Changed tutorial2 to use 'django-admin runserver' instead of mod_python. Also updated WSGI mentions in the docs, now that we're WSGI-friendly.

Install Apache and mod_python
|
||||
=============================
|
||||
|
||||
Currently, Django runs on Apache_ with `mod_python`_. mod_python is similar to
|
||||
mod_perl -- it embeds Python within Apache and loads Python code into memory
|
||||
when the server starts. Code stays in memory throughout the life of an Apache
|
||||
process, which leads to significant performance gains over CGI.

If you just want to experiment with Django, skip this step. Django comes with

||||
its own Web server for development purposes.

The admin isn't necessarily intended to be used by site visitors; it's for site

managers.
|
||||
|
||||
Expose the admin media files
|
||||
Start the development server
|
||||
============================
|
||||
|
||||
Django's admin is intended to be fully functional and good looking. For that
|
||||
reason, Django ships with admin media files -- CSS, JavaScript and images --
|
||||
that comprise the admin's design. To set up a Django admin instance, the first
|
||||
thing to do is put those media files online somewhere.
|
||||
To make things easy, Django comes with a pure-Python Web server that builds on
|
||||
the BaseHTTPServer included in Python's standard library. Let's start the
|
||||
server and explore the admin site. First, set the ``DJANGO_SETTINGS_MODULE``
|
||||
environment variable to the location of your admin settings::
|
||||
|
||||
(Note: Although Django ships with a default design for its admin site, you can
|
||||
change it however you'd like. The admin uses Django's own template system and
|
||||
is powered -- surprise, surprise -- by Django itself, so it is completely
|
||||
customizable.)
|
||||
export DJANGO_SETTINGS_MODULE=myproject.settings.admin
|
||||
|
||||
The files are in the ``media`` directory of the Django distribution. To
|
||||
"activate" them, copy that directory under a Web document root somewhere, so
|
||||
that you can access them via the Web.
|
||||
Then, run this command to start the server::
|
||||
|
||||
Be careful not to put your Python source code under the Web document root. Just
|
||||
do the media files.
|
||||
django-admin.py runserver
|
||||
|
||||
Then, tell Django where you put them, via ``ADMIN_MEDIA_PREFIX`` in the
|
||||
``myproject.settings.admin`` settings file. Examples::
|
||||
It'll start a Web server running locally -- on port 8000, by default. If you
|
||||
want to change the server's port, pass it as a command-line argument::
|
||||
|
||||
# You can leave off the domain if they're on the same domain as your admin
|
||||
# site will be.
|
||||
ADMIN_MEDIA_PREFIX = '/adminmedia/'
|
||||
django-admin.py runserver 8080
|
||||
|
||||
# Otherwise, use the fully-qualified domain.
|
||||
ADMIN_MEDIA_PREFIX = 'http://www.foo.com/adminmedia/'
|
||||
|
||||
Make sure to include a trailing slash.
|
||||
|
||||
Hook into mod_python
|
||||
====================
|
||||
|
||||
Now let's take the opportunity to hook Django into Apache/mod_python. Edit your
|
||||
``httpd.conf`` file and add this::
|
||||
|
||||
<Location "/admin/">
|
||||
SetHandler python-program
|
||||
PythonHandler django.core.handlers.modpython
|
||||
SetEnv DJANGO_SETTINGS_MODULE myproject.settings.admin
|
||||
PythonDebug On
|
||||
</Location>
|
||||
|
||||
This tells Apache: "Use mod_python for any URL at or under '/admin/', using the
|
||||
Django mod_python handler." It also passes the value of ``DJANGO_SETTINGS_MODULE``,
|
||||
so mod_python knows which project to use. Note that we're passing the path to
|
||||
the ``admin`` settings, not the ``main`` settings. That's because this is the
|
||||
admin site, which has slightly different settings.
|
||||
|
||||
Also, if you've manually altered your ``PYTHONPATH`` to put your project on it,
|
||||
you'll need to tell mod_python::
|
||||
|
||||
PythonPath "['/path/to/project'] + sys.path"
|
||||
|
||||
You can also add directives such as ``PythonAutoReload Off`` for performance.
|
||||
See the `mod_python documentation`_ for a full list of options.
|
||||
|
||||
When you've done that, restart Apache and go to /admin/ on your domain. You
|
||||
should see the admin's login screen:
|
||||
Now, open a Web browser and go to "/admin/" on your domain. You should see the
|
||||
admin's login screen:
