Centos7 haproxy動靜分離

實現的結果：
當客戶端訪問haproxy時，請求的是靜態檔案內容時，請求轉交給static server，請求的是php內容時，請求轉交給php server，請求的是jsp內容時，請求轉交給tomcat server，以實現動靜分離。
haproxy伺服器:192.168.80.100
先部署三臺web伺服器：
一臺httpd支援php 192.168.80.101
一臺部署httpd支援靜態資源 192.168.80.102
一臺tomcat支援jsp 192.168.80.103

192.168.80.100:
1、安裝編譯環境與軟體
yum install -y pcre-devel bzip2-devel gcc gcc-c++ make

2、原始碼編譯安裝haproxy
tar xzvf haproxy-1.5.15.tar.gz -C /opt

cd /opt/haproxy-1.5.15
make TARGET=linux26  PREFIX=/usr/local/haproxy     //標識64為系統
make install PREFIX=/usr/local/haproxy

3、配置haproxy配置檔案
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

yum install -y php

2、安裝php外掛

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、修改配置檔案

vi /etc/httpd/conf/httpd.conf
ServerName www.aa.com
DirectoryIndex index.html index.php

vi /etc/php.ini
date.timezone = PRC    日期時區=×××
 

4、建立一個php網頁

cd  /var/www/html
vi index.php
<?php
phpinfo();
?>

systemctl start httpd

瀏覽器輸入:192.168.80.101

yum install httpd -y

2、安裝上傳軟體
yum install lrz* -y

3、修改配置檔案

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

4、建立一個img目錄，在給img目錄裡放進去一張圖片，在建立一個index.html網頁

cd  /var/www/html
mkdir img
放進入一張圖片，找一張圖片直接拉到Xshell
cd ..
vi  index.html
<h1>靜態</h1>

systemctl start httpd
瀏覽器輸入:192.168.80.102
192.168.80.102/img/圖片名稱.格式

192.168.80.103:
軟體包自己去網上找
1、安裝JAVA
tar xf jdk-8u144-linux-x64.tar.gz

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

vi /etc/profile //在檔案末尾新增

export JAVA_HOME=/usr/local/java  安裝路徑
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、安裝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

瀏覽器輸入:192.168.80.103:8080

測試：瀏覽器中輸入
192.168.80.100:8089/status 統計頁面

瀏覽器中輸入:192.168.80.100/index.php

192.168.80.100/img/圖片名稱.格式

192.168.80.100/index.jsp
