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 -
|
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
| Listen 8080 Listen 8081 Listen 8088 Listen 8089
|
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
1 2
| 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
| 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(); ?>

修改HAProxy配置
