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

CentOS 6.7


httpd: 2.2.15


HAProxy: 1.5.4

- 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

# 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
