Error: unable to connect to node 'rabbit@devlop-ceilo': nodedown

在安装完成rabbitmq的时候,运行修改密码的指令rabbitmqctl change_password guest 123456
出现如下问题:

   Changing password for user "guest" ...   Error: unable to connect to node 'rabbit@devlop-ceilo': nodedown   DIAGNOSTICS    nodes in question: ['rabbit@devlop-ceilo']    hosts, their running nodes and ports:    - devlop-ceilo: [{rabbitmqctl4170,57110}]    current node details:    - node name: 'rabbitmqctl4170@devlop-ceilo'    - home dir: /var/lib/rabbitmq    - cookie hash: LOV2sNIqVbVpplwE+BDftg==

解决办法重启服务就解决：

service rabbitmq-server restart
