Nginx 或 Haproxy 实现的 HTTPS 隧道、HTTP/2 over HTTPS 隧道、WebSocket over HTTP/2 over HTTPS 隧道、gRPC over HTTP/2 over HTTPS 隧道以及自签证书双端认证的 gRPC over HTTP/2 over HTTPS 隧道
客户端服务端 Nginx 构建 HTPPS 隧道隐藏指纹
网路结构：
xray_client ---tcp--- nginx_client ---HTTPS--- nginx_sever ---tcp--- xray_server
编译 nginx --with-stream
在客户端及服务端均编译
curl -O -L http://nginx.org/download/nginx-1.22.1.tar.gz
tar -zxvf nginx-1.22.1.tar.gz
cd nginx-1.22.1
apt install gcc make //编译依赖 gcc 以及 make
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_v2_module --with-stream --with-stream_ssl_module //此步需要依赖一些库，根据报错安装相应 lib
make && make install
编译之后 nginx 文件夹位于 /usr/local/nginx
配置 nginx
编辑 nginx 配置文件 nginx.conf
vim /usr/local/nginx/conf/nginx.conf
服务端加入如下配置
服务器申请证书不再赘述，参考白话文
stream {
server {
listen 443 ssl;
listen [::]:443 ssl;
ssl_protocols TLSv1.3;
ssl_certificate /path/to/cert/domain.crt; # crt 文件位置
ssl_certificate_key /path/to/cert/domain.key; # key 文件位置
proxy_pass unix:/dev/shm/vless.sock; # 使用 domain socket
}
}
注意
stream 部分与 http 模块并列，客户端可删除 http 部分，服务端可删除或搭建网页伪装回落
客户端加入如下配置
stream {
server {
listen 6666;
listen [::]:6666;
proxy_ssl on;
proxy_ssl_protocols TLSv1.3;
proxy_ssl_server_name on;
proxy_ssl_name yourdomain.domain; # 服务器域名
proxy_pass ip:443; # 服务器 ip 形如 proxy_pass 6.6.6.6:443; 或 proxy_pass [2401:0:0::1]:443;
}
}
在 /etc/systemd/system 文件夹中创建 nginx.service 文件
vim /etc/systemd/system/nginx.service
写入如下

如果使用透明代理需要在 iptables 或 ip6tables 配置中加入
# 设置策略路由 v4
ip rule add fwmark 1 table 100
ip route add local 0.0.0.0/0 dev lo table 100
# 设置策略路由 v6
ip -6 rule add fwmark 1 table 106
ip -6 route add local ::/0 dev lo table 106
# VPS IP 直连
iptables -t mangle -A XRAY_MASK -d VSP_IPv4/32 -j RETURN
ip6tables -t mangle -A XRAY6_MASK -d VPS_IPv6/128 -j RETURN
客户端及服务端启动服务
systemctl restart xray
systemctl restart nginx

双端 Haproxy 构建 HTPPS 隧道隐藏指纹
安装 Haproxy
pacman -Su haproxy 或 apt install haproxy
Haproxy 处理 ssl 需要 openssl 支持，检查 openssl 版本，必要时安装或更新
HTTPS 隧道
前述 Nginx HTTPS 隧道 Hproxy 同样可以简单做到

xray 配置
同上 nginx 部分：最简单的 TCP 配置，可搭配任意协议，建议使用 VLESS+TCP 无需多余加密，参考文档或其他示例
WebSocket over HTTP/2
Haproxy 支持 HTTP/2 的 h2c 进站及出站
然而援引 xray 文档 HTTP/2 的说明
“由 HTTP/2 的建议，客户端和服务器必须同时开启 TLS 才可以正常使用这个传输方式。...... 当前版本的 HTTP/2 的传输方式并不强制要求入站（服务端）有 TLS 配置。”
即入站可以使用 h2c，出站并不支持 h2c。因此无法使用 xray_client ---h2c--- haproxy_client ---HTTP/2+TLS--- haproxy_sever ---h2c--- xray_server
但是可以通过 ws 偷个鸡，Haproxy 支持 ws over HTTP/2
则网络结构：xray_client ---ws--- haproxy_client ---ws over HTTP/2 over HTTPS--- haproxy_sever ---ws--- xray_server

xray 配置
简单的 websocket 配置即可，无需 TLS， 配置见 xray 文档示例，配置 "path" 可以用于服务端 haproxy 分流（客户端有分流需求同样可以通过客户端 haproxy 进行，原理类似，参考服务端的 path 分流配置）
gRPC over HTTP/2
虽然双端的 h2c 不行，但是 gRPC 不要求必须 TLS，直接冲

xray 配置
简单的 gRPC 配置，无需 TLS，配置见文档，配置的 serviceName 可用于分流。
Haproxy 使用自签证书进行双端认证（gRPC 示例）
这里使用自签证书双端认证加强隧道安全性（但会牺牲一点延迟，不过使用 gRPC 后感知不强），而服务端同时处理信任的证书和自签名证书，并据此分流伪装网站和隧道流量
其中 www.example.com 为伪装站信任证书（如白话文中申请的证书）
tunnel.example.com 为自签证书网址，自签证书可以参考 https://learn.microsoft.com/zh-cn/azure/application-gateway/self-signed-certificates
根证书 ca.crt 服务器证书 server.crt 服务器密钥 server.key
至少需要生成一个 server.pem，客户端可以同样使用此证书用于双端认证；或者生成两个证书，一个 client，一个 server，用于双端认证
需准备 fullchain.crt 用于认证（ cat server.crt ca.crt > fullchain.crt ），server.pem （ cat server.crt server.key ca.crt > server.pem ）用于解密
