RabbitMQ
安装成功后，cmd dos命令进入RabbitMQ的安装路径，如
E:Program FilesRabbitMQ Server abbitmq_server-3.6.10sbin>
输入以下命令查看mq状态
rabbitmqctl status
如果报错：
- Status of node 'rabbit@USER-20160821AY'
- Error: unable to connect to node 'rabbit@USER-20160821AY': nodedown
- DIAGNOSTICS
- ===========
- attempted to contact: ['rabbit@USER-20160821AY']
- rabbit@USER-20160821AY:
- * connected to epmd (port 4369) on USER-20160821AY
- * epmd reports node 'rabbit' running on port 25672
- * TCP connection succeeded but Erlang distribution failed
- * Authentication failed (rejected by the remote node), please check the Erlang cookie
- current node details:
- - node name: 'rabbitmq-cli-82@USER-20160821AY'
- - home dir: C:UsersAdministrator
- - cookie hash: /dNt52BJBOZo94nB/X3FKA==
根据提示，应该是Erlang的cookie出现问题，解决办法如下：
Erlang会生成两个cookie文件：C:Windows.erlang.cookie 及 C:用户你的用户名.erlang.cookie。检查两个文件内容是否一致，不一致用其中一个替换另一个即可。
