Django is a web development framework for the Python programing
language. It enables rapid development, while favoring pragmatic and
clean design. Django was initially developed for use in a newspaper's
website division, and as a result the Django framework is very well
suited to developing content-centric applications.
This guide provides an introduction to getting started with the Django
framework, using the ``mod_wsgi`` method of deploying python
applications. Please complete the the `getting started guide
</getting-started/>`_
prior to beginning this guide on an up to date system. Furthermore,
you will want a running `Apache web server
</web-servers/apache/installation/debian-6-squeeze>`_
and a functional `MySQL database </databases/mysql/debian-6-squeeze>`_
.. contents:: Contents
Set the Hostname
----------------
Before you begin installing and configuring the components described
in this guide, please make
sure you've followed our instructions for `setting your hostname
</getting-started#sph_set-the-hostname>`_.
Issue the following commands to make sure it is set properly: ::
hostname
hostname -f
The first command should show your short hostname, and the second
should show your
fully qualified domain name (FQDN).
Install Dependencies
--------------------
Issue the following commands to ensure that your system's package
repositories and installed programs are up to date and all required
software is installed::
apt-get update
apt-get upgrade
apt-get install python-setuptools libapache2-mod-wsgi
Additionally you will need to install a database system and a python
driver for this database system. If you want to run the `MySQL
database engine </databases/mysql/debian-6-squeeze>`_ issue the
following command: ::
apt-get install mysql-server python-mysqldb
If you want to run the `PostgreSQL database server
</databases/postgresql/debian-6-squeeze>`_
issue the following command::
apt-get install postgresql python-psycopg2
If you want to use the SQLite embedded database, issue the following
command::
apt-get install sqlite3 python-sqlite
Your application may require additional dependencies. You may install
these either using the Debian package tools or by using the
``easy_install`` command included in ``python-setuptools``.
Install Django
--------------
There are two methods for installing Django. You may either choose to
install the Django packages from the Debian repositories, or you can
install using the python ``easy_install`` method. The version of
Django in the package repositories is more stable and benefits from
testing and maintenance by Debian developers; however, using
``easy_install`` will always provide access to the latest features.
To install Django from the Debian repositories issue the following
command::
apt-get install python-django
If you want to install Django using the ``easy_install`` tool, issue
the following command: ::
easy_install Django
At the time of writing, this will install version 1.2.5 of the Django
framework. Consider the `package information for Django
<http://pypi.python.org/pypi/Django>`_
for more information.
Configure Django Applications for WSGI
--------------------------------------
In order for ``mod_wsgi`` to be able to provide access to your Django
application, you will need to create a ``django.wsgi`` file inside of
your application directory. For the purposes of this example, we
assume that your application will be located *outside* of your
``DocumentRoot`` in the directory ``/srv/www/ducklington.org/application``.
Modify this example and all following examples to conform to the actual files
and locations used in your deployment.
.. file:: /srv/www/ducklington.org/application/django.wsgi
:lang: python
import os
import sys
sys.path.append('/srv/www/ducklington.org/application')
os.environ['PYTHON_EGG_CACHE'] = '/srv/www/ducklington.org/.python-egg'
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
You must append the path of your application to the system path as
above. Additionally, declaration of the ``PYTHON_EGG_CACHE`` variable
is optional but may be required for some applications when WSGI
scripts are executed with the permissions of the web server. Finally,
the ``DJANGO_SETTINGS_MODULE`` must refer to the Django
``settings.py`` file for your project. You will need to restart Apache
after modifying the ``django.wsgi`` file.
Configure Apache
----------------
Consider the following example virtual host configuration:
.. excerpt:: Apache Virtual Host Configuration
:lang: apache
<VirtualHost *:80>
ServerName ducklington.org
ServerAlias www.ducklington.org
ServerAdmin squire en ducklington.org
DocumentRoot /srv/www/ducklington.org/public_html
WSGIScriptAlias / /srv/www/ducklington.org/application/django.wsgi
<Directory /srv/www/ducklington.org/application>
Order allow,deny
Allow from all
</Directory>
Alias /robots.txt /srv/www/ducklington.org/public_html/robots.txt
Alias /favicon.ico /srv/www/ducklington.org/public_html/favicon.ico
Alias /images /srv/www/ducklington.org/public_html/images
Alias /static /srv/www/ducklington.org/public_html/static
ErrorLog /srv/www/ducklington.org/logs/error.log
CustomLog /srv/www/ducklington.org/logs/access.log combined
</VirtualHost>
In this example, the ``WSGIScriptAlias`` directive tells Apache that
for this virtual host, all requests below ``/`` should be handled
by the WSGI script specified. In the directory block that follows, we
allow Apache to serve these requests. Finally, the series of four
``Alias`` directives allow Apache to serve the ``robots.txt`` and
``favicon.ico`` files as well as all resources beneath the
``/images`` and ``/static`` locations, directly from the
``DocumentRoot`` without engaging the WSGI application. You can add as
many Alias directives as you need to.
When you have successfully configured your Apache virtual host, issue
the following commands to disable the default virtual host and restart
the web server::
a2dissite default
/etc/init.d/apache2 restart
You will need to restart the web server every time the ``django.wsgi``
file changes. However, all other modifications to your application do
not require a web server restart. Congratulations! You have now
successfully deployed a Django application using ``mod_wsgi``.
