执行rabbitmqctl相关指令报如下错误。查了一遍百度， 都是cookie的问题， 但是呢， 并没有没给出linux相关的解决文案, 折腾了很久
然后重启， 于是解决了
只是用户丢失了>>>>
不知道什么原因导致的
Status of node rabbit@k8s-node-heye-27 …
Error: unable to perform an operation on node ‘rabbit@k8s-node-heye-27’. Please see diagnostics information and suggestions below.
Most common reasons for this are:
* Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
* CLI tool fails to authenticate with the server (e.g. due to CLI tool’s Erlang cookie not matching that of the server)
* Target node is not running
In addition to the diagnostics info below:
* See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
* Consult server logs on node rabbit@k8s-node-heye-27
