Django is a powerful framework for building websites. To run a production website, usually an application server is used. So nginx will do two basic things:

• Serve your Django application from the application server port to the web port (Reverse Proxy)
• Serve static and media files

The application server used in this example is gunicorn, the application server chosen by Instagram of the earlier days, but it can be anything running on port 9999. Change port number as required in the example.

The following nginx conf was adapted from this, with some additions and it contains:

• a commented non www to www website redirect
• gzip for javascript, json, css and proxy routes
• media files with etag (1 year)
• static files with etag (1 minute)
• an host-based favicon distributor (reusable as is)
• a commented basic auth to make a website private
• reverse proxy to gunicorn
• a simple block for a common type of malicious activity

It works fine with Django 1 and 2.

# uncomment for redirect
# server {
#    # redirect WITH www from example.com and example.net
#    listen 80;
#    server_name example.com example.net;
#    return 301 http://www.example.com$request_uri;
# }

    listen	80;
    # the domain name it will serve for
    server_name www.example.com;

Run nginx -t to check and then systemctl reload nginx to apply.

This is a http version, to configure the website for https follow this howto.
