Rabbitmq启动报错

板卡掉电以后发现rabbitmq服务被停了，重启之：

root@firefly:/var/lib/rabbitmq/mnesia# cd /usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin/

root@firefly:/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：

root@firefly:/usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin# cat /var/log/rabbitmq/startup_log

提示无法删除文件夹/var/lib/rabbitmq/mnesia/rabbit@firefly-plugins-expand

 

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

root@firefly:/usr/lib/rabbitmq/lib/rabbitmq_server-3.2.4/sbin# cd /var/lib/rabbitmq/mnesia/

root@firefly:/var/lib/rabbitmq/mnesia# ll

修改文件夹权限： chown -R rabbitmq:rabbitmq rabbit@firefly-plugins-expand/

 

重启仍然报错！！！！

发现mnesia的属性也是root：

root@firefly:/var/lib/rabbitmq# ll

drwxr-xr-x  4 root     root        4096 May 31 01:44 mnesia/

 

修改之： chown -R rabbitmq:rabbitmq mnesia/root@firefly:/var/lib/rabbitmq# chown -R rabbitmq:rabbitmq mnesia/

 

重启服务OK：
