问题描述：

安装完 `ErLang` 和 `RabbitMQ` 之后执行 `rabbitmqctl status` 报错：

Error: unable to perform an operation on node 'rabbit@wangshuo'. 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@wangshuo
     * If target node is configured to use long node names, don't forget to use --longnames with CLI tools
    
    DIAGNOSTICS
    ===========
    
    attempted to contact: [rabbit@wangshuo]
    
    rabbit@wangshuo:
      * connected to epmd (port 4369) on wangshuo
      * epmd reports: node 'rabbit' not running at all
                      no other nodes on wangshuo
      * suggestion: start the node
    
    Current node details:
     * node name: 'rabbitmqcli-19760-rabbit@wangshuo'
     * effective user's home directory: C:\Users\13343
     * Erlang cookie hash: y1wQRjvcOXX+x5pqGKKOWw==

错误的原因是 Erlang 的 cookie 出现问题，Erlang 会生成两个 cookie 文件：`C:\Windows\System32\config\systemprofile\.erlang.cookie` 及 `C:\用户\你的用户名\.erlang.cookie`。

用后者的文件替换掉前者的文件。

如果还不行，那就卸载了，然后使用 **默认路径** 重装。

我重装之后执行 `rabbitmqctl status` 好了：

然后执行 `rabbitmq-plugins enable rabbitmq_management`：

这个时候在浏览器访问 `http://localhost:15672/` 即可看到页面。
