板卡掉电以后发现rabbitmq服务被停了，重启之：
[email protected]:/var/lib/rabbitmq/mnesia# cd /usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin/
[email protected]:/usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin# service rabbitmq-server start
* Starting message broker rabbitmq-server
* FAILED - check /var/log/rabbitmq/startup_\{log, _err\}
...fail!
发现失败！！！！！
查看报错log：
[email protected]:/usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin# cat /var/log/rabbitmq/startup_log
BOOT FAILED
===========
Error description:

{cannot_delete_plugins_expand_dir,
["/var/lib/rabbitmq/mnesia/[email protected]",
{cannot_delete,
"/var/lib/rabbitmq/mnesia/[email protected]",
eacces}]}}
Log files (may contain more information):
/var/log/rabbitmq/[email protected]
/var/log/rabbitmq/[email protected]
Stack trace:

提示无法删除文件夹/var/lib/rabbitmq/mnesia/[email protected]
上网查找类似错误，说是文件权限问题，发现报错文件夹属性为root:root
[email protected]:/usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin# cd /var/lib/rabbitmq/mnesia/
[email protected]:/var/lib/rabbitmq/mnesia# ll

drwxr-xr-x 2 root root 4096 May 31 01:44 [email protected]/
修改文件夹权限： chown -R rabbitmq:rabbitmq [email protected]/
重启仍然报错！！！！
发现mnesia的属性也是root：
[email protected]:/var/lib/rabbitmq# ll
total 1212
drwxr-xr-x 3 rabbitmq rabbitmq 4096 May 30 22:25 ./
drwxr-xr-x 46 root root 4096 May 21 05:45 ../

drwxr-xr-x 4 root root 4096 May 31 01:44 mnesia/
修改之： chown -R rabbitmq:rabbitmq mnesia/[email protected]:/var/lib/rabbitmq# chown -R rabbitmq:rabbitmq mnesia/
重启服务OK：
