今天使用rabbitmqctl指令报错：

Error: unable to perform an operation on node 'rabbit@bogon'. 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@bogon ?* If target node is configured to use long node names, don't forget to use --longnames with CLI tools

DIAGNOSTICS ===========

attempted to contact: [rabbit@bogon]

rabbit@bogon: ? * connected to epmd (port 4369) on bogon ? * epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic? ? * can't establish TCP connection to the target node, reason: timeout (timed out) ? * suggestion: check if host 'bogon' resolves, is reachable and ports 25672, 4369 are not blocked by firewall

Current node details: ?* node name: 'rabbitmqcli-3194-rabbit@bogon' ?* effective user's home directory: /var/lib/rabbitmq ?* Erlang cookie hash: 82cXRwkd79O7kK6IhnxJsA==

解决方案

1.查找自己的主机名

2.vim /etc/hosts

3.加入自己的ip 和主机名?

4.执行rabbitmqctl指令，可以执行了
