What is the usage of supervisor in Ubuntu?

In Ubuntu, Supervisor is a process control system designed to monitor and manage processes. It helps users automatically start applications during system boot, monitor their running status, and restart them if necessary.

To use Supervisor in Ubuntu, you first need to install the Supervisor package. You can install it using the following command:

sudo apt-get update
sudo apt-get install supervisor

After installation is complete, you can use the following commands to start, stop, and restart the Supervisor service:

sudo service supervisor start
sudo service supervisor stop
sudo service supervisor restart

Set the working directory of Supervisor to /etc/supervisor/conf.d/ and create a configuration file in that directory to specify the processes to be monitored. For example, you can create a file named myapp.conf.


Reload Supervisor to apply the new configuration.

sudo supervisorctl reread
sudo supervisorctl update

Finally, you can use the supervisorctl command to view and manage processes in Supervisor. For example, to check the status of all processes, you can run:

sudo supervisorctl status

You can manage and monitor processes in Ubuntu using Supervisor by following these steps.
