Django will work +with any version of Apache which supports mod_wsgi. + +.. _python wsgi interface: http://www.python.org/dev/peps/pep-0333/ + +The `official mod_wsgi documentation`_ is fantastic; it's your source for all +the details about how to use mod_wsgi.

This tells Apache +to serve any request below the given URL using the WSGI application defined by that file. + +Next we'll need to actually create this WSGI application, so create the file +mentioned in the second part of ``WSGIScriptAlias`` and add:: + + import os + import sys + + os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings' + + import django.core.handlers.wsgi + application = django.core.handlers.wsgi.WSGIHandler() + +If your project is not on your ``PYTHONPATH`` by default you can add:: + + path = '/usr/local/django' + if path not in sys.path: + sys.path.append(path) + +just above the final ``import`` line to place your project on the path. Remember to +replace 'mysite.settings' with your correct settings file, and '/usr/local/django' +with your own project's location. + +Serving media files +=================== + +Django doesn't serve media files itself; it leaves that job to whichever Web +server you choose. + +We recommend using a separate Web server -- i.e., one that's not also running +Django -- for serving media. Here are some good choices: + + * lighttpd_ + * Nginx_ + * TUX_ + * A stripped-down version of Apache_ + * Cherokee_ + +If, however, you have no option but to serve media files on the same Apache +``VirtualHost`` as Django, you can set up Apache to serve some URLs as +static media, and others using the mod_wsgi interface to Django. + +This example sets up Django at the site root, but explicitly serves ``robots.txt``, +``favicon.ico``, any CSS file, and anything in the ``/media/`` URL space as a static +file. All other URLs will be served using mod_wsgi:: + + Alias /robots.txt /usr/local/wsgi/static/robots.txt + Alias /favicon.ico /usr/local/wsgi/static/favicon.ico + + AliasMatch /([^/]*\.css) /usr/local/wsgi/static/styles/$1 + + Alias /media/ /usr/local/wsgi/static/media/ + + <Directory /usr/local/wsgi/static> + Order deny,allow + Allow from all + </Directory> + + WSGIScriptAlias / /usr/local/wsgi/scripts/django.wsgi + + <Directory /usr/local/wsgi/scripts> + Order allow,deny + Allow from all + </Directory> + +.. _lighttpd: http://www.lighttpd.net/ +.. _Nginx: http://wiki.nginx.org/Main +.. _TUX: http://en.wikipedia.org/wiki/TUX_web_server +.. _Apache: http://httpd.apache.org/ +.. _Cherokee: http://www.cherokee-project.com/ + +More details on configuring a mod_wsgi site to serve static files can be found +in the mod_wsgi documentation on `hosting static files`_. + +.. _hosting static files: http://code.google.com/p/modwsgi/wiki/ConfigurationGuidelines#Hosting_Of_Static_Files + +Details +======= + +For more details, see the `mod_wsgi documentation on Django integration`_, +which explains the above in more detail, and walks through all the various +options you've got when deploying under mod_wsgi. + +.. _mod_wsgi documentation on Django integration: http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango |
