will be preceded by "`#`" or "`$`" to indicate **where you should input the command**. (So when you copy the command, **just copy the content after the prompt symbol** and don't copy the prompt symbol itself.)
|
||||
|
||||
## 3.3 第一次更新 Linux 的软件！
|
||||
## 3.3 Updating software on Linux for the first time!
|
||||
|
||||
1. 正如你的手机，无论安卓还是 iPhone，为了 APP 及时更新（获取安全补丁和新功能），都会时不时从应用商店获得更新信息，并且提示你有多少个 APP 可更新。Linux 系统也有逻辑十分类似的更新机制。所以只要你会更新手机 APP，就能学会更新 Linux 软件！
|
||||
1. Just like your phone, whether it's Android or iPhone, in order to keep your apps up-to-date (to get security patches and new features), you will occasionally receive update notifications from the app store, telling you how many apps need to be updated. Linux systems also have a similar update mechanism that works logically. So as long as you know how to update phone apps, you can learn how to update Linux software!
|
||||
|
||||
2. Linux 下，每个 APP 都叫做一个“包” （package）。管理 APP 的程序自然就叫做“包管理器”（Package Manager）。你可以通过它安装、更新、卸载各种软件、甚至更新 Linux 系统本身。Linux 下的包管理器非常强大，此处按下不表，现在你只需要知道 Debian 系统的包管理器叫做 `apt` 即可。接下来，我们就先使用 `apt` 做一次软件的全面更新，让你熟悉它的基本操作。
|
||||
2. In Linux, each application is called a "package". The program that manages the applications is naturally called a "package manager". You can use it to install, update, and uninstall various software, and even update the Linux system itself. Package managers in Linux are very powerful, but we won't go into details here. For now, you only need to know that the package manager for the Debian system is called `apt`. Next, we will first use `apt` to do a comprehensive update of the software to familiarize you with its basic operations.

||||
3. 小小白白 Linux 基础命令：

||||
| `cmd-01` | `apt update` | Query software updates |
|
||||
| `cmd-02` | `apt upgrade` | Perform software updates |
|
||||
|
||||
4. 现在请输入第一条命令，获取更新信息
|
||||
4. Now, please enter the first command to get update information.
|
||||
|
||||
```shell
|
||||
apt update
|
||||
```
|
||||
```shell
|
||||
apt update
|
||||
```
|
||||
|
||||
5. 然后请输入第二条命令，并在询问是否继续安装 `(Y/n)` 时输入 `y` 并回车确认，开始安装
|
||||
This is a command used in a Linux terminal to update the package list from the repositories configured on the system.
|
||||
|
||||
```shell
|
||||
apt upgrade
|
||||
```
|
||||
5. Then enter the second command, and when asked if you want to continue installing `(Y/n)`, type `y` and press enter to confirm and start the installation.
|
||||
|
||||
6. 完整流程演示如下：
|
||||
```shell
|
||||
apt upgrade
|
||||
```
|
||||
|

# 【第 4 章】安全防护篇
|
||||
# [Chapter 4] Security and Protection
|
||||
|
||||
## 4.1 为什么要做安全防护
|
||||
## 4.1 Why Do We Need Security Protection?
|
||||
|
||||
Linux 服务器的安全防护是一个纷繁复杂的巨大课题。无数的网站、APP、服务、甚至线下基础设施都建立在 Linux 的基石之上，这背后牵涉到巨大的经济利益和商业价值，当然也就就意味着黑灰产有巨大的攻击动力。但是这些服务是如此重要、根本不允许出现重大的安全漏洞。于是无数的运维专业人员都在安全攻防的战场上拼搏努力，这才让大家能享受到基本稳定的现代化数字生活。
|
||||
Security protection for Linux servers is a complex and huge subject. Countless websites, apps, services, and even offline infrastructure are built on the foundation of Linux, which involves huge economic benefits and commercial value. This also means that there is a huge motivation for black and gray industries to launch attacks. However, these services are so important that major security vulnerabilities are not allowed. Therefore, countless operation and maintenance professionals are working hard on the battlefield of security attacks and defense, which enables us to enjoy a basic stable modern digital life.
|
||||
|
||||
现在，你拥有了一台 VPS，并且将会敞开他的数据访问渠道来达到流量转发的目标，那就相当于你已经置身于安全攻防战场的第一线、直面所有风险。但与此同时，新人由于知识和信息的不足，看待安全问题是总是难免两极分化：要么觉得轻如鸿毛和自己没有半点关系，要么觉得重于泰山甚至惶惶不可终日。
|
||||
Now, you have a VPS and will open its data access channel to achieve the goal of traffic forwarding, which means you are now on the front line of the security battle and face all risks. However, at the same time, newcomers tend to have a polarized view of security issues due to lack of knowledge and information: either they feel it is as light as a feather and has nothing to do with them, or they feel it is as heavy as Mount Tai and feel anxious all day long.
|
||||
|
||||
- 对于前者，我的建议是：安全无小事，尽量多查一些安全方面的信息，免得自己真的受了损失才后悔莫及
|
||||
- For the former, my suggestion is: safety is of utmost importance. Try to gather more information on safety issues to avoid regretting after experiencing losses.
|
||||
|
||||
- 对于后者，我的建议是：不用紧张，我们的服务器仍不具有太高的价值、一般不会吸引到高水平的攻击，需要面对的基本都是一些自动化脚本的恶意扫描和登录尝试，跟着本文做一些基础的防护即可
|
||||
- For the latter, my suggestion is: don't worry too much, our servers still don't have too much value and generally won't attract high-level attacks. The basic threats we need to face are mostly malicious scans and login attempts from some automated scripts. Just follow this article to do some basic protection.
|
||||
|
||||
## 4.2 具体的风险到底是什么
|
||||
## 4.2 What are the specific risks
|
||||
|
||||
就像我们在《远程登录篇》配置的一样，任何人只需要知道【IP 地址】+【端口】+【用户名】+【密码】这四个要素，就能登录你的 VPS 服务器。那很显然，这四要素的安全就是我们要防护的底线。我们来逐一分析：
|
||||
Just like the configuration we did in the "Remote Login" section, anyone who knows the four elements of [IP address] + [port] + [username] + [password] can log in to your VPS server. So obviously, the security of these four elements is the bottom line that we need to protect. Let's analyze them one by one:
|
||||
|
||||
1. 【IP 地址】：恶意脚本会随机尝试和扫描 IP 段，可以简单认为是公开信息、无法隐藏
|
||||
1. [IP Address]: Malicious scripts randomly attempt to scan IP ranges, which can be regarded as public information and cannot be hidden.
|
||||
|
||||
2. 【端口】：如果使用默认端口，那么【端口 = `22`】
|
||||
2. [Port]: If you are using the default port, then [Port = `22`].
|
||||
|
||||
3. 【用户名】：如果使用默认用户，那么【用户名 = `root`】
|
||||
3. [Username]: If using the default user, then [Username = `root`]
|
||||
|
||||
4. 【密码】：密码不存在默认值，一定是由 VPS 后台随机生成或由你自行设置的。也就是说，如果你的服务器都是默认设置，则四要素中的三个已经是已知的，那么你整个服务器的安全，就全部寄托在一串小小的密码上了。这时有几种情况：
|
||||
4. [Password]: There is no default value for the password. It must be randomly generated by the VPS backend or set by you. In other words, if all the settings of your server are default, then three of the four elements are already known. Therefore, the security of your entire server relies on a small password. In this case, there are several situations:
|
||||
|
||||
- 如果你用了 VPS 管理后台随机生成密码，它一般包含随机的十几个大小写混杂的字母和符号，相对比较安全
|
||||
- If you use a VPS management background to generate passwords randomly, it usually contains random uppercase and lowercase letters, symbols, and is relatively secure.
|
||||
|
||||
- 如果你为了好记、把密码改成了类似`123456`这种超弱的密码，破解你的 VPS 服务器可谓不费吹灰之力
|
||||
- If you changed your password to something super weak like `123456` just for the sake of easy memorization, hacking into your VPS server would be a piece of cake.
|
||||
|
||||
- 如果你为了好记、把密码改成了比较复杂、但在别的地方用过的密码，其实也并不安全。你要明白黑客手里有作弊器，比如说`密码表`，包含数万、数十万、数百万甚至更多曾经泄漏的真实密码）
|
||||
- If you change your password to a more complex one that you have used elsewhere just for the sake of easy memory, it is not really safe. You should understand that hackers have cheats in their hands, such as `password tables`, which contain tens of thousands, hundreds of thousands, millions, or even more real leaked passwords.
|
||||
|
||||
5. 但你要明白，没有哪个黑客真的要坐在电脑前一次一次的尝试你的密码，全部的攻击尝试都是恶意脚本自动进行的，它会 24 小时不眠不休的工作。也许每天你酣睡之时，你的服务器都在经受着一轮又一轮的冲击。
|
||||
5. But you should understand that no hacker really sits in front of a computer and tries your password repeatedly. All attack attempts are carried out automatically by malicious scripts, which work tirelessly for 24 hours. Perhaps while you are sleeping soundly every night, your server is enduring round after round of attacks.
|
||||
|
||||
一旦密码被成功撞破，意味着你的四要素全部被攻击者掌握，恶意脚本就会快速登录服务器、获取服务器的最高 `root` 控制权、安装部署它的恶意服务，然后就可以用你的服务器来 24 小时做各种坏事（比如挖矿、传播病毒、发送垃圾邮件、欺诈邮件、做 BT 中继、甚至暗网公众节点等等等等）。如果恶意脚本比较克制，其实可以做到相当的隐蔽性。而新人一般也不会去观察留意 VPS 的登录记录、进程变化、CPU 占用变化、流量变化等指标，你其实就很难发现自己被黑了。直到你的 VPS 服务商封禁你的账号、或者收到律师函为止。
|
||||
Once the password is successfully cracked, it means that all four of your elements have been mastered by the attacker. The malicious script will quickly log in to the server, obtain the highest `root` control of the server, install and deploy its malicious services, and then use your server to do all kinds of bad things 24 hours a day (such as mining, spreading viruses, sending spam emails, fraudulent emails, acting as a BT relay, and even dark web public nodes, and so on). If the malicious script is relatively restrained, it can actually achieve considerable concealment. Generally, newcomers will not observe and pay attention to indicators such as login records, process changes, CPU usage changes, and traffic changes of the VPS, so it is difficult for you to discover that you have been hacked. Until your VPS service provider blocks your account or you receive a lawyer's letter.
|
||||
|
||||
6. 别忘了，你获得 VPS 时大概率需要使用真实的支付信息，你登录各种网站、社交平台时也会留下你的 IP 地址，这些都与你的身份有直接或者间接的关系。于是，**一旦这些坏事发生，它们就不可避免的与你产生了关联。**
|
||||
6. Don't forget that when you obtain a VPS, you probably need to use your real payment information, and when you log in to various websites and social platforms, your IP address will also be recorded, which has a direct or indirect relationship with your identity. Therefore, once these bad things happen, they will inevitably be associated with you.
|
||||
|
||||
## 4.3 我们要做的安全防护有哪些
|
||||
## 4.3 What security measures do we need to take
|
||||
|
||||
基于上述分析，我们要做的，自然就是对【端口】、【用户名】、【密码】这三要素进行加强，来降低被攻破的风险：
|
||||
Based on the above analysis, what we need to do is to strengthen the three elements of [port], [username], and [password] to reduce the risk of being hacked.
|
||||
|
||||
1. 【端口】：将 SSH 远程登录端口修改为【非 22 端口】 （4.4）
|
||||
2. 【用户名】：建立【非 root】的新用户、并禁用 root 用户 SSH 远程登录 （4.5、4.6）
|
||||
3. 【密码】：SSH 启用 RSA 密钥验证登录、同时禁用密码验证登录 （4.7）
|
||||
1. [Port]: Modify the SSH remote login port to a [non-22 port] (4.4).
|
||||
2. [Username]: Create a [non-root] new user and disable root user SSH remote login (4.5, 4.6).
|
||||
3. [Password]: Enable RSA key verification for SSH login and disable password verification login (4.7).
|
||||
|
||||
记得按顺序来，别把自己锁在门外了。
|
||||
Remember to follow the order and don't lock yourself out.
|
||||
|
||||
## 4.4 将 SSH 远程登录端口修改为非 22 端口
|
||||
## 4.4 Change the SSH Remote Login Port to a Non-22 Port
|
||||
|
||||
现在，我们来解决【端口 = `22`】的问题。（注意：有些 VPS 服务商，默认的端口已经是非 22 端口，那么你可以忽略这一步，当然也可以跟着本文改成别的端口）
|
||||
Now, let's solve the problem of "port = `22`". (Note: some VPS service providers have non-22 ports set as default, so you can ignore this step if that's the case. Of course, you can also follow this article to change it to another port.)

1. 小小白白 Linux 基础命令：
|
||||
1. Basic commands of Little White Linux:
|
||||
|
||||
| 编号 | 命令名称 | 命令说明 |
|
||||
| :------: | :-----------------: | :----------: |
|
||||
| `cmd-03` | `nano` | 文本编辑器 |
|
||||
| `cmd-04` | `systemctl restart` | 重启某个服务 |
|
||||
| ID | Command Name | Description |
|
||||
| :------: | :-----------------: | :---------------: |
|
||||
| `cmd-03` | `nano` | Text editor |
|
||||
| `cmd-04` | `systemctl restart` | Restart a service |
|
||||
|
||||
2. 小小白白 Linux 基础配置文件
|
||||
2. Basic Configuration Files of Little White Linux
|
||||
|
||||
| 编号 | 配置文件位置 | 文件说明 |
|
||||
| :-------: | :--------------------: | :------------------: |
|
||||
| `conf-01` | `/etc/ssh/sshd_config` | SSH 远程登录程序设置 |
|
||||
| Number | Configuration File Location | File Description |
|
||||
| :-------: | :-------------------------: | :-------------------------------: |
|
||||
| `conf-01` | `/etc/ssh/sshd_config` | SSH Remote Login Program Settings |
|
||||
|
||||
3. 我们要做的第一件事，当然就是【用`nano`这个文本编辑器打开`SSH远程登录程序设置`】，在 Windows 下，你会【找到文件并双击】，在 Linux 下该怎么办呢？仔细看看上面的命令说明，是不是就很简单了？没错，就是：
|
||||
3. The first thing we need to do, of course, is to [open the SSH remote login program settings with the text editor `nano`]. In Windows, you will [find the file and double-click] it. What should you do in Linux? Take a close look at the command instructions above, isn't it simple? Yes, it is:
|
||||
|
||||
```shell
|
||||
nano /etc/ssh/sshd_config
|
||||
```
|
||||
```shell
|
||||
nano /etc/ssh/sshd_config
|
||||
```
|
||||
|
||||
4. 文件打开后，你就进入了`nano`的界面，稍微观察一下，你会发现，它把重要的快捷键都显示在屏幕下方了（下图红框内），直接开卷考试、不用死记硬背，是不是很贴心呢？
|
||||
This is a command in the shell terminal to open the `sshd_config` file located in the `/etc/ssh/` directory using the `nano` text editor.
|
||||
|
||||
|
||||
4. Once the file is opened, you will enter the interface of `nano`. After observing for a while, you will find that it displays important shortcut keys at the bottom of the screen (enclosed in a red box in the figure below). You can take the exam directly without memorizing them, which is very user-friendly, isn't it?
|
||||
|
||||
5) 我们要做的第二件事，是【在打开的文件中找到`Port`这一项，并修改它的端口】。Port 后面的数字就是 SSH 的端口，一般建议把它改成一个大于`1024`小于`65535`的整数（本文以`9753`为例）。请结合`nano`的快捷键，想一下该怎么操作呢？果然，你又说对了！就是：
|
||||
|
||||
|
||||
- 使用 `ctrl+w` 进入搜索模式，然后输入 `Port 22` 并回车
|
||||
- 删除 `22` 并改成 `9753`
|
||||
- 说明：如果这一行开头有个`#`，证明这一行【不生效】（被注释掉了），你可像我一样在文件最后写一个不带`#`的，或者把`#`删掉就好。
|
||||
5) The second thing we need to do is to **find the `Port` item in the opened file and modify its port**. The number after `Port` is the SSH port. It is generally recommended to change it to an integer greater than `1024` and less than `65535` (this article takes `9753` as an example). Please think about how to operate it with the shortcut keys of `nano`. You are right again! It is:
|
||||
|
||||
::: warning
|
||||
本文以`9753`为例，就意味着随着本文的发布，这个端口会变成一个不大不小的特征，也许会被攻击者优先尝试、也许被 GFW 干扰、阻断。所以我强烈建议你用一个自己想到的其他端口，毕竟，你有 6 万多个端口可以自由选择。
|
||||
:::
|
||||
|
||||
6. 我们要做的第三件事，是【保存文件并退出】
|
||||
|
||||
- 如果第 3 步你有仔细观察，就会发现保存并不是常见的 `ctrl+s`。
|
||||
- 正确的快捷键：保存是 `ctrl+o` + `回车`，退出是 `ctrl+x`
|
||||
|
||||
7. 我们最后要做的事，是【重启 ssh 服务，使变更生效】
|
||||
|
||||
```shell
|
||||
systemctl restart ssh
|
||||
```
|
||||
|
||||
8. 完整流程演示如下：
|
||||
|
||||
|
||||
|
||||
9. 修改 PuTTY 配置
|
||||
|
||||
现在新的端口已经生效，下次使用 PuTTY 登录时就要用`9753`了。所以现在请到 PuTTY 的设置中修改端口号码，然后保存 Session。嗯，你应该知道去哪里改了吧？（如果不知道的话，要重读前面的内容了哦！）
|
||||
|
||||
## 4.5 建立非 root 的新用户
|
||||
|
||||
第二步，我们来解决【用户名 = `root`】的问题。
|
||||
|
||||
首先你要理解， Linux 系统中的`root`，不仅仅是一个管理员账号那么简单。它是整个系统的【根基】、是系统的主宰、至高无上的神。一旦`root`账号出现安全问题，整个系统都只能任人鱼肉、无处可逃。那么就跟随我进行操作吧：
|
||||
|
||||
1. 小小白白 Linux 基础命令：
|
||||
|
||||
| 编号 | 命令名称 | 命令说明 |
|
||||
| :------: | :-----------: | :--------------------------: |
|
||||
| `cmd-05` | `adduser` | 给系统新增用户 |
|
||||
| `cmd-06` | `apt install` | 安装某个软件 |
|
||||
| `cmd-07` | `visudo` | 修改 sudo 权限设置专用编辑器 |
|
||||
|
||||
2. 我们要做的第一件事，是【新增一个用户并设定登录密码】，名字你可以随便起，我这里以`vpsadmin`为例：
|
||||
|
||||
```shell
|
||||
adduser vpsadmin
|
||||
```
|
||||
|
||||
执行命令后，根据提示操作即可。请务必设置一个用户密码（别忘记设置密码时你时看不到 `******` 的）。之后系统会询问你一些用户的附加信息，这些就可以无视，一路回车即可。
|
||||
|
||||
|
||||
|
||||
::: warning
|
||||
本文以`vpsadmin`为例，就意味着随着本文的发布，这个用户名也会变成一个不大不小的特征，也许会被攻击者优先尝试。所以和端口一样，我强烈建议你用一个自己想到的其他用户名。
|
||||
:::
|
||||
|
||||
3. 完整流程演示如下：
|
||||
|
||||
|
||||
|
||||
4. 我们要做的第二件事，是【安装`sudo`功能】（`sudo` 就是在关键时刻，让普通账户临时获得 `root` 的神力，战力全开拯救世界）
|
||||
|
||||
```shell
|
||||
apt update && apt install sudo
|
||||
```
|
||||
|
||||
聪明的你大概已经发现，这一行命令其实是两个命令。前一半 `apt update` 你之前已经见过并且用过了，是去服务器刷新软件版本信息。后面的 `apt install`
|
||||
就是这一次要用到的【安装命令】。两条连接在一起，就是让系统去【刷新可用的最新软件，然后安装最新版的`sudo`程序】。 `&&` 则是把两个命令连起来执行的意思。
|
||||
|
||||
5. 我们要做的第三件事，是【把`vpsadmin`用户加入`sudo`名单里，让他有资格借用`root`的神力】
|
||||
|
||||
```shell
|
||||
visudo
|
||||
```
|
||||
|
||||
在 `User Privilege Specification` 下加入一行 `vpsadmin ALL=(ALL) NOPASSWD: ALL` 即可。
|
||||
|
||||
::: warning
|
||||
我要特别说明的是`NOPASSWD`这个设置，它的意思是`vpsadmin`用户临时使用`root`权限时，不用额外输入密码。**这与一般的安全建议相反**。我之所以如此推荐，是因为很多新人不顾危险坚持使用`root`账号就是因为用`root`时不用重复输入密码、觉得轻松。“两害相权取其轻”，我认为【直接用`root`用户的风险】大于【使用`sudo`
|
||||
时不用输密码的风险】，所以做了以上的建议。
|
||||
|
||||
如果你希望遵守传统习惯、每次使用`sudo`时需要输入密码，那么这一行改成 `vpsadmin ALL=(ALL:ALL) ALL` 即可。

|
||||
## 4.6 禁用 root 用户 SSH 远程登录
|
||||
|
||||
1. 现在你已经逐渐熟悉 Linux 了，所以这次换你思考，我们要做的第一件事是什么呢？没错，还是【用`nano`编辑器打开`SSH远程登录程序设置`】，什么，你想不起来怎么操作了？那去复习一下上面的内容再回来吧！............ 正确答案：
|
||||
|
||||
```shell
|
||||
nano /etc/ssh/sshd_config
|
||||
```
|
||||
|
||||
2. 找到`PermitRootLogin Yes`这一项，然后把它后面的设定值改为`no`即可。还记得怎么操作吗？............ 正确答案：
|
||||
|
||||
- 使用 `ctrl+w` 进入搜索模式，然后输入 `PermitRootLogin` 并回车
|
||||
- 删除 `yes` 并改成 `no`
|
||||
|
||||
3. 保存文件并退出。还记得怎么操作吗？............ 正确答案：
|
||||
|
||||
- 保存是 `ctrl+o`，然后 `回车` 确认
|
||||
- 退出是 `ctrl+x`
|
||||
|
||||
4. 重启 ssh 服务，让变更生效。还记得............ 算了直接公布正确答案：
|
||||
|
||||
```shell
|
||||
systemctl restart ssh
|
||||
```
|
||||
|
||||
5. 完整流程演示如下：
|
||||
|
||||
|
||||
|
||||
6. 下次通过 PuTTY 远程 SSH 登录的时候，`root`用户已无法连接，用户名就要换成`vpsadmin`了！方便起见，我们可以在 PuTTY 中把`vpsadmin`设置成默认登录用户名。（啰嗦君：别忘了保存 Session）
|
||||
|
||||
|
||||
|
||||
## 4.7 使用 RSA 密钥登录并禁用密码登录
|
||||
|
||||
第三步，我们来解决【密码】可能被撞破的问题。
|
||||
|
||||
前面我说过，黑客并不是很蠢的用穷举法破解你的密码，而是会用一些比如“密码表”的作弊手段。除非你用的是随机生成的超长密码（比如借助 1Password，或者 macOS 的 keychain 等密码管理工具），否则很容易中招。
|
||||
|
||||
超长随机密码虽然安全性有所提高，但是基本上无法记忆，手动输入也十分麻烦易错。为了解决这个困境，我们可以直接弃用【密码验证】方式，改用更安全的【密钥验证】。
|
||||
|
||||
所谓的【密钥验证】，就是生成【一对】相关联的密钥文件（公钥和私钥），然后把【公钥】上传到 VPS 备用。每次登录时，SSH 会将【公钥】和【私钥】进行匹配，若验证是正确的【密钥对】，则验证通过。（换言之，你无需记忆和输入复杂的密码，只要保护好【私钥】这个文件不外泄即可）
|
||||
- Use `ctrl+w` to enter search mode, then type `Port 22` and press Enter
|
||||
- Delete `22` and replace it with `9753`
|
||||
- Note: If this line starts with `#`, it means that this line is [commented out] and [does not take effect]. You can write a new line at the end of the file without `#`, or delete the `#` to enable this line.
|
||||
|
||||
::: warning
|
||||
本文以 `RSA` 密钥举例，是因为 `RSA` 密钥在各种设备、各种 `SSH` 客户端中有广泛悠久的支持历史，且目前依然能提供够用的安全性。但它绝非唯一选择。
|
||||
|
||||
其他的常见密钥还有：
|
||||
|
||||
- `DSA` - 已经从数学层面被证明不安全，所以永远不要用它
|
||||
- `ECDSA` - 密钥小安全性高，但其算法被指留有 NSA 的后门，如果你的 VPS 上有值得 NSA 关注的东西就不要用它
|
||||
- `Ed25519` - 这是一个与 `ECDSA` 十分类似的算法，故具有相似的性能优势。同时其文档全部公开，所以普遍认为无后门
|
||||
|
||||
所以，如果你的设备和软件都支持的话，我建议优先选择 `Ed25519` 密钥。
|
||||
This article uses `9753` as an example, which means that with the release of this article, this port will become a feature that may be prioritized or blocked by attackers or the Great Firewall of China. Therefore, I strongly recommend that you use another port that you come up with yourself, after all, you have over 60,000 ports to choose from freely.
|
||||
:::
|
||||
|
||||
那我们现在就来配置【密钥验证】吧！
|
||||
6. The third thing we need to do is to [save the file and exit].
|
||||
|
||||
1. 运行`PuTTYgen` (PuTTY 密钥生成器)。位置是 `开始菜单` --> `所有程序` --> `PuTTY (64-bit)` --> `PuTTYgen`
|
||||
- If you observed carefully in step 3, you would have noticed that saving is not done by the common `ctrl+s`.
|
||||
- The correct shortcut keys: save is `ctrl+o` + `enter`, and exit is `ctrl+x`.
|
||||
|
||||
1. 点击`Generate`开始生成（在界面空白处乱晃鼠标增加随机数）
|
||||
7. The last thing we need to do is to [restart the SSH service to make the changes take effect].
|
||||
|
||||
|
||||
```shell
|
||||
systemctl restart ssh
|
||||
```
|
||||
|
||||
::: warning
|
||||
本图中是以 `2048` 位的 `RSA` 密钥为例的。但实际上，如果要获得与 `EDCSA/Ed25519` 的 `256` 位密钥相同的安全性，你需要使用 `3072` 位的 `RSA` 密钥。（即右下角的数字改成 `3072`）
|
||||
:::
|
||||
This is a shell command to restart the SSH service.
|
||||
|
||||
2. 你可以给私钥设置密码，增加一层安全性
|
||||
3. 点击 `Save public key` 保存公钥，文件名为 `id_rsa.pub`
|
||||
4. 点击 `Save private key` 保存私钥，文件名为 `id_rsa` (PuTTY 私钥自带`.ppk`后缀)
|
||||
5. 最重要的，将上方红框内的内容，向下滚动全部复制出来并保存，文件名为 `authorized_keys`。（用 vscode 保存，默认会变成带`txt`后缀的文本文件，这没关系，之后上传 VPS 时我们会把后缀名去掉）
|
||||
8. The complete process demonstration is as follows:
|
||||
|
||||
|
||||
|
||||
|
||||
2. 将公钥上传至 VPS 的`vpsadmin`用户下
|
||||
9. Modify PuTTY Configuration
|
||||
|
||||
1. 这一步就需要用到之前准备的`WinSCP`了。
|
||||
2. 去[官网](https://winscp.net/eng/index.php)下载并安装，会提示你导入 PuTTY 的设置，当然一键导入啦！
|
||||
"Now that the new port is in effect, you will need to use `9753` the next time you log in with PuTTY. So please go to the PuTTY settings to change the port number and save the session. Well, you should know where to change it, right? (If you don't know, you need to reread the previous content!)"
|
||||
|
||||
|
||||
## 4.5 Creating a New User Without Root Access
|
||||
|
||||
3. 如果没有提示导入或者你已经提前安装好了，那按照下图进行配置即可
|
||||
In the second step, let's solve the issue of the username being `root`.
|
||||
|
||||
|
||||
Firstly, you need to understand that `root` in Linux system is not just a simple administrator account. It is the foundation of the entire system, the ruler and the supreme god of the system. Once the `root` account has security issues, the entire system will be vulnerable and there will be nowhere to hide. So, let's follow me to carry out the operations:
|
||||
|
||||
4. WinSCP 左边的目录就是本地电脑上的文件夹和文件，请定位到密钥所在的文件夹
|
||||
1. Little White Linux Basic Commands:
|
||||
|
||||
5. WinSCP 右边的目录则是 VPS 服务器上的文件夹和文件，默认就在 `/home/vpsadmin/` 文件夹，此时在请点击右下角 `X hidden` 来显示隐藏文件
|
||||
| Number | Command Name | Command Description |
|
||||
| :------: | :-----------: | :-----------------------------------------------: |
|
||||
| `cmd-05` | `adduser` | Add new user to the system |
|
||||
| `cmd-06` | `apt install` | Install a software package |
|
||||
| `cmd-07` | `visudo` | Special editor to modify sudo permission settings |
|
||||
|
||||
|
||||
2. The first thing we need to do is to [add a new user and set a login password]. You can choose any name you want, here I will use `vpsadmin` as an example:
|
||||
|
||||
6. 在右边（VPS 中）点击右键并新建文件夹，起名`.ssh` （注意有一个`.`）
|
||||
```shell
|
||||
adduser vpsadmin
|
||||
```
|
||||
|
||||
|
||||
This is a command in the shell terminal to add a new user named "vpsadmin".
|
||||
|
||||
7. 将【公钥】`authorized_keys`上传到`.ssh`文件夹内
|
||||
After executing the command, follow the prompts to operate. Be sure to set a user password (remember that you won't see `******` when setting the password). Afterwards, the system will ask you for some additional user information, which can be ignored by pressing Enter all the way.
|
||||
|
||||
|
||||
|
||||
8. 在上传时，将【公钥】从 `authorized_keys.txt` 改名为 `authorized_keys`（去掉`.txt`这个后缀名）
|
||||
|
||||
|
||||
|
||||
9. 完整流程演示如下：
|
||||
|
||||
|
||||
|
||||
3. 在 VPS 端设置 SSH 启用 RSA 密钥验证登录、同时禁用密码验证登录
|
||||
|
||||
1. 小小白白 Linux 基础命令：
|
||||
| 编号 | 命令名称 | 命令说明 |
|
||||
|:--:|:--:|:--:|
|
||||
| `cmd-08` | `sudo` | 用`root`权限运行某个命令 |
|
||||
| `cmd-09` | `chmod` | 修改目标文件/文件夹的权限 |
|
||||
|
||||
2. SSH 远程连接到 VPS 上（PuTTY）
|
||||
|
||||
3. 修改 `authorized_keys` 文件权限为 `600` （仅所有者可读可写）
|
||||
|
||||
```shell
|
||||
chmod 600 ~/.ssh/authorized_keys
|
||||
```
|
||||
|
||||
4. 修改 SSH 配置。这个我们已经用了很多次，但现在我们已经从无所不能的`root`变成了普通用户`vpsadmin`，此时的我们是没有权限直接编辑 SSH 配置的。这时候就需要使用`sudo`命令了：
|
||||
|
||||
```shell
|
||||
sudo nano /etc/ssh/sshd_config
|
||||
```
|
||||
|
||||
5. 找到(`ctrl+w`) `PasswordAuthentication` 改成 `no`
|
||||
|
||||
6. 找到(`ctrl+w`) `PubkeyAuthentication` 改成 `yes`，然后保存(`ctrl+o`)退出(`ctrl+x`)
|
||||
|
||||
7. 重启 SSH 服务。（啰嗦君：别忘了现在需要使用`sudo`来获得权限）
|
||||
|
||||
```shell
|
||||
sudo systemctl restart ssh
|
||||
```
|
||||
|
||||
8. 完整流程如下:
|
||||
|
||||
|
||||
|
||||
4. VPS 端已经设置好了公钥，现在要给 PuTTY 指定私钥位置供登录时使用（啰嗦君：别忘了保存 Session）
|
||||
|
||||
|
||||
|
||||
5. 至此，【密钥登录】已成功开启、【密码验证】已成功关闭、并且还给 PuTTY 保存了默认的登录用户名和私钥。未来使用 PuTTY 登录时，载入`VPS-SERVER`配置后，点击`Open`就可以一键登录了。
|
||||
|
||||
如果你给私钥设置了密码保护，登录时当然还需要输入这个密码才能使用密钥，如下图：
|
||||
|
||||
|
||||
|
||||
6. 别忘了给`WinSCP`也做对应的密钥设置，否则之后想要传输文件时就无法登录了：
|
||||
|
||||
|
||||
|
||||
|
||||
::: warning
|
||||
任何需要借助 SSH 进行登录的软件都需要密钥验证了，软件过多，无法逐一展示，请根据你的需要自行设置好哦
|
||||
This article takes "vpsadmin" as an example, which means that with the release of this article, this username will also become a significant feature, and may be the first choice for attackers to try. Therefore, just like ports, I strongly recommend that you use another username that you come up with yourself.
|
||||
:::
|
||||
|
||||
3. The complete process demonstration is as follows:
|
||||
|
||||
|
||||
|
||||
4. The second thing we need to do is to install the `sudo` function (which allows ordinary accounts to temporarily obtain the power of `root` at critical moments and unleash their full power to save the world).
|
||||
|
||||
```shell
|
||||
apt update && apt install sudo
|
||||
```
|
||||
|
||||
This is a shell command to update the package list and install the "sudo" package.
|
||||
|
||||
You may have noticed that this command actually consists of two commands. The first half, `apt update`, you have seen and used before, is to refresh the software version information on the server. The latter half, `apt install`, is the installation command that will be used this time. The two commands are connected together to instruct the system to refresh the latest available software and then install the latest version of the `sudo` program. `&&` is used to link the two commands together for execution.
|
||||
|
||||
5. The third thing we need to do is to add the `vpsadmin` user to the `sudo` list, so that they have the privilege to borrow the power of `root`.
|
||||
|
||||
```shell
|
||||
visudo
|
||||
```
|
||||
|
||||
(Note: `visudo` is a command used in Linux/Unix systems to edit the sudoers file, which specifies which users or groups are allowed to run certain commands with administrative privileges.)
|
||||
|
||||
Simply add the following line under `User Privilege Specification`: `vpsadmin ALL=(ALL) NOPASSWD: ALL`.
|
||||
|
||||
::: warning
|
||||
I want to specifically explain the setting of `NOPASSWD`. It means that when the `vpsadmin` user temporarily uses the `root` permission, no additional password needs to be entered. This is contrary to general security recommendations. The reason why I recommend this is that many newcomers insist on using the `root` account because they feel relaxed when using `root` without repeatedly entering passwords. "Choosing the lesser of two evils," I believe that the risk of [directly using the `root` user] is greater than the risk of [not entering a password when using `sudo`], so I made the above suggestion.
|
||||
|
||||
If you want to follow the traditional practice and enter a password every time you use `sudo`, then you can change this line to `vpsadmin ALL=(ALL:ALL) ALL`.
|
||||
|
||||
6. The complete process demonstration is as follows:

## 4.6 Disabling SSH Remote Login for Root User
|
||||
|
||||
1. Now that you're gradually getting familiar with Linux, it's time for you to think. What's the first thing we need to do? That's right, it's still to use the `nano` editor to open the `SSH remote login program settings`. What? You can't remember how to do it? Then go back and review the content above and come back! ............ Correct answer:
|
||||
|
||||
```shell
|
||||
nano /etc/ssh/sshd_config
|
||||
```
|
||||
|
||||
This is a command line instruction to open and edit the `sshd_config` file located at `/etc/ssh/` using the `nano` text editor.
|
||||
|
||||
2. Find the line `PermitRootLogin Yes`, and change the value after it to `no`. Do you remember how to do it? ............ Correct answer:
|
||||
|
||||
- Use `ctrl+w` to enter search mode, then enter `PermitRootLogin` and press enter.
|
||||
- Delete `yes` and change it to `no`.
|
||||
|
||||
3. Save the file and exit. Do you remember how to do it? ............ Correct answer: N/A (The correct answer is not provided in the given text.)
|
||||
|
||||
- Save is `ctrl+o`, then press `Enter` to confirm.
|
||||
- Exit is `ctrl+x`.
|
||||
|
||||
4. Restart the ssh service to make the changes take effect. Do you remember...? Never mind, let's just reveal the correct answer:
|
||||
|
||||
```shell
|
||||
systemctl restart ssh
|
||||
```
|
||||
|
||||
(This is a Linux shell command to restart the SSH service.)
|
||||
|
||||
5. The complete process is demonstrated as follows:
|
||||
|
||||
|
||||
|
||||
6. Next time you log in remotely via SSH using PuTTY, you will no longer be able to connect as the `root` user. You will need to use the username `vpsadmin` instead. For convenience, you can set `vpsadmin` as the default login username in PuTTY. (Tip: Don't forget to save the session.)
|
||||
|
||||
|
||||
|
||||
## 4.7 Login with RSA Key and Disable Password Login
|
||||
|
||||
In the third step, we will solve the problem of the password being cracked.
|
||||
|
||||
As mentioned earlier, hackers are not foolish enough to crack your password by brute force, but rather they use cheating methods such as "password tables". Unless you use a randomly generated super long password (such as with 1Password, or macOS keychain and other password management tools), it's easy to fall victim to this.
|
||||
|
||||
Although a very long random password can improve security, it is usually difficult to remember and manually enter, which can also lead to mistakes. To solve this problem, we can simply abandon the "password verification" method and switch to a more secure "key verification" method.
|
||||
|
||||
The so-called "key authentication" refers to generating a pair of related key files (public key and private key), uploading the "public key" to the VPS for backup. Each time you log in, SSH will match the "public key" and "private key". If the verification is correct, the "key pair" will be verified and the authentication will pass. (In other words, you don't need to remember and enter complex passwords, just protect the "private key" file from being leaked.)
|
||||
|
||||
::: warning
|
||||
This article uses `RSA` keys as an example because `RSA` keys have a long history of support in various devices and `SSH` clients and can still provide sufficient security. However, it is not the only choice available.
|
||||
|
||||
Other common keys include:
|
||||
|
||||
- `DSA` - It has been mathematically proven to be insecure, so never use it.
|
||||
- `ECDSA` - It has high security with small keys, but its algorithm is suspected to have a backdoor by the NSA. If there is something on your VPS that is worth the attention of the NSA, do not use it.
|
||||
- `Ed25519` - This is an algorithm that is very similar to `ECDSA`, and it has similar performance advantages. At the same time, all of its documentation is public, so it is generally considered to be free of backdoors.
|
||||
|
||||
So, if your device and software both support it, I recommend choosing `Ed25519` keys as a priority.
|
||||
:::
|
||||
|
||||
## 4.8 你的进度
|
||||
Now let's configure the [Key Authentication]!
|
||||
|
||||
到这里为止，你的 VPS 已经完成了【端口】、【用户名】、【密码】这三要素的基本安全保障，虽然远称不上固若金汤，但一般的恶意脚本应该已经无法对你造成伤害了！
|
||||
1. Run `PuTTYgen` (PuTTY Key Generator). The location is `Start Menu` --> `All Programs` --> `PuTTY (64-bit)` --> `PuTTYgen`.
|
||||
|
||||
现在我们终于有了一个安全的系统基础，下一章，我们就可以开始逐步安装配置 Xray 需要的基础设施了！（什么基础设施呢？一个网页，一张证书）
|
||||
1. Click on `Generate` to start the generation process (move the mouse randomly in the blank area of the interface to add random numbers).
|
||||
|
||||
> ⬛⬛⬛⬛⬜⬜⬜⬜ 50%
|
||||
|
||||
|
||||
::: warning
|
||||
The example in this image is based on a `2048`-bit `RSA` key. However, in reality, if you want to achieve the same level of security as a `256`-bit key for `EDCSA/Ed25519`, you need to use a `3072`-bit `RSA` key. (i.e., change the number in the bottom right corner to `3072`)
|
||||
:::
|
||||
|
||||
2. You can add a password to your private key to increase security.
|
||||
3. Click on `Save public key` to save the public key with the file name `id_rsa.pub`.
|
||||
4. Click on `Save private key` to save the private key with the file name `id_rsa` (PuTTY private keys come with the `.ppk` extension).
|
||||
5. Most importantly, copy and save all the content inside the red box below by scrolling down, with the file name `authorized_keys`. (If you save it using vscode, it will be saved as a text file with a `.txt` extension, which is fine. We will remove the extension when uploading it to VPS later.)
|
||||
|
||||
|
||||
|
||||
2. Upload the public key to the "vpsadmin" user on the VPS.
|
||||
|
||||
1. This step requires the use of the previously prepared `WinSCP`.
|
||||
2. Go to the [official website](https://winscp.net/eng/index.php) to download and install. It will prompt you to import PuTTY settings, and of course, you can import them with one click!
|
||||
|
||||
|
||||
|
||||
3. If there is no prompt for import or you have already installed it in advance, configure it according to the following figure.
|
||||
|
||||
|
||||
|
||||
4. The directory on the left side of WinSCP is the folder and files on your local computer. Please locate the folder where the key is stored.
|
||||
|
||||
5. The directory on the right side of WinSCP is the folder and files on the VPS server, which are located in the `/home/vpsadmin/` folder by default. To display hidden files, please click on `X hidden` in the lower right corner.
|
||||
|
||||
|
||||
|
||||
6. Right-click on the right side (in VPS) and create a new folder named `.ssh` (note the period at the beginning).
|
||||
|
||||
|
||||
|
||||
7. Upload the [public key] `authorized_keys` to the `.ssh` folder.
|
||||
|
||||
|
||||
|
||||
8. When uploading, rename the [public key] from `authorized_keys.txt` to `authorized_keys` (remove the `.txt` extension).
|
||||
|
||||
|
||||
|
||||
9. The complete process demonstration is as follows:
|
||||
|
||||
|
||||
|
||||
3. Enable RSA key authentication for SSH login and disable password authentication login on the VPS side.
|
||||
|
||||
1. Basic Linux Commands:
|
||||
| Number | Command | Description |
|
||||
| :------: | :-----: | :-----------------------------------------------: |
|
||||
| `cmd-08` | `sudo` | Run a command with `root` privileges |
|
||||
| `cmd-09` | `chmod` | Change the permissions of a target file/directory |
|
||||
|
||||
2. SSH remote connection to VPS (PuTTY)
|
||||
|
||||
3. Change the permission of the `authorized_keys` file to `600` (only the owner can read and write).
|
||||
|
||||
```shell
|
||||
chmod 600 ~/.ssh/authorized_keys
|
||||
```
|
||||
|
||||
This is a command in shell script to change the permissions of the `authorized_keys` file to `600` for the current user's SSH directory (`~/.ssh/`).
|
||||
|
||||
4. Modify SSH configuration. We have used this many times, but now that we have changed from the almighty `root` to the ordinary user `vpsadmin`, we do not have the permission to edit SSH configuration directly. At this time, we need to use the `sudo` command:
|
||||
|
||||
```shell
|
||||
sudo nano /etc/ssh/sshd_config
|
||||
```
|
||||
|
||||
(This is a command in the shell/terminal to open the sshd_config file located in the /etc/ssh/ directory with the sudo privilege using the nano text editor.)
|
||||
|
||||
5. Find (`ctrl+w`) `PasswordAuthentication` and change it to `no`.
|
||||
|
||||
6. Find (`ctrl+w`) `PubkeyAuthentication`, change it to `yes`, then save (`ctrl+o`) and exit (`ctrl+x`).
|
||||
|
||||
7. Restart the SSH service. (Note: Don't forget to use `sudo` to gain permission.)
|
||||
|
||||
```shell
|
||||
sudo systemctl restart ssh
|
||||
```
|
||||
|
||||
This is a command in the shell terminal to restart the SSH service with root privileges using the `systemctl` command.
|
||||
|
||||
8. The complete process is as follows:
|
||||
|
||||
|
||||
|
||||
4. The public key has been set up on the VPS end. Now we need to specify the private key location for PuTTY to use when logging in. (Reminder: Don't forget to save the session.)
|
||||
|
||||
|
||||
|
||||
5. Now, the [Key-based login] has been successfully enabled, [Password authentication] has been successfully disabled, and the default login username and private key have been saved for PuTTY. In the future, when using PuTTY to log in, simply load the `VPS-SERVER` configuration, click `Open`, and you can log in with just one click.
|
||||
|
||||
If you have set a password for your private key, you need to enter this password to use the key when logging in, as shown in the following figure:
|
||||
|
||||
|
||||
|
||||
6. Don't forget to set the corresponding key for `WinSCP`, otherwise you won't be able to log in when you want to transfer files later.
|
||||
|
||||
|
||||
|
||||
::: warning
|
||||
Any software that requires SSH login needs key verification. As there are too many software, it is impossible to show them one by one. Please set it up according to your needs.
|
||||
:::
|
||||
|
||||
## 4.8 Your Progress
|
||||
|
||||
Up to this point, your VPS has completed the basic security measures of [port], [username], and [password]. Although it is not completely impregnable, most malicious scripts should no longer be able to harm you.
|
||||
|
||||
Now that we finally have a secure system foundation, in the next chapter, we can start step by step to install and configure the infrastructure that Xray needs! (What infrastructure? A web page, a certificate)

# 【第 5 章】网站建设篇
|
||||
# Chapter 5: Website Building
|
||||
|
||||
## 5.1 为什么要做一个网站？
|
||||
## 5.1 Why should you create a website?
|
||||
|
||||
新人也许会迷惑，为什么科学上网还要建一个网站？我不会编程啊，是不是特别麻烦？
|
||||
Some newcomers may be confused: why do I need to build a website for securing an open digital environment? I don't know how to code! Isn't it very complicated?
|
||||
|
||||
先回答第一个问题，建网站的原因有：
|
||||
First, let's answer the first question. The reasons for building a website are:
|
||||
|
||||
1. 申请合法的 TLS 证书（非常重要）
|
||||
2. 提供合理的回落，防止主动探测攻击，提高安全性
|
||||
3. 建设一个伪装站（如博客、私人网盘、多媒体网站、游戏网站等），直接访问时有合理的前台，使流量使用看上去更合理。
|
||||
1. Apply for a legitimate TLS certificate (very important)
|
||||
2. Provide reasonable fallback to prevent active probing attacks and improve security
|
||||
3. Set up a camouflage site (such as a blog, private cloud storage, multimedia site, game site, etc.) with a reasonable frontend when directly accessed, making traffic usage look more legitimate.
|
||||
|
||||
再回答第二个问题：
|
||||
Now let's answer the second question:
|
||||
|
||||
1. 本文作为演示，仅仅使用了一个最简单的【单文件 html 页面 + Nginx】来搭建，以此完成上面的目标，所以【非常简单】
|
||||
2. 这个网站完全可以不仅仅是伪装，而是真的做大做强，这个复杂性就完全取决于你了
|
||||
3. 对于“伪装”和“网站运营”这个目标，需要的就是各不相同、秀出真我，需要的同学可以自行搜索学习。这个内容已经完全偏离了科学上网，本文就不深入解析了。
|
||||
1. As a demonstration, this article uses only the simplest "single-file HTML page + Nginx" setup to achieve the above objectives, so it is **very easy**.
|
||||
2. This website can not only be used for camouflage but also for real development and growth. The complexity depends entirely on you.
|
||||
3. For the goals of "camouflage" and "website operation", uniqueness and personalization are needed. Students who need this can search and learn by themselves. This content has completely deviated from scientific online access, so this article will not go into depth.
|
||||
|
||||
## 5.2 登录 VPS、安装运行 Nginx
|
||||
## 5.2 Log in to VPS, install and run Nginx
|
||||
|
||||
1. 这里用到的，都是之前已经详解过的命令，所以就不重复讲解了。看不懂的同学可以看看前面的章节哦。
|
||||
1. Here we use commands that have been explained in detail before, so they won't be repeated. If you don't understand, please refer to the previous chapters.
|
||||
|
||||
```shell
|
||||
sudo apt update && sudo apt install nginx
|
||||
```
|
||||
|
||||
2. 完成后，Nginx 已经自动运行。此时打开 Windows 上的浏览器并输入 `http://100.200.300.400:80`，若看到下图的界面就说明 Nginx 已经正常在运行了。
|
||||
2. After completion, Nginx will automatically run. Open the browser on Windows and enter `http://100.200.300.400:80`. If you see the interface shown below, it means Nginx is running normally.

## 5.4 常见错误的说明
|
||||
## 5.4 Common error explanations
|
||||
|
||||
首先，如果你一路按照文章的说明来操作，并且足够细心，那肯定不会出错。所以，我并不打算修改本文的写法。
|
||||
First of all, if you follow the instructions in the article step by step and are careful enough, you will definitely not encounter any errors. So, I don't intend to change how this article is written.
|
||||
|
||||
那为什么依然有很多同学卡在了这一步，网页怎么也打不开呢？基本上就是两个字：**粗心**。因为这里配置可能出现的问题只有两种，原因也只有两个。
|
||||
Then why do some students still get stuck at this step, and the web page just won't open? There are basically two words: **carelessness**. Because there are only two possible issues with the configuration here, and there are only two reasons for them.
|
||||
|
||||
一、两种问题：
|
||||
I. Two types of issues:
|
||||
|
||||
- `nginx.conf` 里面的 `/home/vpsadmin/www/webpage` 这一条，与你的实际文件路径不符，`nginx` 找不到文件
|
||||
- 路径正确，但 `nginx` 无权读取
|
||||
- In `nginx.conf`, the `/home/vpsadmin/www/webpage` does not match the actual file path; `nginx` cannot find the file
|
||||
- The path is correct, but `nginx` doesn't have permission to access it
|
||||
|
||||
二、两个原因：
|
||||
II. Two reasons:
|
||||
|
||||
- 使用了【非 `root` 用户】，但仍然直接拷贝文中的命令不加修改。（这基本就等于抄答案时把同学的名字一起抄过去了）
|
||||
- 坚持使用【 `root` 用户】
|
||||
- Use a **non-root user** but still directly copy the commands in the text without modification. (This is basically like copying the name of another student when copying answers)
|
||||
- Insist on using a **root user**
|
||||
|
||||
碰到错误的同学，就回过头仔细看一下【5.3】中【第 3 步】和【第 5-2 步】的说明吧。
|
||||
If you encounter any errors, please carefully review the explanations in Steps 3 and 5-2 of Section 5.3.
|
||||
|
||||
::: warning
|
||||
本文前期已经用了大量篇幅说明了使用【非 `root` 用户】对安全的重要性，全文也是基于此而写。所以，因使用【 `root` 用户】而导致的问题并不在本文的设计范围里。
|
||||
In the early stages of this article, a lot of space has been devoted to explaining the importance of using a **non-root user** for security, and the entire article is written based on this premise. So, issues caused by using a **root user** are not within the scope of this article.
|
||||
|
||||
但我相信，坚持使用【 `root` 用户】的同学应该是有主见、动手能力强、或者有一定 Linux 基础的同学。问题的症结我已经全部说明了，我相信你一定可以自行解决。
|
||||
:::
|
||||
|
||||
## 5.5 你的进度
|
||||
But I believe that students who persist in using the `root` user should have their own opinions, strong hands-on ability, or have a certain foundation in Linux. I have already explained the crux of the problem, and I believe you can solve it on your own.

## 6.1 Applying for a TLS Certificate
|
||||
|
||||
接下来我们要做的，是为我们的域名申请一个真实的 TLS 证书，使网站具备标准 TLS 加密的能力及 HTTPS 访问的能力。这就是 Xray 等现阶段安全代理工具确保流量充分加密最重要的工具。
|
||||
Next, we need to apply for a real TLS certificate for our domain name, so that the website has the ability to encrypt with standard TLS and the ability to access via HTTPS. This is the most important tool for Xray and other current security proxy tools to ensure fully encrypted traffic.

||||

请不要轻易使用自签证书。它并没有让操作简单太多，但增加了无谓的风险（如中间人攻击）。

Here, I will use a certificate management tool called [`acme.sh`](https://github.com/acmesh-official/acme.sh), which is simple, lightweight, efficient, and capable of automatically updating certificates.
|
||||
|
||||
另外，我相信，现在你已经逐渐熟悉了 Linux 的基础操作，所以已经多次出现的命令从本章开始不再重复截图、只做简单的描述。如果实在想不起来怎么用的话，就稍微复习一下前面的章节吧。
|
||||
In addition, I believe that you have gradually become familiar with the basic operations of Linux. Therefore, from this chapter on, commands that have appeared multiple times will no longer have screenshots and will only be briefly described. If you really can't remember how to use them, just review the previous chapters.

1. 小小白白 Linux 基础命令：
|
||||
| 编号 | 命令名称 | 命令说明 |
|
||||
|:--:|:--:|:--:|
|
||||
| `cmd-12` | `wget` | 访问（或下载）某个网页文件 |
|
||||
| `cmd-13` | `acme.sh` | acme.sh 证书管理相关的命令 |
|
||||
1. Basic Linux commands for beginners:
|
||||
| Number | Command | Description |
|
||||
| :------: | :-------: | :------------------------------------------------: |
|
||||
| `cmd-12` | `wget` | Retrieve (or download) a webpage file |
|
||||
| `cmd-13` | `acme.sh` | Commands related to acme.sh certificate management |
|
||||
|
||||
2. 运行安装脚本
|
||||
2. Run the installation script.
|
||||
|
||||
```shell
|
||||
wget -O - https://get.acme.sh | sh
|
||||
```
|
||||
```shell
|
||||
wget -O - https://get.acme.sh | sh
|
||||
```
|
||||
|
||||
3. 让 `acme.sh` 命令生效
|
||||
3. Make the `acme.sh` command effective.
|
||||
|
||||
```shell
|
||||
. .bashrc
|
||||
```
|
||||
```shell
|
||||
. .bashrc
|
||||
```
|
||||
|
||||
4. 开启 `acme.sh` 的自动升级
|
||||
(Note: This command is used to source (load) the `.bashrc` file in the shell environment.)
|
||||
|
||||
```shell
|
||||
acme.sh --upgrade --auto-upgrade
|
||||
```
|
||||
4. Enable `acme.sh` automatic upgrade.
|
||||
|
||||
5. 到这一步的完整流程如下图：
|
||||
```shell
|
||||
acme.sh --upgrade --auto-upgrade
|
||||
```
|
||||
|
||||
|
||||
5. The complete process up to this point is shown in the following diagram:
|
||||
|
||||
## 6.3 测试证书申请
|
||||
|
||||
|
||||
在正式申请证书之前，我们先用测试命令(`--issue --test`)来验证是否可以成功申请，这样可以避免在本地配置有误时，反复申请证书失败，超过 Let's Encrypt 的频率上限（比如，每小时、每个域名、每个用户失败最多 5 次），导致后面的步骤无法进行。
|
||||
## 6.3 Testing Certificate Application
|
||||
|
||||
1. 测试证书申请的命令如下（本文均以 `ECC` 证书为例，因为时至今日，实在没什么理由不用它）：
|
||||
Before officially applying for the certificate, we use the testing command (`--issue --test`) to verify if the application can be successfully submitted. This can avoid repeated failures in applying for a certificate due to incorrect local configuration, exceeding the frequency limit of Let's Encrypt (such as a maximum of 5 failures per hour, per domain, or per user), which may prevent the subsequent steps from being carried out.
|
||||
|
||||
```shell
|
||||
acme.sh --issue --server letsencrypt --test -d 二级域名.你的域名.com -w /home/vpsadmin/www/webpage --keylength ec-256
|
||||
```
|
||||
1. The command to apply for a test certificate is as follows (this article uses ECC certificate as an example, because there is really no reason not to use it nowadays):
|
||||
|
||||
::: warning 说明
|
||||
`ECC`证书的主要优势在于它的 Keysize 更小，意味着同等大小下安全性的提升和加密解密速度的加快。如 ECC-256bit 的强度大约相当于 RSA-3072bit，何乐而不为呢？当然，有人说 ECC 证书握手会明显更快，这我觉得就有些夸张了，因为 RSA 握手也没有太慢，就算有差别应该也是毫秒级，很难直接感知。
|
||||
```shell
|
||||
acme.sh --issue --server letsencrypt --test -d subdomain.yourdomain.com -w /home/vpsadmin/www/webpage --keylength ec-256
|
||||
```
|
||||
|
||||
另外，如果有些网站确实需要兼容某些古老设备的，那也还是请按需选择`RSA`证书。
|
||||
(Note: This is a command in shell script for obtaining SSL certificate from Let's Encrypt CA using ACME protocol. It specifies the test server, the subdomain for which the certificate is requested, the webroot directory of the subdomain, and the key length to use for the certificate.)
|
||||
|
||||
::: warning Explanation
|
||||
The main advantage of the `ECC` certificate is that its `Keysize` is smaller, which means that security is improved and encryption and decryption speed is faster for the same size. Why not choose ECC-256bit, which is approximately equivalent to RSA-3072bit in strength? Of course, some people say that the ECC certificate handshake is significantly faster, which I think is a bit exaggerated, because RSA handshake is not too slow either. Even if there is a difference, it should be in milliseconds and difficult to perceive directly.
|
||||
|
||||
In addition, if some websites do need to be compatible with certain old devices, please still choose RSA certificates according to your needs.
|
||||

3. Note: The certificate applied for here is a test certificate, which cannot be used directly. It is only used to prove that your domain and configuration are correct. If you observe carefully, you will find that the domain that issues the certificate to you is `https://acme-staging-v02.api.letsencrypt.org`, and this `staging` can be understood as a "test server"!
|
||||
|
||||
4. If this step goes wrong, you can run the following command to check the detailed application process and specific errors. If you don't understand, you can hide sensitive information and ask in the Xray group.
|
||||
|
||||
```shell
|
||||
acme.sh --issue --server letsencrypt --test -d subdomain.yourdomain.com -w /home/vpsadmin/www/webpage --keylength ec-256 --debug
|
||||
```
|
||||
|
||||
(Note: This command is written in Chinese characters, therefore I have translated it into English. The command is used to issue SSL/TLS certificates using acme.sh client with Let's Encrypt CA in test mode for a subdomain of your domain with the specified webroot path, key length and in debug mode.)
|
||||
|
||||
Hmm, that's right. Just added a `--debug` parameter at the end of the command.
|
||||
|
||||
5. Once this step is confirmed to be successful, you can apply for the formal certificate. (The test certificate does not need to be deleted, as it will be automatically replaced by the formal certificate.)
|
||||
|
||||
## 6.4 Application for Official Certification
|
||||
|
||||
1. The command for applying for an official certificate is as follows (i.e., remove the `--test` parameter and add the `--force` parameter at the end):
|
||||
|
||||
```shell
|
||||
acme.sh --set-default-ca --server letsencrypt
|
||||
```
|
||||
|
||||
This is a command in the shell language. It sets the default Certificate Authority (CA) to Let's Encrypt by using the `acme.sh` script.
|
||||
|
||||
```shell
|
||||
acme.sh --issue -d subdomain.yourdomain.com -w /home/vpsadmin/www/webpage --keylength ec-256 --force
|
||||
```
|
||||
|
||||
(Note: This is a command written in shell script that requests a SSL certificate from ACME server using the ACME client "acme.sh". It specifies the subdomain of the domain name, the web root directory of the website, the key length, and forces the re-issuance of the certificate.)
|
||||
|
||||
::: warning Explanation
|
||||
The meaning of the `--force` parameter is to manually (forcefully) update the certificate before the existing certificate expires. Although the certificate we applied for from the "test server" in the previous step cannot be used directly, it has not expired yet, so this parameter is needed.

|
||||
```
|
||||
|
||||
3. 注意：这里申请的是测试证书，没办法直接用的，只是用来证明你的域名、配置全都正确。仔细观察，你会发现给你发证书的域名是 `https://acme-staging-v02.api.letsencrypt.org`，这个 `staging` 你就理解成【测试服】吧！
|
||||
3. If you observe carefully, you will find that the domain name that issues the certificate to you this time is `https://acme-v02.api.letsencrypt.org`, which lacks the word `staging`. Therefore, this is the [Production Environment]!
|
||||
|
||||
4. 如果这一步出错的话，你可以运行下面的命令，来查看详细的申请过程和具体的错误。（看不懂就隐藏掉敏感信息后，去 Xray 群里问吧）
|
||||
## 6.5 Certificate Installation
|
||||
|
||||
```shell
|
||||
acme.sh --issue --server letsencrypt --test -d 二级域名.你的域名.com -w /home/vpsadmin/www/webpage --keylength ec-256 --debug
|
||||
```
|
||||
1. After completing the certificate application, it needs to be installed to a specified location and referenced in the configuration file to take effect:
|
||||
|
||||
嗯没错，就是在命令的最后加了一个 `--debug` 参数
|
||||
```shell
|
||||
vpsadmin@vps-server:~$ acme.sh --installcert -d subdomain.yourdomain.com --cert-file /path/to/install/cert.crt --key-file /path/to/install/cert.key --fullchain-file /path/to/install/fullchain.crt --ecc

5. 这一步确定成功之后，就可以申请正式的证书了。（测试证书不需要删除，它会自动被正式证书覆盖）
|
||||
(Note: This is a shell command for installing a SSL certificate using acme.sh. The command is specifying the domain, file paths for the certificate, private key, and full chain, as well as indicating that an ECC certificate should be used.)
|
||||
|
||||
## 6.4 正式证书申请
|
||||
## 6.6 Your Progress
|
||||
|
||||
1. 申请正式证书的命令如下（即删掉 `--test` 参数，并在最后加入 `--force`参数）：
|
||||
At this point, the two basic infrastructures required by Xray are finally in place! Xray, which has been eagerly awaited, is about to be revealed, and we are finally about to enter the most exciting chapter!
|
||||
|
||||
```shell
|
||||
acme.sh --set-default-ca --server letsencrypt
|
||||
```
|
||||
|
||||
```shell
|
||||
acme.sh --issue -d 二级域名.你的域名.com -w /home/vpsadmin/www/webpage --keylength ec-256 --force
|
||||
```
|
||||
|
||||
::: warning 说明
|
||||
`--force` 参数的意思就是，在现有证书到期前，手动（强行）更新证书。上一步我们从“测试服”申请的证书虽然不能直接用，但是它本身是尚未过期的，所以需要用到这个参数。

||||

VLESS 是一种很轻的协议，和 Trojan 一样，不对流量进行复杂的加密和混淆，而是大隐隐于市，通过 TLS 协议加密，混杂在其他 HTTPS 流量中，在墙内外穿进穿出。为了更好的伪装以应对主动探测，Fallbacks 回落功能随 VLESS 同时出现。这篇教程将演示如何使用 Xray 中 VLESS 入站协议的回落功能配合 Nginx 或 Caddy 在保证伪装完全的前提下实现按域名分流。
|
||||
VLESS is a lightweight protocol that, like Trojan, does not perform complex encryption and obfuscation on traffic. Instead, it is encrypted through the TLS protocol and mixed in with other HTTPS traffic, making it difficult to detect. In order to better disguise itself and respond to active probing, the fallback function appeared with VLESS at the same time. This tutorial will demonstrate how to use the fallback function of VLESS inbound protocol in Xray, combined with Nginx or Caddy, to achieve domain name-based traffic routing while ensuring complete disguise.

## 应用情景
|
||||
## Application Scenarios
|
||||
|
||||
由于 XTLS，Xray 需要监听 443 端口，这导致如果之前有网站运行在服务器上，那么此时网站无法运行或需要运行在其他端口上，这显然是不合理的。有以下三种方案可以解决这个问题：
|
||||
Due to XTLS, Xray needs to listen on port 443, which means that if there is a website running on the server, it cannot run or needs to run on another port, which is obviously unreasonable. There are three solutions to this problem:
|
||||
|
||||
- Xray 监听其他常用端口（如 22、3389、8443）
|
||||
- Xray monitors other commonly used ports (such as 22, 3389, 8443).
|
||||
|
||||
这个方案是最简单的，但不够完美。
|
||||
This plan is the simplest, but not perfect enough.
|
||||
|
||||
- Nginx 或 HAProxy 监听 443 端口，通过 SNI 分流做 L4 反向代理，实现端口复用
|
||||
- Nginx or HAProxy listens on port 443, uses SNI for L4 load balancing, and achieves port multiplexing through reverse proxy.
|
||||
|
||||
这个方案比较复杂，需要对 Nginx 或 HAProxy 的使用有一定了解，此处不作过多解释。
|
||||
This plan is relatively complicated and requires some understanding of using Nginx or HAProxy. We will not explain it in too much detail here.
|
||||
|
||||
- Xray 监听 443 端口，通过 Fallbacks 功能 SNI 分流将网站流量回落到 Nginx 或 Caddy
|
||||
- Xray listens on port 443, and uses Fallbacks feature to split website traffic based on SNI and fallbacks it to Nginx or Caddy.
|
||||
|
||||
这个方案难度适中，也是此教程接下来想要演示的方案。
|
||||
This plan has a moderate level of difficulty and is the scheme that this tutorial will demonstrate next.
|
||||
|
||||
## SNI 简介
|
||||
## Introduction to SNI
|
||||
|
||||
服务器名称指示（英语：**S**erver **N**ame **I**ndication，缩写：**SNI**）是 TLS 的一个扩展协议。熟悉反向代理的朋友都知道，如果想要通过域名将流量代理到正确的内容上，需要以下配置：
|
||||
Server Name Indication (SNI) is an extension protocol of TLS. Friends who are familiar with reverse proxies know that the following configuration is required if you want to proxy traffic to the correct content through a domain name:
|
||||
|
||||
```nginx
|
||||
proxy_set_header Host 主机名;
|
||||
proxy_set_header Host hostname;
|
||||
```
|
||||
|
||||
这句的作用是将名为 “Host” 的 HTTP Header 设定为某个主机名。为什么要这样做？一般而言，一台服务器对应一个 IP，但却运行多个网站，访问者通过域名查询到 IP 以访问服务器，那么问题来了，如何确定访问者想要访问的是哪一个网站？这需要“基于名称的虚拟主机”。
|
||||
(Note: "hostname" should be replaced with the actual hostname.)
|
||||
|
||||
当 Web 服务器收到访问请求后，它会查看请求的主机头，使访问者访问正确的网站。然而当 HTTP 协议被 TLS 协议加密后，这种简单的方法就无法实现了。因为 TLS 握手发生在服务器看到任何 HTTP 头之前，因此，服务器不可能使用 HTTP 主机头中的信息来决定呈现哪个证书，更无法决定访问者的访问目标。
|
||||
This sentence sets the HTTP Header named "Host" to a certain hostname. Why do we need to do this? Generally, one server corresponds to one IP address, but it runs multiple websites. Visitors access the server by querying the IP address via domain name to visit the website. Then the question arises, how to determine which website the visitor wants to access? This requires "name-based virtual hosting".
|
||||
|
||||
SNI 的原理也很简单，它通过让客户端发送主机名作为 TLS 协商的一部分来解决此问题。所以在使用 Nginx 对 HTTPS 协议进行反向代理时，需要在配置中加入 `proxy_ssl_server_name on;`，此时 Nginx 会向被代理的服务器发送 SNI 信息，解决了 HTTPS 协议下虚拟主机失效的问题。另外，使用 SNI 时，即使不指定主机头，也可以正确访问网站。
|
||||
When a Web server receives a request, it looks at the host header to direct the visitor to the correct website. However, this simple method cannot be used when HTTP protocol is encrypted by TLS protocol. This is because the TLS handshake occurs before the server sees any HTTP headers, so the server cannot use the information in the HTTP host header to determine which certificate to present or which destination the visitor wants to access.
|
||||
|
||||
## 思路
|
||||
The principle of SNI is also very simple. It solves the problem by allowing the client to send the hostname as part of the TLS negotiation. Therefore, when using Nginx to reverse proxy the HTTPS protocol, you need to add `proxy_ssl_server_name on;` to the configuration. At this time, Nginx will send SNI information to the proxied server, solving the problem of virtual host failure under the HTTPS protocol. In addition, when using SNI, even if the host header is not specified, the website can be accessed correctly.
|
||||
|
||||
|
||||
## Idea
|
||||
|
||||
从 443 端口接收到流量后，Xray 会把 TLS 解密后首包长度 < 18、协议版本无效或身份认证失败的流量通过对 name、path、alpn 的匹配转发到 dest 指定的地址。
|
||||
|
||||
|
||||
## 添加 DNS 记录
|
||||
After receiving traffic from port 443, Xray will decrypt the TLS and forward the traffic that has a first packet length < 18, invalid protocol version, or failed authentication through matching name, path, and alpn to the address specified by dest.
|
||||
|
||||
|
||||
## Adding DNS Records
|
||||
|
||||
请按实际情况修改域名和 IP。
|
||||
|
||||
|
||||
## 申请 TLS 证书
|
||||
Please modify the domain name and IP according to the actual situation.
|
||||

||||
由于要对不同前缀的域名进行分流，但一个通配符证书的作用域仅限于两“.”之间（例如：申请 `*.example.com`，`example.com` 和 `*.*.example.com` 并不能使用该证书），故需申请 [SAN](https://zh.wikipedia.org/wiki/%E4%B8%BB%E9%A2%98%E5%A4%87%E7%94%A8%E5%90%8D%E7%A7%B0) 通配符证书。根据 Let's Encrypt 官网信息[^1]，申请通配符证书要求 DNS-01 验证方式，此处演示 NS 记录为 Cloudflare 的域名通过 [acme.sh](https://acme.sh) 申请 Let's Encrypt 的免费 TLS 证书。使用其他域名托管商的申请方法请阅读 [dnsapi · acmesh-official/acme.sh Wiki](https://github.com/acmesh-official/acme.sh/wiki/dnsapi)。
|
||||
## Applying for TLS Certificate
|
||||
|
||||
首先需要到 [Cloudflare 面板](https://dash.cloudflare.com/profile/api-tokens)创建 API Token。参数如下：
|
||||
As it is necessary to route traffic to different domain name prefixes, but a wildcard certificate is only valid between two dots (for example, applying for `*.example.com`, the certificate cannot be used for `example.com` and `*.*.example.com`), it is necessary to apply for a [SAN](https://en.wikipedia.org/wiki/Subject_Alternative_Name) (Subject Alternative Name) wildcard certificate. According to the information on the Let's Encrypt official website, applying for a wildcard certificate requires DNS-01 verification. Here, we demonstrate how to apply for a free TLS certificate from Let's Encrypt using [acme.sh](https://acme.sh) for a domain with NS records hosted on Cloudflare. For the application method using other domain name hosting providers, please refer to [dnsapi · acmesh-official/acme.sh Wiki](https://github.com/acmesh-official/acme.sh/wiki/dnsapi).
|
||||
|
||||
|
||||
First, you need to go to the [Cloudflare dashboard](https://dash.cloudflare.com/profile/api-tokens) to create an API token. The parameters are as follows:
|
||||
|
||||
权限部分至关重要，其他部分任意。
|
||||
|
||||
|
||||
创建完毕后，你会得到一串神秘字符，请将其妥善保管到安全且不会丢失的地方，因为它不再会显示。这串字符就是即将用到的 `CF_Token`。
|
||||
The permission part is crucial, while other parts are optional.
|
||||
|
||||
::: tip 注意
|
||||
以下操作需要在 root 用户下进行，使用 sudo 会出现错误。
|
||||
After creating, you will receive a mysterious string of characters. Please keep it safe in a secure and non-losing place, as it will not be displayed again. This string of characters is the `CF_Token` that will be used soon.
|
||||
|
||||
::: tip Note
|
||||
The following operations need to be performed under the root user. Using sudo will result in errors.

||||

以上配置针对于 Nginx，以下是需要注意的一些细节。
|
||||
The above configuration is for Nginx. Here are some details that need to be noted.
|
||||
|
||||
- 有关 Proxy Protocol
|
||||
- About Proxy Protocol
|
||||
|
||||
Proxy Protocol 是 HaProxy 开发的一种旨在解决代理时容易丢失客户端信息问题的协议，常用于链式代理和反向代理。传统的处理方法往往较为复杂且有诸多限制，而 Proxy Protocol 非常简单地在传输数据时附带上原始连接四元组信息的数据包，解决了这个问题。
|
||||
Proxy Protocol is a protocol developed by HaProxy to solve the problem of easily losing client information during proxying. It is often used for chain proxying and reverse proxying. The traditional approach to handling this problem is often complex and has many limitations, while Proxy Protocol simply attaches the original connection quadruple information packet to the transmitted data, solving this problem in a very simple way.
|
||||
|
||||
凡事皆有利弊，Proxy Protocol 也是如此。
|
||||
Everything has its advantages and disadvantages, and the same goes for the Proxy Protocol.
|
||||
|
||||
- 有发送必须有接收，反之亦然
|
||||
- 同一端口不能既兼容带 Proxy Protocol 数据的连接又兼容不带数据的连接（如：Nginx 同端口的不同虚拟主机（server），本质是上一条）[^2][^3]
|
||||
- If there is sending, there must be receiving, and vice versa.
|
||||
- The same port cannot be compatible with connections that have Proxy Protocol data and those that don't have data (e.g., different virtual hosts (servers) on the same port in Nginx, which is essentially the previous point). [^2][^3]
|
||||
|
||||
在遇到异常时，请考虑配置是否符合上述条件。
|
||||
Please consider whether the configuration meets the above conditions when encountering exceptions.
|
||||
|
||||
此处，我们使用 Proxy Protocol 让被回落到的目标获取到客户端的真实 IP。
|
||||
Here, we use the Proxy Protocol to allow the fallback target to obtain the real IP address of the client.
|
||||
|
||||
另外，当 Xray 的某个入站配置存在 `"acceptProxyProtocol": true` 时，ReadV 将失效。
|
||||
In addition, when the `"acceptProxyProtocol": true` exists in a certain inbound configuration of Xray, ReadV will be invalidated.
|
||||
|
||||
- 有关 HTTP/2
|
||||
- Regarding HTTP/2
|
||||
|
||||
首先，`inbounds.streamSettings.tlsSettings.alpn` 有顺序，应将 `h2` 放前，`http/1.1` 放后，在优先使用 HTTP/2 的同时保证兼容性；反过来会导致 HTTP/2 在协商时变为 HTTP/1.1，成为无效配置。
|
||||
First, `inbounds.streamSettings.tlsSettings.alpn` has an order. `h2` should be placed before `http/1.1` to prioritize the use of HTTP/2 while ensuring compatibility. Placing them in reverse order will cause HTTP/2 to be negotiated as HTTP/1.1, resulting in an invalid configuration.
|
||||
|
||||
在上述配置中，每条回落到 Nginx 的配置都要分成两个。这是因为 h2 是强制 TLS 加密的 HTTP/2 连接，这有益于数据在互联网中传输的安全，但在服务器内部没有必要；而 h2c 是非加密的 HTTP/2 连接，适合该环境。然而，Nginx 不能在同一端口上同时监听 HTTP/1.1 和 h2c，为了解决这个问题，需要在回落中指定 `alpn` 项（是 `fallbacks` 而不是 `tlsSettings` 里面的），以尝试匹配 TLS ALPN 协商结果。
|
||||
In the above configuration, each `fallback` configuration that falls back to Nginx needs to be divided into two. This is because h2 is an HTTP/2 connection that requires TLS encryption, which is beneficial for the security of data transmission over the Internet, but is unnecessary within the server. On the other hand, h2c is a non-encrypted HTTP/2 connection that is suitable for this environment. However, Nginx cannot listen for HTTP/1.1 and h2c on the same port at the same time. To solve this problem, the `alpn` option (in `fallbacks` rather than `tlsSettings`) needs to be specified in the fallback to try to match the TLS ALPN negotiation result.
|
||||
|
||||
建议 `alpn` 项只按需用两种填法：[^4]
|
||||
Suggestion: Use only two types of fillings for the `alpn` item as needed: [^4]
|
||||
|
||||
- 省略
|
||||
- `"h2"`
|
||||
- Omitted
|
||||
- `"h2"`
|
||||
|
||||
如果使用 Caddy 就大可不必如此繁杂了，因为它**可以**在同一端口上同时监听 HTTP/1.1 和 h2c，配置改动如下：
|
||||
If you use Caddy, you don't need to be so complicated, because **it can** listen to HTTP/1.1 and h2c on the same port at the same time. The configuration changes are as follows:

# Enhancing Proxy Security with Cloudflare Warp
|

Xray（1.6.5+）新加入了 WireGuard 出站，虽然增加的代码和依赖会增大 core 体积，但是我们认为这是一个很有必要的新功能，原因有三：
|
||||
Xray (1.6.5+) has added outbound WireGuard support. Although the added code and dependencies will increase the core size, we believe that this is a necessary new feature for three reasons:
|
||||
|
||||
1. 通过近期的一些讨论和[实验](https://github.com/net4people/bbs/issues/129#issuecomment-1308102504)，我们知道代理回国流量是不安全的。一种应对方式是将回国流量路由至黑洞，它的缺点是由于 geosite 和 geoip 更新的不及时或者新手不知道如何在客户端适当分流，结果流量进入黑洞，影响使用体验。
|
||||
这时我们只需要将回国流量导入 Cloudflare Warp，可以在不影响使用体验的情况下达到同样的安全性。
|
||||
2. 众所周知，大部分机场会记录用户访问域名的日志，某些机场还会审计和阻断一些用户流量。保护用户私密性的一个方法，就是在客户端使用链式代理。
|
||||
Warp 使用的 WireGuard 轻量级 VPN 协议会在代理层内增加一层加密。对于机场而言，用户所有流量的目标都是 Warp，从而最大程度保护自己的隐私。
|
||||
3. 方便使用，只需要一个 core 即可完成分流，Wireguard Tun，链式代理的设置。
|
||||
1. Through recent discussions and [experiments](https://github.com/net4people/bbs/issues/129#issuecomment-1308102504), we know that proxying the traffic back to China is not safe. One way to deal with this is to route the back-to-China traffic to a black hole, but the downside is that due to the delay in geosite and geoip updates or the lack of knowledge on how to properly split the traffic on the client side, the traffic ends up going to the black hole, affecting the user experience. In this case, we only need to import the back-to-China traffic into Cloudflare Warp, which can achieve the same level of security without affecting the user experience.
|
||||
2. As we all know, most airports will log the domain names visited by users, and some airports will even audit and block some user traffic. One way to protect user privacy is to use chain proxies on the client side. The WireGuard lightweight VPN protocol used by Warp adds an extra layer of encryption within the proxy layer. For airports, the target of all user traffic is Warp, thereby maximizing privacy protection.
|
||||
3. It is easy to use, and only one core is needed to complete the split, Wireguard Tun, and chain proxy settings.
