Rabbitmq启动报错

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

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

total 20

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

-rw-rw-r-- 1 rabbitmq rabbitmq    5 May 31 00:57 rabbit@firefly.pid

 

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

total 1212

drwxr-xr-x  3 rabbitmq rabbitmq    4096 May 30 22:25 ./

drwxr-xr-x 46 root     root        4096 May 21 05:45 ../

-rw-r-----  1 rabbitmq rabbitmq 1220937 May 31 01:52 erl_crash.dump

 

 

重启服务OK：

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

total 1212

drwxr-xr-x  3 rabbitmq rabbitmq    4096 May 30 22:25 ./
