2023最新版本xray搭建：通过SNI实现vless和vmess协议共存及443端口复用搭建网站-深圳seo欢欢

背景： v2ray的vmess本身是一款稳定、安全的协议，在稳定安全的基础上，大家还会对速度和性能有更高的追求。在此背景下，诞生了Trojan及vless之类的协议，vless的实现思想和trojan类似。而xray是在v2ray-core的基础上实现了vmess和vless的功能合集，而且还增加对xtls的支持。

像trojan的设计是直接使用HTTPS通信，会占用443端口，如果你的VPS服务器除了科学上网工具，还同时搭建了网站的话，这就会产生冲突。

今天这个xray的搭建教程，是通过SNI回落的方式，来实现将xray的vless使用443端口，作为统一的网络通信入口。80端口会跳转到443端口。然后通过SNI回落，来将不同域名及协议进行分流：也就是vmess协议的流量，会回落到vmess的监听端口；网站对应的域名，会回落到网站对应的端口地址。从而实现vless、vmess、网站共存，443端口复用的目的。

结果预期：

可实现vless协议的代理服务；
可实现vmess协议的代理服务；
可通过443端口来实现网站服务的正常访问；

v2ray搭建脚本说明

使用到的安装脚本，是xray社区的官方脚本：https://github.com/XTLS/Xray-install；该脚本在执行时会提供info和error 等信息，请仔细查看执行过程中打印的信息。

简要使用：

安装和更新xray-core及geodata

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install -u root

只安装xray-core，不安装geodata

// 只更新 .dat 資料檔
bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install --without-geodata

移除/卸载xray

# bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ remove --purge

环境信息

系统：Debian GNU/Linux 10
这里使用的root用户
xray-core版本：v1.5.4，地址：https://github.com/XTLS/Xray-core/releases ;
v2rayN：5.9，地址：https://github.com/2dust/v2rayN/releases ；

开始搭建

下面我搭建过程中涉及的域名your-domain.com，请在实际执行过程中，换成你自己的域名。

1 连接VPS

这篇文章里有使用xshell远程连接VPS的细节。

2 更新VPS环境

apt update

3 安装curl

apt install -y curl

4 安装xray

使用curl进行安装

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install -u root

上面的脚本执行日志的细节如下：

从日志里，我们可以看到安装使用的配置文件信息：/usr/local/etc/xray/config.json。

5 安装nginx

执行安装

apt install -y nginx

新建网页目录

这里在假设是/root/www。

mkdir -p /root/www

新建首页

在/root/www目录下新建一个index.html文件，

vi /root/www/index.html

内容如下：

<html>
   <title>欢迎访问四个空格</title>
   <head><meta charset="UTF-8"></head>
   <body>
     <a href="https://www.4spaces.org/install-v2ray-v-4-44-on-debian-2022/">四个空格</a>
   </body>
</html>

新建配置文件

注：不同版本的nginx配置文件可能有区别，我的是nginx/1.18.0，配置文件/etc/nginx/sites-enabled/default。或者你的配置文件可能在/etc/nginx/conf.d/default.conf。

输入vi /etc/nginx/sites-enabled/default命令，编辑nginx配置文件为如下内容：

server{
    listen 80;
    server_name www.your-domain.com your-domain.com blog.your-domain.com;
    index index.html;
    root /root/www/;
}

这里你可能需要将/etc/nginx/nginx.conf中第一行user www-data改为user root，即当前用户。

启动nginx服务

#启动Nginx并设置为开机自启
systemctl start nginx;systemctl enable nginx

#查看nginx启动状态
systemctl status nginx

说明：配置文件中，www.your-domain.com、your-domain.com作为网站域名使用，通过443端口作为入口，在xray回落配置里，域名分流指向网站目录。而blog.your-domain.com是根据vmess协议分流到代理服务端口。

在浏览器里访问your-domain.com，如果正常则说明nginx配置没问题，这是是没有加密的，不带HTTPS的网址：http://www.your-domain.com。

6.6 安装certbot并申请ssl证书

具体如下：

安装snapd

apt install -y snapd

确保snapd为最新版本

snap install core; snap refresh core

安装certbot

snap install --classic certbot

创建软链

ln -s /snap/bin/certbot /usr/bin/certbot

申请证书

运行certbot --nginx开始申请证书，申请时，选择为多个域名申请证书时，各域名对应数字用英文逗号或空格分隔，如下：

如上图，执行过程中出现Successfully received certificate表示获取证书成功，并显示了证书的保存路径。

Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/your-domain/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/your-domain/privkey.pem
This certificate expires on 2022-07-20.

6.7 更改Nginx和xray配置文件信息

xray配置

将/usr/local/etc/xray/config.json更改为以下内容：

{
    "log": {
        "loglevel": "warning",
    "access": "/var/log/xray/access.log",
        "error": "/var/log/xray/error.log"
    },
    "inbounds": [{
            "port": 443,
            "protocol": "vless",
            "settings": {
                "clients": [{
                        "id": "e2b89a7a-6a6b-47f1-9e17-09c6d1e5a746",
                        "flow": "xtls-rprx-direct"
                    }
                ],
                "decryption": "none",
                "fallbacks": [{
                        "name": "blog.your-domain.com",
                        "path": "/vmessws",
                        "dest": 6000,
                        "xver": 1
                    }, {
                        "dest": 6001,
                        "xver": 1
                    }, {
                        "alpn": "h2",
                        "dest": 6002,
                        "xver": 1
                    }, {
                        "name": "your-domain.com",
                        "dest": 6003,
                        "xver": 1
                    }, {
                        "name": "your-domain.com",
                        "alpn": "h2",
                        "dest": 6004,
                        "xver": 1
                    }
                ]
            },
            "streamSettings": {
                "network": "tcp",
                "security": "xtls",
                "xtlsSettings": {
                    "alpn": [
                        "h2",
                        "http/1.1"
                    ],
                    "certificates": [{
                            "certificateFile": "/etc/letsencrypt/live/your-domain.com/fullchain.pem",
                            "keyFile": "/etc/letsencrypt/live/your-domain.com/privkey.pem"
                        }
                    ]
                }
            }
        }, {
            "port": 6000,
            "listen": "127.0.0.1",
            "protocol": "vmess",
            "settings": {
                "clients": [{
                        "id": "2f726dac-6a7a-430d-8870-fb5634cf500c"
                    }
                ]
            },
            "streamSettings": {
                "network": "ws",
                "wsSettings": {
                    "acceptProxyProtocol": true,
                    "path": "/vmessws"
                }
            }
        }
    ],
    "outbounds": [{
            "protocol": "freedom"
        }
    ]
}

将上面的域名换成自己的域名。

nginx配置

配置文件/etc/nginx/site-enabled/default：

set_real_ip_from 127.0.0.1;
real_ip_header proxy_protocol;


server {
    listen 127.0.0.1:6001 proxy_protocol default_server;
    listen 127.0.0.1:6002 proxy_protocol default_server http2;
    index index.html;
    root /root/www/;
}


server {
    listen 127.0.0.1:6003 proxy_protocol;
    listen 127.0.0.1:6004 proxy_protocol http2;

    server_name your-domain.com;
    index index.html;
    root /root/www/;
}

server{
    if ($host = www.your-domain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = blog.your-domain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = your-domain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    server_name www.your-domain.com your-domain.com blog.your-domain.com;
    return 404; # managed by Certbot

}

重启xray及nginx服务

#重启xray
systemctl restart xray

#重启nginx
systemctl restart nginx

至此xray的搭建完成。

6.8 客户端v2rayN配置

vless协议配置大体截图：

使用vmess协议链接的配置截图：

Cloudflare要不要启用CDN？

启用后比较慢，针对国内，作用可能会隐藏真实IP，除非IP被墙，大概率你是不需要启用的。
