关于Linux系统下无法正常运行rabbitMq的问题
安装完rabbitMq后，执行rabbit-server，成功，但进行其他操作会报错，在外部web访问时，无法登陆等情况，主要错误如下：
[root@node04 sbin]# rabbitmqctl status
Status of node rabbit@node04 ...
Error: unable to connect to node rabbit@node04: nodedown
DIAGNOSTICS
===========
attempted to contact: [rabbit@node04]
rabbit@node04:
* connected to epmd (port 4369) on node04
* epmd reports node 'rabbit' running on port 25672
* TCP connection succeeded but Erlang distribution failed
* suggestion: hostname mismatch?
* suggestion: is the cookie set correctly?
* suggestion: is the Erlang distribution using TLS?
current node details:
- node name: 'rabbitmq-cli-33@node04'
- home dir: /var/lib/rabbitmq
- cookie hash: SvKh9AJRNCo5gQiiaugMfg==
解决方式：启动rabbitMq时，使用如下命令启动，即可解决启动运行不成功的情况
rabbitmq-server -detached
