MongoDB/Startup

Starting

MongoDB can be started with systemd, or using the init.d startup scripts. I hate systemd so I went with the latter.

Start by creating the directory where MongoDB will keep all of its data. For example, I used /opt/mongodb. Set the permissions so that the mongodb user/group can read/write to this directory:

sudo chown -R mongodb:mongodb mongodb/

Now start the service, which is defined in /etc/init.d/mongodb:

sudo service mongodb start

You can issue the status command in place of the start command to check if the process is running:

$ sudo service mongodb status

You can also turn on logging, and look at the log files in /var/log/mongodb/mongodb.log [[Category:2018
