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 HTTPS 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;
    }
}

/etc/systemd/system 文件夹中创建 nginx.service 文件

vim /etc/systemd/system/nginx.service

写入如下

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network-online.target remote-fs.target nss-lookup.target
After=xray.service

[Service]
Type=forking

[Install]
WantedBy=multi-user.target

加入开机自启

systemctl enable nginx

                "outboundTag": "nginxtls"
            }
        ]
    }
}

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

结束

双端 Haproxy 构建 HTTPS 隧道隐藏指纹

安装 Haproxy

pacman -Su haproxyapt 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

网路结构:

xray_client ---tcp--- haproxy_client ---HTTPS--- haproxy_sever ---tcp--- xray_server

    # 域名或 IP 均可以,若填域名建议在 hosts 中指定 IP 降低解析时间;alpn 与服务器协商,服务器端为 alpn h2,http1.1 时,客户端指定为 h2 则隧道为 HTTP2 方式连接,指定为 http1.1 为 HTTP 方式,双端均写优先 h2

backend web
    server web /dev/shm/h1h2c.sock # 回落到网页

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

haproxy_client 配置

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

backend web

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
