1.今天早上收到keealived报警信息，0.114上的keepalived挂了，在日志中看了一下，看到如下信息！

keepalived挂掉的服务器日志信息如下：

2.接管keepalived服务的主机服务如下：

Jun 20 08:12:20 localhost Keepalived_vrrp[527]: VRRP_Instance(VI_2) Transition to MASTER STATE
Jun 20 08:12:20 localhost Keepalived_vrrp[527]: VRRP_Instance(VI_4) Transition to MASTER STATE
Jun 20 08:12:20 localhost Keepalived_vrrp[527]: VRRP_Instance(VI_6) Transition to MASTER STATE

Jun 20 08:12:21 localhost avahi-daemon[2543]: Registering new address record for 192.168.0.225 on em1.IPv4.

再上cacti观察，发现8:12分的流量，CPU,负载都没有过大或者奇怪的现象，所以很难解释这个问题发生的原因是如何造成的。

等后续分析数据库日志看看有没有什么结论!
