配置前需要保证nginx已经安装。

1. 打开/etc/nginx/nginx.conf文件
   末尾添加include proxy/*.conf;这一行
2. /etc/nginx/目录下创建proxy目录，并在proxy目录下创建tcp.py文件
   3.tcp.py文件加入以下代码

stream{
    upstream testtcp{
        hash $remote_addr consistent;
        server  127.0.0.1:8881 max_fails=3 fail_timeout=10s;  
        server  127.0.0.1:8882 max_fails=3 fail_timeout=10s;  
        server  127.0.0.1:8883 max_fails=3 fail_timeout=10s;  
        server  127.0.0.1:8884 max_fails=3 fail_timeout=10s;  
    }
    server{
        listen 8888;
        proxy_connect_timeout 20s;
        proxy_timeout 5m;
        proxy_pass testtcp;
    }
}
