2. keepalived的配置
　　配置server6的keepalived配置文件/etc/keepalived/keepalived.conf（/etc/keepalived/里面没有文件，需要新编辑一个）
　　
　　vi /etc/keepalived/keepalived.conf

bal_defs {

       notification_email {

              wuweina@tonglukuaijian.com

       }

       notification_email_fromwuweina@tonglukuaijian.com

       smtp_server 127.0.0.1

       smtp_connect_timeout 30

       router_id test1

}

vrrp_instance VI_1 {

       state MASTER

       interface eth1

       virtual_router_id 51

       priority 100

       advert_int 1

       smtp_alert

       authentication {

               auth_type PASS

               auth_pass 123

       }

       virtual_ipaddress {

               192.168.10.170

       }

}

　　server7的配置：
　　keepalived配置文件/etc/keepalived/keepalived.conf，内容如下：
　　vi /etc/keepalived/keepalived.conf

bal_defs {

       notification_email {

              wuweina@tonglukuaijian.com

       }

       notification_email_fromwuweina@tonglukuaijian.com

       smtp_server 127.0.0.1

       smtp_connect_timeout 30

       router_id test2

}

vrrp_instance VI_1 {

       state MASTER

       interface eth1

       virtual_router_id 51

       priority 80

       advert_int 1

       smtp_alert

       authentication {

               auth_type PASS

               auth_pass 123

       }
