Mongodb not working on Ubuntu 16.04

Question

I installed mongodb following this tutorial here, no errors during the installation but when I try to start the mongod server using this command sudo systemctl start m

Answer 1

because the permission setting

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

if this worked for me after reinstalling 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
chown -R mongodb:mongodb /var/log/mongodb

Answer 2

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.

I solved the problem by the command:

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

sudo systemctl restart mongod

Then check your mongodb service

sudo systemctl status mongod

Answer 3

The problem may be related to the lack of space with your /dev/root/ (it was mine).

Check with df -h and see if there enough free space. Otherwise, as explain there, try to free some space by moving the log files to another disk.

sudo /etc/init.d/rsyslog stop
sudo mv /var/log /OTHERDISK/
sudo ln -s /OTHERDISK/log /var/log
sudo /etc/init.d/rsyslog start

Hope it could help as it helps me

Answer 5

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

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

Answer 6

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.

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 mongodb user.

sudo chown mongodb /tmp/mongodb-27017.sock
sudo chgrp mongodb /tmp/mongodb-27017.sock

After this sudo systemctl status mongodb working fine and mongodb is started.
