Error: unable to perform an operation on node 'rabbit@localhost'. 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 https://rabbitmq.com/documentation.html to learn more
* Consult server logs on node rabbit@localhost
* If target node is configured to use long node names, don't forget to use --longnames with CLI tools
DIAGNOSTICS
===========
attempted to contact: [rabbit@localhost]
rabbit@localhost:
* connected to epmd (port 4369) on localhost
* epmd reports: node 'rabbit' not running at all
no other nodes on localhost
* suggestion: start the node
Current node details:
* node name: 'rabbitmqcli-232-rabbit@localhost'
* effective user's home directory: /var/lib/rabbitmq
* Erlang cookie hash: f6FBQkwOCP/Ifjkkf8mVkw==
解决办法:
查找 .erlang.cookie的位置
find / -name .erlang.cookie
/home/efc/.erlang.cookie /var/lib/rabbitmq/.erlang.cookie
把两个文件中的内容改为一致, 重启 rabbitmq 即可
systemctl restart rabbitmq-server
