keepalive+nginx搭建主从负载服务器

keepalive配置文件 从：

1. ! Configuration File for keepalived

2. global_defs {

4.   xuezm@yaoshi.com

5.        }

6.   notification_email_from xuezm@yaoshi.com

7.   smtp_server mail.yaoshi.com

8.   smtp_connect_timeout 30

9.   router_id LVS_DEVEL

10. }

11. vrrp_instance VI_1 {

12.    state MASTER
