Job for mongod.service failed ——一次因为Linux权限问题导致的MongoDB启动失败

前言

最新因为安全性问题修改了MongoDB的配置文件,结果在重启MongoDB服务时却爆出了这个错误:

Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.

不明觉厉,那就先照着指引一步一步来,首先复制指令:systemctl status mongod.service

运行之后果然发现了一个错误:

● mongod.service - MongoDB Database ServerLoaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)Active: active (running) since Fri 2021-04-23 09:45:33 CST; 13min agoDocs: https://docs.mongodb.org/manualProcess: 8633 ExecStart=/usr/bin/mongod $OPTIONS (code=exited, status=14)Process: 8631 ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb (code=exited, status=0/SUCCESS)Process: 8629 ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb (code=exited, status=0/SUCCESS)Process: 8628 ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb (code=exited, status=0/SUCCESS)Main PID: 8636 (mongod)CGroup: /system.slice/mongod.service└─8636 /usr/bin/mongod -f /etc/mongod.confApr 23 09:45:31 VM-4-13-centos systemd[1]: Starting MongoDB Database Server...

Process: 8633 ExecStart=/usr/bin/mongod $OPTIONS (code=exited, status=14)

这里报了个错误,导致MongoDB服务无法启动,谷歌一下发现应该是属于Linux系统的权限问题。

解决方案

以CentOS系统为例,我们进入到/tmp目录并找到mongodb-27017.sock文件

[root@centos ~]# cd /tmp
[root@centos ~]# ls -l *.sock

修改文件权限:

chown mongod:mongod mongodb-27017.sock

重启MongoDB,发现没有问题,已经成功启动:

通过http方式访问:

至此,问题解决
