Nginx做反向代理转发socket的TCP请求

1、socket使用的是TCP/IP协议，编译安装nginx必须启用--with-stream模块。在stream中配置请求转发

./configure  [--prefix=/usr/local/nginx：指定安装目录】  --with-stream 

make

make install 

2、在配置文件nginx.conf中加stream模块

worker_processes  1;
events {
    worker_connections  1024;
}
# 此为TCP转发请求 stream
stream {
  log_format proxy '$remote_addr - [$time_local] '
                 '$protocol $status $bytes_sent $bytes_received '
                 '$session_time "$upstream_addr" '
                 '"$upstream_bytes_sent" "$upstream_bytes_received"                 
                 "$upstream_connect_time" '
                 '$remote_addr $remote_port $server_addr $server_port';

     include ./conf.d/*.tcpstream;

    # 后端指向 server 的 8085 端口 stream_backend 组
    upstream stream_backend {
         server 10.50.2.11:8085;
         server 10.50.2.19:8085;
    }
    # 后端指向 server 的 8090 端口 cns组
    upstream cns {
         server 10.50.2.11:8090;
         server 10.50.2.19:8090;
    }
  server {
        # 本机监听端口 8080
        listen                8080;
        # 请求抛给 stream_backend 组
        proxy_pass            stream_backend;
        access_log logs/host.access.log proxy;
       }
  server {
        # 本机监听端口 8090
        listen                8090;
        # 请求抛给 cns 组
        proxy_pass            cns;
        access_log logs/host.access.log proxy;
       }
}
    # 此为HTTP 转发请求 http
    http {

        gzip_vary on;
