1、服务器环境：centos7.5

2、安装nginx

首先下载：wget http://nginx.org/download/nginx-1.14.0.tar.gz

解压：tar zxvf  nginx-1.14.0.tar.gz得到解压包nginx-1.14.0

进入nginx-1.14.0，执行编译命令：./configure  --with-stream --without-http

(注意：要系统支持c编译环境，安装方法yum -y install gcc gcc-c++)

make 

make install

3、修改配置文件，nginx默认安装路径：/usr/local/nginx

vim /usr/local/nginx/conf/nginx.conf，内容如下：

#user nobody;

worker_processes 1;

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid;

events {

#use epoll;

worker_connections 1024;

}

stream {

  upstream socket{

  server 192.168.1.155:8000;

  server 192.168.1.154:8000;

}

server {

  listen 80;

  proxy_pass socket;

}

} 

4、启动：/usr/local/nginx/sbin/nginx

　  停止：/usr/local/nginx/sbin/nginx -s stop

     退出：/usr/local/nginx/sbin/nginx -s quit

     重启：/usr/local/nginx/sbin/nginx -s reload
