Deploying GeoDjango
===================

.. warning::

    GeoDjango uses the GDAL geospatial library which is
    not thread safe at this time.  Thus, it is *highly* recommended
    to not use threading when deploying -- in other words, use a
    an appropriate configuration of Apache or the prefork method
    when using FastCGI through another Web server.

Apache
======
In this section there are some example ``VirtualHost`` directives for
when deploying using either ``mod_python`` or ``mod_wsgi``.  At this
time, we recommend ``mod_wsgi``, as it is now officially recommended
way to deploy Django applications with Apache.  Moreover, if
``mod_python`` is used, then a prefork version of Apache must also be
used.  As long as ``mod_wsgi`` is configured correctly, it does not
matter whether the version of Apache is prefork or worker.

.. note::

    The ``Alias`` and ``Directory`` configurations in the examples
    below use an example path to a system-wide installation folder of Django.
    Substitute in an appropriate location, if necessary, as it may be
    different than the path on your system.

``mod_wsgi``
------------

Example::

    <VirtualHost *:80>
      WSGIDaemonProcess geodjango user=geo group=geo processes=5 threads=1
      WSGIProcessGroup geodjango
      WSGIScriptAlias / /home/geo/geodjango/world.wsgi

      Alias /media/ "/usr/lib/python2.5/site-packages/django/contrib/admin/media/"
      <Directory "/usr/lib/python2.5/site-packages/django/contrib/admin/media/">
        Order allow,deny
        Options Indexes
        Allow from all
        IndexOptions FancyIndexing
      </Directory>

    </VirtualHost>

.. warning::

    If the ``WSGIDaemonProcess`` attribute ``threads`` is not set to ``1``, then
    Apache may crash when running your GeoDjango application.  Increase the
    number of ``processes`` instead.

For more information, please consult Django's
:doc:`mod_wsgi documentation </howto/deployment/modwsgi>`.

``mod_python``
--------------

.. warning::
    Support for mod_python will be deprecated in a future release of Django. If
    you are configuring a new deployment, you are strongly encouraged to
    consider using :doc:`mod_wsgi </howto/deployment/modwsgi>` or any of the
    other :doc:`supported backends </howto/deployment/index>`.

Example::

    <VirtualHost *:80>

      <Location "/">
        SetHandler mod_python
        PythonHandler django.core.handlers.modpython
        SetEnv DJANGO_SETTINGS_MODULE world.settings
        PythonDebug On
        PythonPath "['/var/www/apps'] + sys.path"
      </Location>

      Alias /media/ "/usr/lib/python2.5/site-packages/django/contrib/admin/media/"
      <Location "/media">
        SetHandler None
      </Location>

    </VirtualHost>

.. warning::

   When using ``mod_python`` you *must* be using a prefork version of Apache, or
   else your GeoDjango application may crash Apache.

For more information, please consult Django's
:doc:`mod_python documentation </howto/deployment/modpython>`.
