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 http://nginx.org/download/nginx-1.12.1.tar.gz

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.conf
worker_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
