初次配置LVS+Keepalived，

vip:172.16.10.8
dr2:172.16.10.9 BACKUP
dr1:172.16.10.10 MASTER
rip1:172.16.10.11
rip2:172.16.10.12
已上IP可以互PING通

配置文件如下：
[root@DR1 keepalived]# cat keepalived.conf
! Configuration File for keepalived

global_defs {
notification_email {
   acassen@firewall.loc
   failover@firewall.loc

}

      }
}
real_server 172.16.10.12 80 {

      }
}
}
[root@DR1 keepalived]#
keepalived启动正常，但是只有一个真实主机可以被成功添加。

问题：
为什么只有第一个REAL SERVER被添加到列表中，另一台确没有被添加成功！
请前辈们给看一下是怎么回事。
谢谢啦
