 Using MongoDB
===============

.. _broker-mongodb-installation:

Installation
============

For the MongoDB support you have to install additional dependencies.
You can install both Celery and these dependencies in one go using
either the `celery-with-mongodb`_, or the `django-celery-with-mongodb` bundles::

    $ pip install -U celery-with-mongodb

.. _`celery-with-mongodb`:
    http://pypi.python.org/pypi/celery-with-mongodb
.. _`django-celery-with-mongodb`:
    http://pypi.python.org/pypi/django-celery-with-mongodb

.. _broker-mongodb-configuration:

Configuration
=============

Configuration is easy, set the transport, and configure the location of
your MongoDB database::

    BROKER_URL = "mongodb://localhost:27017/database_name"

Where the URL is in the format of::

    mongodb://userid:password@hostname:port/database_name

The host name will default to ``localhost`` and the port to 27017,
and so they are optional.  userid and password are also optional,
but needed if your MongoDB server requires authentication.
