Recently i have solved the same issue. I was unable to find the solution on googled, but i get come clues to, how get figure it out. In my case this issue was related to mongodb-27017.sock file.
最近我解决了同样的问题。我无法在谷歌上找到解决方案，但我得到了一些线索，如何弄清楚。就我而言，此问题与 mongodb-27017.sock 文件有关。
Failed to unlink socket file /tmp/mongodb-27017.sock errno:1 Operation not permitted
So i have changed the permission of /tmp/mongodb-27017.sock file to default mongodbuser.
所以我已将 /tmp/mongodb-27017.sock 文件的权限更改为默认mongodb用户。
sudo chown mongodb /tmp/mongodb-27017.sock
sudo chgrp mongodb /tmp/mongodb-27017.sock
After this sudo systemctl status mongodbworking fine and mongodbis started.
在此sudo systemctl status mongodb工作正常并mongodb启动之后。

Stumbed on the same issue, just reboot
遇到同样的问题，重启
sudo reboot
回答by Dara Vichit
This error returned by MongoDB applications which encounter an unrecoverable error, an uncaught exception or uncaught signal. The system exits without performing a clean shutdown.
此错误由遇到不可恢复错误、未捕获异常或未捕获信号的 MongoDB 应用程序返回。系统退出而不执行干净关闭。
I solved the problem by the command:
我通过命令解决了这个问题：
sudo chown -R mongodb:mongodb /var/log/mongodb
sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chmod -R 755 /var/lib/mongodb
sudo chmod -R 755 /var/log/mongodb
sudo chown mongodb /tmp/mongodb-27017.sock
sudo chgrp mongodb /tmp/mongodb-27017.sock
Then restart service
然后重启服务
sudo systemctl restart mongod
Then check your mongodb service
然后检查你的mongodb服务
sudo systemctl status mongod

The first thing, you should examine the mongo log. It should tell you what went wrong.
首先，您应该检查 mongo 日志。它应该告诉你出了什么问题。
$ tail -n 100 /var/log/mongodb/mongod.log
$ tail -n 100 /var/log/mongodb/mongod.log
This command will show last 100 lines of the log file which will point you to the exact problem.
此命令将显示日志文件的最后 100 行，它将指向您确切的问题。
For example, mine wasn't working because i was running a mongoinstance using the same port 27017. when i ran another instance, the instance failed to load.
例如，我的无法工作，因为我正在mongo使用相同的端口运行一个实例27017。当我运行另一个实例时，该实例无法加载。

I was getting the similar error, in my case mongo couldn't use 27017. I needed to stop whatever was using 27017 port and restart mongo.
我遇到了类似的错误，在我的情况下 mongo 无法使用 27017。我需要停止使用 27017 端口的任何内容并重新启动 mongo。

The problem may be related to the lack of space with your /dev/root/(it was mine).
问题可能与您的/dev/root/（是我的）空间不足有关。
Check with df -hand see if there enough free space.
Otherwise, as explain there, try to free some space by moving the log files to another disk.
检查df -h并查看是否有足够的可用空间。否则，按照那里的解释，尝试通过将日志文件移动到另一个磁盘来释放一些空间。
sudo /etc/init.d/rsyslog stop
sudo mv /var/log /OTHERDISK/
sudo ln -s /OTHERDISK/log /var/log
sudo /etc/init.d/rsyslog start

After googling around for a while. I found that that is because the permission setting on /var/lib/mongodb and /tmp/mongodb-27017.lock are wrong. You will have to change the owner to monogdb user
在谷歌搜索了一段时间后。我发现这是因为 /var/lib/mongodb 和 /tmp/mongodb-27017.lock 上的权限设置错误。您必须将所有者更改为 monogdb 用户
chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock
