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

192.168.80.101:
1、安装php
yum install -y php

2、安装php插件

yum install -y php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash

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
vi index.php
<?php
phpinfo();
?>

systemctl start httpd

浏览器输入:192.168.80.101

yum install httpd -y

2、安装上传软件
yum install lrz* -y

3、修改配置文件

vi /etc/httpd/conf/httpd.conf
ServerName www.aa.com

4、创建一个img目录，在给img目录里放进去一张图片，在创建一个index.html网页

cd  /var/www/html
mkdir img
放进入一张图片，找一张图片直接拉到Xshell
cd ..
vi  index.html
<h1>静态</h1>

systemctl start httpd
浏览器输入:192.168.80.102
192.168.80.102/img/图片名称.格式

cp -rv jdk1.8.0_144/ /usr/local/java

vi /etc/profile //在文件末尾新增

export JAVA_HOME=/usr/local/java  安装路径
export JRE_HOME=/usr/local/java/jre
export PATH=$PATH:/usr/local/java/bin
export CLASSPATH=./:/usr/local/java/lib:/usr/local/java/jre/lib

source /etc/profile

2、安装tomcat

cp -r apache-tomcat-8.5.23 /usr/local/tomcat8

ln -s /usr/local/tomcat8/bin/startup.sh /usr/bin/tomcatup
