nginx 配置4层代理

nginx-1.9.0 开始支持 TCP 代理，也就是4层代理，默认编译不会支持，需要加上 –with-stream 参数编译。

NGINX 编译

进入 nginx 目录

cd /home/fwj/nginx-1.15.9

编译

./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream

配置 nginx.conf

user  www www;
worker_processes  1;


events {
    worker_connections  1024;
}

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"';
    open_log_file_cache off;
    access_log logs/tcp-access.log proxy ;
    upstream test{
        server 127.0.0.1:666  weight=1 max_fails=1 fail_timeout=30s;
    }
    server{
        listen 60;
        proxy_pass test;
        proxy_connect_timeout 8s;
        proxy_timeout 7d;
    }
}

执行

./nginx -c /usr/local/nginx/conf/nginx.conf
