【问题描述】：
刚刚在 CentOS 7.6 上安装了 MongoDB，但无法启动，错误代码为 14：
[mehrdad@MHRS ~]$ sudo service mongod status

参见“Failed to unlink socket file /tmp/mongodb-27017.sock Permission denied”。
但我检查了/tmp/mongodb-27017.sock 权限：
[mehrdad@MHRS ~]$ sudo ls -l /tmp/mongodb-27017.sock
[sudo] password for mehrdad:
srwx------. 1 mongod mongod 0 Feb 7 16:15 /tmp/mongodb-27017.sock
如您所见，所有权是正确的。
有什么问题？
