Nginx1.9 版本以后增加 stream模块，可以对tcp，udp请求进行代理和负载均衡了

1、安装

yum -y install pcre-devel

wget

tar zxf nginx-1.12.1.tar.gz

cd nginx-1.12.1

./configure --prefix=/usr/local/nginx --with-stream --with-stream_ssl_module

make

make install

2、配置

#vim /usr/local/nginx/conf/nginx.confworker_processes auto;error_log /usr/local/nginx/logs/error.log error;events { worker_connections 1024;}stream { log_format main '$remote_addr [$time_local]'' $protocol $status $bytes_sent $bytes_received''$session_time $upstream_addr $upstream_bytes_sent''$upstream_bytes_received $upstream_connect_time';upstream backend { #hash $remote_addr consistent;least_conn;server 127.0.0.8:50179;server 127.0.0.9:50179;server 127.0.0.248:50179;server 127.0.0.249:50179;server 127.0.0.32:50179;server 127.0.0.33:50179;server 127.0.0.34:50179;server 127.0.0.35:50179;server 127.0.0.36:50179;server 127.0.0.8:50179;}

server {    listen 1080;    access_log /usr/local/nginx/logs/access.log main;    proxy_pass backend;}

}

3、启动：

/usr/local/nginx/sbin/nginx
