To change the location used by MongoDB to store its data, you need to:
/etc/mongodb.conf and change the line
dbpath=/var/lib/mongodb to the path that you desire, e.g.
- Update the permissions of your chosen path to allow the
mongodb user to write to it, e.g.
chown -R /home/user/data/mongodb
- Restart the MongoDB service by running
sudo restart mongodb
Note that if you have any data in the old location that you want to keep, you'll need to stop the MongoDB service first, manually move the files and then start the service again.
To stop the MongoDB server use
sudo service mongodb stop
