Posted 2020-08-22

实验规划:

主机名	IP地址	角色
node01	192.168.112.128	web01
node02	192.168.112.129	web02
node03	192.168.112.130	haproxy

操作系统信息:

[[email protected] ~]# cat /etc/redhat-release 

CentOS release 6.6 (Final)

[[email protected] ~]# uname -a

Linux node03 2.6.32-504.el6.x86_64 #1 SMP Wed Oct 15 04:27:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

安装haproxy:

[[email protected] ~]# yum -y install haproxy nginx php

安装nginx php:

[[email protected] ~]# yum -y install nginx

[[email protected] ~]# yum -y install nginx

node01和node02上nginx配置文件:
