Supervisor is meant to restart if the server goes down. Since we are not having it in this tutorial about django, gunicorn and postgres, does it mean this system does its job?

Thank you! very much! I followed the most recent tutorial and it used systemd, it is working well, my question was just to find an answer to the question that I asked myself. Appreciate your time and knowledge sharing. So far, very happy with digitalocean, their tutorials make it a very effective avenue to sign up because it is an essential guide for those of us starting from scratch.

Heya, @977ef09003a542a28c2984affdd220

Most modern Linux systems (like Ubuntu 20.04+) use systemd as the default service manager. It’s often preferred over Supervisor because it’s native to the system and lightweight.

To check if systemd is managing Gunicorn in your setup:

Look for a service file (usually in /etc/systemd/system/gunicorn.service):

sudo systemctl status gunicorn

If it exists, the tutorial likely uses systemd to manage Gunicorn instead of Supervisor.

Hey,

As KFSys mentioned, Supervisor (or alternatives like systemd) is essential for managing processes like Gunicorn in a production environment. It makes sures that your app automatically restarts if it crashes or the server reboots.

In addition to that, if you’re deploying your app on a platform like DigitalOcean App Platform or using Docker containers, these platforms or tools often have built-in mechanisms to manage and restart services, making Supervisor or systemd unnecessary in such setups.

For traditional VPS setups, though, adding Supervisor or configuring systemd is a best practice to keep your app running smoothly.
