RabbitMQ error : cannot_delete_plugins_expand_dir

通过命令

rabbitmq-server

前台启动RabbitMQ报错

...

查看对应目录

ll /var/lib/rabbitmq/mnesia

drwxr-xr-x. 5 rabbitmq rabbitmq 4096 11月 30 16:21 rabbit@centos7
- rw-r- -r- -. 1 rabbitmq rabbitmq 148   7月  25 23:25 rabbit@centos7-feature_flags
drwxr-xr-x. 3 root         root         4096  8月   6 12:07 rabbit@centos7-plugins-expand

修改对应目录所有者和所在组

chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/mnesia/rabbit@centos7-plugins-expand/

drwxr-xr-x. 5 rabbitmq rabbitmq 4096 11月 30 16:27 rabbit@centos7
- rw-r- -r- -. 1 rabbitmq rabbitmq  148 7月  25 23:25 rabbit@centos7-feature_flags
drwxr-xr-x. 3 rabbitmq rabbitmq 4096 8月   6 12:07 rabbit@centos7-plugins-expand

再次启动，不再报错。

附：后台方式启动RabbitMQ命令

rabbitmq-server -detached
