Commands starting by ``$`` must be run as ``ponytracker`` user.


Requirements
************

You need python. Version 2.7, 3.2 or 3.4 (and probably others) are fine.

This installation guide install PonyTracker in a virtualenv.
The corresponding packages names are ``python-virtualenv`` for python 2
and ``python3-virtualenv`` for python 3 (at least under Debian).

You need also ``supervisord`` to lunch PonyTracker.
You can install it with the package with the same name.


Installation
************

Be sure ``/srv/www`` exists::

  # mkdir -p /srv/www

Create a dedicated user::

  # useradd -r -m -d /srv/www/ponytracker ponytracker

The following commands are executed as ``ponytracker`` user::

  # su ponytracker
  $ cd /srv/www/ponytracker

Create ``log`` and ``www`` directories::

  $ mkdir log www

Clone the git repository and switch to the release branch::

  $ git clone http://github.com/bouttier/ponytracker
  $ cd ponytracker # we are now in /srv/www/ponytracker/ponytracker
  $ git checkout release

Copy the example configuration file::

  $ cp ponytracker/local_settings.py.example ponytracker/local_settings.py

Set the ``SECRET_KEY`` value.
You can generate a secret key with ``openssl``::

  $ openssl rand -base64 32

If you want email notifications, set ``BASE_URL``, ``EMAIL_HOST`` (smtp relay)
and ``FROM_ADDR``.

If you want to use an over database than the default sqlite, set ``DATABASES``.
You can found the syntaxe in the `django documentation`_.

.. _django documentation: https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-DATABASES

Set the static directory::

  STATIC_ROOT = '/srv/www/ponytracker/www/static'

Create a virtualenv and enter in it::

  $ virtualenv env
  $ source env/bin/activate

Install requirements::

  $ pip install -r requirements.txt
  $ pip install gunicorn

Initialize database tables::

  $ python manage.py migrate

Create a account for the administrator::

  $ python manage.py createsuperuser

Collect static files in the ``STATIC_DIR``::

  $ python manage.py collecstatic --settings=ponytracker.local_settings

Create the new file ``/etc/supervisor/conf.d/ponytracker.conf`` contening::

  [program:ponytracker]
  command=/srv/www/ponytracker/ponytracker/env/bin/gunicorn ponytracker.wsgi
  directory=/srv/www/ponytracker/ponytracker
  environment=PATH="/srv/www/ponytracker/ponytracker/env/bin"
  user=ponytracker
  autostart=true
  autorestart=true
  redirect_stderr=true

Modify the file ``ponytracker/wsgi.py`` to use local settings instead of
default settings::

  os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ponytracker.local_settings")

In order to do not have conflict during an update, you can tell `git` to ignore
this modification::

  $ git update-index --assume-unchanged ponytracker/wsgi.py

Start ``supervisord`` to run the server::

  $ service supervisor start

You can verify that the server is listening on ``localhost`` on port ``8000``::

  $ lsof | grep LISTEN | grep ponytracker

You now need to install a real web server as a front-end.
This documentation show sample configuration files for both `apache` and
`nginx`.
