C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin>rabbitmqctl list_queues
Error: unable to perform an operation on node ‘rabbit@xxxxxxx‘.
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@xxxxxxx
DIAGNOSTICS ===========
attempted to contact: [rabbit@xxxxxxx]
rabbit@xxxxxxx:
* connected to epmd (port 4369) on B62B562G5YL36KA
* epmd reports node ‘rabbit‘ uses port 25672 for inter-node and CLI tool traffic
* TCP connection succeeded but Erlang distribution failed
* Authentication failed (rejected by the remote node), please check the Erlang cookie
Current node details:
* node name: rabbitmqcli46@xxxxxxx
* effective user‘s home directory: C:\Users\Administrator
* Erlang cookie hash: D+xLmf+NlPkE9AReiKUnRw==
解决方法，如果服务启动了将C:\Windows\system32\config\systemprofile\.erlang.cookie中的.erlang.cookie拷贝到你的effective user‘s home directoryC:\Users\Administrator 下面。
