配置Apache Http服务
1、三个节点配置 /etc/httpd/conf/httpd.conf
[root@controller1 ~] # vim /etc/httpd/conf/httpd.conf
ServerName controller1
Listen 8080
[root@controller2 ~]# vim /etc/httpd/conf/httpd.conf
ServerName controller2
Listen 8080
[root@controller3 ~]# vim /etc/httpd/conf/httpd.conf
ServerName controller3
Listen 8080
2、[root@controller1 ~]# vim /etc/httpd/conf.d/wsgi-keystone.conf
<VirtualHost *:5000>
