RabbitMQ启动失败解决

使用systemctl start rabbitmq-server.service启动rabbitmq时报错：

[root@rhos5-rabbitmq1 ~]# systemctl start rabbitmq-server
Jun 13 21:03:08 jeckersb-f20 systemd[1]: Starting RabbitMQ broker...

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

nodes in question: ['rabbit@rhos5-rabbitmq1']

hosts, their running nodes and ports:
- rhos5-rabbitmq1: [{rabbitmqctl2980,45861}]

current node details:
- node name: 'rabbitmqctl2980@rhos5-rabbitmq1'
- home dir: /var/lib/rabbitmq
- cookie hash: vzI5NUyusQhCrkRr6GAhpQ==

这个根本看不出启动失败原因
看了一些原因，有的说是文件需要删除
/var/lib/rabbitmq/mnesia 目录下存在[email protected]、rabbit@localhost、rabbit@localhost-plugins-expand，删除这3项后，再使用systemctl start rabbitmq-server启动，发现还是启动失败
又换了直接使用rabbitmq-server启动
这次提示：

{"could not start kernel pid",application_controller,"error in config file \"c:/Users/yupeipei/AppData/Roaming/RabbitMQ/
rabbitmq.config\" (256): syntax error before: ']'"}
could not start kernel pid (application_controller) (error in config file "c:/Users/yupeipei/AppData/Roaming/RabbitMQ/ra
bbitmq.config" (256): syntax error before: ']')

发现自己编辑 /etc/rabbitmq/rabbitmq.config 文件。添加远程访问用户的配置多了一个逗号 ‘,’

[
{rabbit, [{tcp_listeners, [5672]}, {loopback_users, [“asdf”]},]}
]

删除逗号在次重启，服务成功启动！
