mongodb - MongoDB 4 无法在 CentOS 7.6 中启动，错误代码为 14

问题描述

刚刚在 CentOS 7.6 上安装了 MongoDB，但无法以错误代码 14 开始：

   [mehrdad@MHRS ~]$ sudo service mongod status
    Redirecting to /bin/systemctl status mongod.service
    ● mongod.service - MongoDB Database Server

这是 MongoDB 日志：

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。

问题是什么？
