问题1
使用命令启动
service rabbitmq-server start
报错如下：
Starting rabbitmq-server (via systemctl): Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details. [FAILED]
解决办法：
尝试下面的操作：
禁用 SELinux ，修改 /etc/selinux/config
SELINUX=disabled
修改后重启系统
问题2：
一般使用命令
rabbitmq-server start
可以查看启动相关日志的

解决办法：
find / -name recovery.dets
然后使用 rm 命令删除掉 recoer.dets 文件
问题3：
使用命令
rabbitmq-server start
报错如下： 提示 no space left on device
/usr/lib/rabbitmq/bin/rabbitmq-server: line 51: echo: write error: No space left on device Failed to write pid file: /var/lib/rabbitmq/mnesia/rabbit@n3.pid
解决办法：
查看磁盘占用情况
df -h
然后使用
cd / #回到根目录 du -sh * # 查看各个文件夹占用磁盘情况
然后看哪个盘数据多， 就cd 进入哪个盘，然后进行最终找到数据量大的文件。一般是日志文件的话，删除即可。
