在虚拟机上刚装完Oracle RAC，重新启动系统后。重新启动了oracle所有的服务，一开始所有的服务都正常。
但是过了一会，节点2的vip又再次飘移到了节点1上，并且节点2的监听服务也OFFLINE了。反复启动了几次都是同样的效果的。
[root@node2 bin]# ./crs_stat -t

节点2上的监听没有起，并且节点2的vip起在节点1上。之前监听器是在节点1上建立的一个集群监听。
尝试将节点2的vip停止下来再重新启动，发现只能在节点1上启动。
/u01/app/oracle/crs/log/node2/crsd/crsd.log的日志报错：

将所有服务都停止，然后一一重启就好了。
