Prior to gunicorn and nginx, i’ve tried to user apache + mod_wsgi and failed. Still don’t know why it fail. After 3 days trying, I give up. I have to look for another method, I try using gunicorn dan nginx, and It took me only 2 days for gunicord + nginx setup to works. 🙂
Here is condition on my Django + Gunicorn + Nginx setup:
- I use CentOS 7 on my server
- I create new user for running django (in my case /home/myuser)
- I install python 3.7.3, django, pandas, django_extensions, virtual environment, gunicorn dan nginx
- My django project folder is /home/myuser/myproject
- I put all my django app (created using ‘python manage.py startapp myapp apps/myapp’) in /home/myuser/myproject/apps

It’s my django project. Therefor, you might find my setup is not ideal, but it works! 🙂 (and it took me a week to make it works).
I learn that, most of tutorials use apt / apt-get for installation. Since I use CenOS (which use yum as default) I find it annoying. 😦
