i am on centos 7 when i trying to run sudo service mongod start i got an error like this
Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.
The first thing to do when you get an error message that says
is to see “systemctl status mongod.service” and “journalctl -xe” for details.
Even us, we cannot help you without the details.

Hi,
you can see what are the errors, by typing in the shell:
systemctl status mongod.service
journactl -xe
tail -f /path/to/log_file/mongod.log
Regards
I had the same error as OP and this is the output of journactl -xe:

The first thing to do is to look at the log.
I could see that the logs folder from /var/log was deleted and this caused the db to shut down.
The below steps resolved the issue -
- switch to root user “sudo su”
- cd /var/log/
- mkdir mongodb
- chown -R mongod:mongod mongodb
- systemctl start mongod.service

Hi Steeve,
I’m again facing issues with MongoDB. This time its a different error. I think its the space issue.
Check free space on your /var/log mount point
df -k /var/log
df -i /var/log
Clean unnecessary files

For me its was the permission conflict on the sock file /tmp/mongodb-27017.sock
/tmp/mongodb-27017.sock was owned by root:root while mongod was not which cause permission denied error.
a quick fix was to
rm -rf /tmp/mongodb-27017.sock
and the rum
systemctl restart mongod
