controller控制节点重启nova相关服务启动失败

重启三节点的openstack

启动好了查看nova服务如上，日志如下：
2015-04-13 20:45:27.073 1036 TRACE nova.openstack.common.threadgroup OperationalError: (OperationalError) (2003, "Can't connect to MySQL server on 'controller' (111)") None None
2015-04-13 20:45:27.073 1036 TRACE nova.openstack.common.threadgroup

查看mysql状态是开着的

计算节点的nova-compute查看状态已经开了，日志如下

2015-04-13 20:49:43.358 2500 WARNING nova.openstack.common.loopingcall [-] task <bound method DbDriver._report_state of <nova.servicegroup.drivers.db.DbDriver object at 0x7f249566e810>> run outlasted interval by 50.02 sec

之后手动重启
  353  service nova-cert start
  355  service nova-scheduler start
  357  service nova-conductor start
  358  nova service-list
计算节点
root@compute1:~# service nova-compute restart

然后查看就OK了，不知道是什么原因，开机也显示服务全是OK    mysql启动慢了吗？
