Setup WSGI for Deployment

# Install a WSGI server
pip install gunicorn

# (Alternative)
pip install uwsgi
      

# project/wsgi.py

import os
from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.prod")
application = get_wsgi_application()
      

# Gunicorn (basic)
gunicorn project.wsgi:application

# Bind to network interface and set workers (general rule: 2-4 x CPU cores)
gunicorn --bind 0.0.0.0:8000 --workers 4 project.wsgi:application

# Daemonize to run in background (or prefer systemd below)
gunicorn --bind unix:/run/gunicorn.sock --workers 4 --daemon project.wsgi:application
      

# systemd service (Gunicorn) - /etc/systemd/system/gunicorn.service
