RabbitMQ 错误解决

1.安装好mq后，查看状态，错误

S D:\RabbitMQ Server\rabbitmq_server-3.7.0\sbin> .\rabbitmqctl status

Status of node rabbit@DESKTOP-ECFDCQB ...

Error: unable to perform an operation on node 'rabbit@DESKTOP-ECFDCQB'. 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 to learn more

* Consult server logs on node rabbit@DESKTOP-ECFDCQB
