HAProxy实现动静分离和负载均衡

由于电脑配置渣，带不动多台虚拟机，所以采用httpd虚拟主机的方式来实现

1 2 3

CentOS 6.7 httpd: 2.2.15 HAProxy: 1.5.4

主机规划

1 2 3 4 5

- 172.18.1.49:8080 -->web server1 - 172.18.1.49:8081 -->web server2 - 172.18.1.49:8088 -->app server1 - 172.18.1.49:8089 -->app server2 -

• 网站资源根目录定义在/data/下

配置虚拟主机

安装httpd及PHP

1 2	yum install httpd php -y yum install haproxy -y

修改httpd主机监听的端口

1 2 3 4 5 6 7

# 注释掉80 Listen 8080 Listen 8081 Listen 8088 Listen 8089 #DocumentRoot "/var/www/html" # 注释掉此行

配置虚拟主机websrv1

注意：CentOS7默认安装的是Httpd2.4+,所以，在配置虚拟主机时，allow from all要改为Require all granted

1 2 3 4 5 6 7 8 9

vim /etc/httpd/conf.d/websrv1.conf DirectoryIndex index.html <virtualhost 172.18.1.49:8080> DocumentRoot /data/webdoc1/ <directory "/data/webdoc1"> allow from all # apache2.4版本要改为Require all granted，下同！ </directory> </virtualhost>

配置虚拟主机websrv2

1 2 3 4 5 6 7 8 9

vim /etc/httpd/conf.d/websrv2.conf DirectoryIndex index.html <virtualhost 172.18.1.49:8081> DocumentRoot /data/webdoc2/ <directory "/data/webdoc2"> allow from all </directory> </virtualhost>

配置虚拟主机appsrv1

vim /etc/httpd/conf.d/app1.conf DirectoryIndex index.php <virtualhost 172.18.1.49:8088> DocumentRoot /data/appdoc1/ <directory "/data/appdoc1"> allow from all </directory> </virtualhost>

配置虚拟主机appsrv2

1 2 3 4 5 6 7 8 9

vim /etc/httpd/conf.d/app2.conf DirectoryIndex index.php <virtualhost 172.18.1.49:8089> DocumentRoot /data/appdoc2/ <directory "/data/appdoc2"> allow from all </directory> </virtualhost>

为各主机提供测试页

vim /data/webdoc1/index.html <h1>web-server1</h1> #websrv2 vim /data/webdoc2/index.html <h1>web-server2</h1> #appsrv1 vim /data/appdoc1/index.php <h1>app-server1</h1> <?php phpinfo(); ?> #appsrv2 vim /data/appdoc2/index.php <h1>app-server2</h1> <?php phpinfo(); ?>
