故障：keepalived启动时vip 没有生成

问题说明：

keepalived已启动但vip 没有生成。/var/log/messages日志不断刷屏

 

tail /var/log/messages 

Nov  3 11:51:03 cache-redis-01 Keepalived_vrrp[1269]: (redis): ip address associated with VRID 53 not present in MASTER advert : 172.16.1.63
Nov  3 11:51:03 cache-redis-01 Keepalived_vrrp[1269]: bogus VRRP packet received on eth0 !!!
Nov  3 11:51:03 cache-redis-01 Keepalived_vrrp[1269]: VRRP_Instance(redis) ignoring received advertisment...

 

问题分析及解决方案：

1、两条主机的时间不同，将两台主机时间改为一致即可。

2、virtual_router_id 设置有问题，修改一下其他数字试试。

3、vrrp的优先级设置有问题，默认设备故障会自动降10，所以差值不要超过10。
