linux centos7 环境下rabbitmqctl status报错

问题：

[[email protected] rabbitMq]# rabbitmqctl  list_users
Error: unable to perform an operation on node '[email protected]'. 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 [email protected]
 * If target node is configured to use long node names, don't forget to use --longnames with CLI tools

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

attempted to contact: [[email protected]]

[email protected]:
  * 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: '[email protected]'
 * effective user's home directory: /var/lib/rabbitmq
 * Erlang cookie hash: mVWZ9hzwnH+BCsNzXPPxQA==

解决办法：

    问题出在 “”Error: unable to perform an operation on node '[email protected]'

在 /etc/hosts 文件做一个映射，就将hostname  bogon与本机ip映射了一下。保存，source /etc/hosts

然后再次执行rabbitmqctl status就可以了。显示如下所示：
