I found a great Bitnami Docs KB article describing how to check the status of, and stop/start/restart the services running on your Bitnami instance.

Each Bitnami stack includes a control script that lets you easily check the status of, stop, start and restart services.

These are the commands that you would use. If you use them as-is below it will perform the specified action against all the Bitnami services on your instance.

sudo /opt/bitnami/ctlscript.sh status
sudo /opt/bitnami/ctlscript.sh start
sudo /opt/bitnami/ctlscript.sh stop
sudo /opt/bitnami/ctlscript.sh restart

Or use any of the above against a single service that is running, such as Apache only, by passing the service’s name as an argument after the desired action, such as restart.

sudo /opt/bitnami/ctlscript.sh restart apache

The easiest way to learn the names of the services that are on your Bitnami instance is by simply checking all of their statuses with the status command as it returns the names of all the services on your instance.

sudo /opt/bitnami/ctlscript.sh status
