Centos7 haproxy动静分离

实现的结果:
当客户端访问haproxy时,请求的是静态文件内容时,请求转交给static server,请求的是php内容时,请求转交给php server,请求的是jsp内容时,请求转交给tomcat server,以实现动静分离。
haproxy服务器:192.168.80.100
先部署三台web服务器:
一台httpd支持php 192.168.80.101
一台部署httpd支持静态资源 192.168.80.102
一台tomcat支持jsp 192.168.80.103

192.168.80.100:
1、安装编译环境与软件
yum install -y pcre-devel bzip2-devel gcc gcc-c++ make

2、源码编译安装haproxy
tar xzvf haproxy-1.5.15.tar.gz -C /opt

cd /opt/haproxy-1.5.15
make TARGET=linux26  PREFIX=/usr/local/haproxy     //标识64为系统
make install PREFIX=/usr/local/haproxy

3、配置haproxy配置文件
mkdir /etc/haproxy

useradd -s /sbin/nologin -M haproxy

cp /opt/haproxy-1.5.15/examples/haproxy.cfg /etc/haproxy/

vi /etc/haproxy/haproxy.cfg

3、修改配置文件

vi /etc/httpd/conf/httpd.conf
ServerName www.aa.com
DirectoryIndex index.html index.php
vi /etc/php.ini
date.timezone = PRC    日期时区=×××

4、创建一个php网页

cd  /var/www/html
