开发老哥优化了消息队列，发布至服务器端时发现rabbitmq管理界面进不去了
遂重启rabbitmq：
rabbitmqctl stop ：停止rabbitmq
rabbitmq-server restart : 重启rabbitmq
然后就报错了。。。

说是无法删除/var/lib/rabbitmq/mnesia/rabbit@****-plugins-expand和/rabbit_webmachine.beam
那好吧我手动删掉
删掉之后继续重启
果然又报错了

5672端口占用，奇怪我不是停止服务了吗？

被docker占用？询问同事得知之前的rabbitmq是在docker内运行的，但是服务器上也安装了，于是直接kill掉docker
然后以服务方式启动rabbitmq

启动成功，偶然发现以服务方式启动不会卡界面，使用rabbitmq-server启动的时候会停留在前台

想ctrl+c继续输命令又害怕停掉服务，只能克隆一个会话继续操作，以服务方式启动确实方便很多
又发现新发布的war包没有被tomcat自动解析。。。
重启tomcat
完成
进rabbitmq的管理界面15672，发现以前的用户名+密码登不进去，估计是因为以前用的docker里的rabbitmq，重新创建用户，给权限
rabbitmqctl add_user admin admin
rabbitmqctl set_permissions admin ".*" ".*" ".*"
好了
网上现有的解决方案都是 /var/lib/rabbitmq/mnesia/rabbitmq@localhost/recovery.dets文件的锅，删除该文件重新启动即可，一开始百度没找到解决方案，遂查看日志，找到原因。记录一下
