安装php实现动态
[[email protected] ~]# yum install php -y
[[email protected] ~]# vim /var/www/html/index.php

测试172.25.135.1/index.php
[[email protected] haproxy]# vim haproxy.cfg

[[email protected] haproxy]# yum install httpd
[[email protected] haproxy]# vim /etc/httpd/conf/httpd.conf 改端口为8080
[[email protected] haproxy]# /etc/init.d/httpd restart
测试 172.25.135.1：8080
[[email protected] haproxy]# vim haproxy.cfg

测试：172.25.135.1/index.php #自动跳到baidu
[[email protected] haproxy]# vim haproxy.cfg

在server2和3上安装php下载upload
[[email protected] ~]# mv upload/ /var/www/html/
[[email protected] html]# chmod 777 upload/
[[email protected] upload]# mv * ..
[[email protected] html]# vim upload_file.php 将图片默认大小改到合适大小
[[email protected] html]# /etc/init.d/httpd restart #server3同操作
浏览器访问：172.25.135.1/index.php

上传图片则server2无文件server3有上传文件，从而实现读写分离。
[[email protected] html]# cd upload
[[email protected] upload]# ls
