The first thing to do when you get an error message that says

Brijesh_Kalkani:

See "systemctl status mongod.service" and "journalctl -xe" for details.

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

I had the same error as OP and this is the output of journactl -xe:

Hey there!
This is what i got. Could you help me out here?

steevej · 2022-07-06T16:12:42.256Z

The first thing to do is to look at the log.

Mirna_Daniel · 2022-07-08T12:30:53.850Z

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

Mirna_Daniel · 2022-07-08T14:15:27.096Z

Hi Steeve,

I’m again facing issues with MongoDB. This time its a different error. I think its the space issue.

Ramachandra_Tummala · 2022-07-09T02:02:20.159Z

Check free space on your /var/log mount point
df -k /var/log
df -i /var/log
Clean unnecessary files

Christian_Augustine · 2023-09-01T09:08:40.672Z

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
