MongoDB.service failed with result exit-code

Question

I can't start mongoDB with the command "sudo systemctl start mongod".

I'm getting the following message :

● mongod.service - MongoDB Database Server
   Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Wed 2020-02-19 22:39:00 CET; 2s ago

I've already reinstalled mongodb and I having the same problem. I don't know where the error came from if you can help me. Thank you.

Answer 1

Just do those two commands for temporary solution:

sudo rm -rf /tmp/mongodb-27017.sock
sudo service mongod start

For details:

That shall be fault due to user permissions in .sock file, You may have to change the owner to monogdb user.

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

Answer 2

I had the same problem in Manjaro and these commands solved it:

chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock

Answer 3

This worked for me and I don't reinstall MongoDB. I have created manually

sudo mkdir /var/lib/mongodb
sudo mkdir /var/log/mongodb

and changed owner for both

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb
