Running a local Zaqar server with MongoDB
-----------------------------------------

**Note:** These instructions are for running a local instance of Zaqar and
not all of these steps are required. It is assumed you have `MongoDB`_
installed and running.

1. From your home folder create the ``~/.zaqar`` folder and clone the repo::

    $ cd
    $ mkdir .zaqar
    $ git clone https://github.com/openstack/zaqar.git

2. Copy the Zaqar config files to the directory ``~/.zaqar``::

    $ cp zaqar/etc/zaqar.conf.sample ~/.zaqar/zaqar.conf
    $ cp zaqar/etc/logging.conf.sample ~/.zaqar/logging.conf

3. Find ``[drivers]`` section in ``~/.zaqar/zaqar.conf``
   and specify to use mongodb storage::

    storage = mongodb

   Then find the ``[drivers:storage:mongodb]`` section
   and modify the URI to point to your local mongod instance::

    uri = mongodb://$MONGODB_HOST:$MONGODB_PORT

   By default, you will have::

    uri = mongodb://127.0.0.1:27017

4. For logging, find the ``[DEFAULT]`` section in
   ``~/.zaqar/zaqar.conf`` and modify as desired::

    log_file = server.log

5. Change directories back to your local copy of the repo::

    $ cd zaqar

6. Run the following so you can see the results of any changes you
   make to the code without having to reinstall the package each time::

    $ pip install -e .

7. Start the Zaqar server with logging level set to INFO so you can see
   the port on which the server is listening::

    $ zaqar-server -v

8. Test out that Zaqar is working by creating a queue::

    $ curl -i -X PUT http://127.0.0.1:8888/v1/queues/samplequeue -H
    "Content-type: application/json"

You should get an **HTTP 201** along with some headers that will look
similar to this::

    HTTP/1.0 201 Created
    Date: Fri, 25 Oct 2013 15:34:37 GMT
    Server: WSGIServer/0.1 Python/2.7.3
    Content-Length: 0
    Location: /v1/queues/samplequeue

Running tests
-------------

First install additional requirements::

    pip install tox

And then run tests::

    tox -e py27
