How to use Django with uWSGI

uWSGI is a fast, self-healing and developer/sysadmin-friendly application container server coded in pure C.

The uWSGI docs offer a tutorial covering Django, nginx, and uWSGI (one possible deployment setup of many). The docs below are focused on how to integrate Django with uWSGI.

Prerequisite: uWSGI

The uWSGI wiki describes several installation procedures. Using pip, the Python package manager, you can install any uWSGI version with a single command. For example:

# Install current stable version.
$ pip install uwsgi

# Or install LTS (long term support).
$ pip install


Some distributions, including Debian and Ubuntu, ship an outdated version of uWSGI that does not conform to the WSGI specification. Versions prior to 1.2.6 do not call close on the response object after handling a request. In those cases the request_finished signal isn’t sent. This can result in idle connections to database and memcache servers.

uWSGI model

uWSGI operates on a client-server model. Your Web server (e.g., nginx, Apache) communicates with a django-uwsgi “worker” process to serve dynamic content. See uWSGI’s background documentation for more detail.

Configuring and starting the uWSGI server for Django

uWSGI supports multiple ways to configure the process. See uWSGI’s configuration documentation and examples.

Here’s an example command to start a uWSGI server:

uwsgi --chdir=/path/to/your/project \
    --module=mysite.wsgi:application \
    --env DJANGO_SETTINGS_MODULE=mysite.settings \
    --master --pidfile=/tmp/ \
    --socket= \      # can also be a file
    --processes=5 \                 # number of worker processes
    --uid=1000 --gid=2000 \         # if root, uwsgi can drop privileges
    --harakiri=20 \                 # respawn processes taking more than 20 seconds
    --max-requests=5000 \           # respawn processes after serving 5000 requests
    --vacuum \                      # clear environment on exit
    --home=/path/to/virtual/env \   # optional path to a virtualenv
    --daemonize=/var/log/uwsgi/yourproject.log      # background the process

This assumes you have a top-level project package named mysite, and within it a module mysite/ that contains a WSGI application object. This is the layout you’ll have if you ran django-admin startproject mysite (using your own project name in place of mysite) with a recent version of Django. If this file doesn’t exist, you’ll need to create it. See the How to deploy with WSGI documentation for the default contents you should put in this file and what else you can add to it.

The Django-specific options here are:

  • chdir: The path to the directory that needs to be on Python’s import path – i.e., the directory containing the mysite package.
  • module: The WSGI module to use – probably the mysite.wsgi module that startproject creates.
  • env: Should probably contain at least DJANGO_SETTINGS_MODULE.
  • home: Optional path to your project virtualenv.

Example ini configuration file:


Example ini configuration file usage:

uwsgi --ini uwsgi.ini

See the uWSGI docs on managing the uWSGI process for information on starting, stopping and reloading the uWSGI workers.
