Mongod.service wont start after reinstall

Ole_J · 2022-05-25T17:39:41.975Z

I uninstalled and removed the data lib and the config file, and then reinstalled with apt-get.
What I don’t understand is, that the installation didn’t make a new config file and the service suddenly didn’t work. I would expect a clean installation, that works ?

Ole_J:

ERROR: child process failed, exited with 100

That is not the same error as before. The most likely reason for this is that you did not terminated the mongod you started manually.

Ole_J · 2022-05-25T18:18:39.672Z

I did terminate that process. And I have seen that error before.
I would like to find out why that child process gave an error.

Share the output of

ls -ld /var/lib/mongodb

oaj@pop-os:/$ ls -ld /var/lib/mongodb

Okay that looks good.

Share your mongodb service file.

Because of

Ole_J:

Group=mongodb

in service file, try to chgrp mongodb /var/lib/mongodb/

It is nogroup now.

Output of

ls -ld /var/lib/mongodb/

Please show the output of

ss -tlnp
ps -aef | grep [m]ongod
ls -l /var/run/mongodb/mongod.pid
ls -l /tmp/mongodb-*
