今天服务器登录不了，到腾讯云管理平台强制重启后，rabbitmq启动不了了

报错如下：

[root@VM_0_2_centos ~]# rabbitmq-plugins enable rabbitmq_management

Plugin configuration unchanged.

原因可能是磁盘满了（检查发现并没有满），或者是强制重启后，恢复队列数据损坏导致的，找到相关目录删除后重启即可：

根据服务器环境不同，以下路径可能不同，删除以下路径中queues下的文件

/var/lib/rabbitmq/mnesia/rabbit@VM_0_2_centos/msg_stores/vhosts/628WB79CIFDYO9LJI6DKMI09L/queues

然后重启：

service rabbitmq-server start
