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
192.168.80.102: 1、安装httpd
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
静态
systemctl start httpd
浏览器输入:192.168.80.102
192.168.80.102/img/图片名称.格式
192.168.80.103:
1、配置JDK
tar xf jdk-8u144-linux-x64.tar.gz
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
ln -s /usr/local/tomcat8/bin/shutdown.sh /usr/bin/tomcatdown
tomcatup
netstat -anpt | grep 8080
浏览器输入:192.168.80.103:8080
测试：浏览器中输入
192.168.80.100:8089/status 统计页面
浏览器中输入:192.168.80.100/index.php
192.168.80.100/img/图片名称.格式
192.168.80.100/index.jsp
