Introduction
************

``birdhousebuilder.recipe.pycsw`` is a `Buildout`_ recipe to install and configure `pycsw`_ with `Anaconda`_. `pycsw`_ is a Python implementation of a `Catalog Service for the Web`_ (CSW). ``pycsw`` will be deployed as a `Supervisor`_ service and is available on a `Nginx`_ web server.

This recipe is used by the `Birdhouse`_ project.

Usage
*****

The recipe requires that Anaconda is already installed. It assumes that the default Anaconda location is in your home directory ``~/anaconda``. Otherwise you need to set the ``ANACONDA_HOME`` environment variable or the Buildout option ``anaconda-home``.

It installs the ``pycsw`` package from a conda channel in a conda environment named ``birdhouse``. The location of the birdhouse environment is ``.conda/envs/birdhouse``. It setups a `pycsw`_ database (``sqlite``) in ``~/.conda/envs/birdhouse/var/lib/pycsw``. It deploys a `Supervisor`_ configuration for ``pycsw`` in ``~/.conda/envs/birdhouse/etc/supervisor/conf.d/pycsw.conf``. Supervisor can be started with ``~/.conda/envs/birdhouse/etc/init.d/supervisor start``.

The recipe will install the ``nginx`` package from a conda channel and deploy a Nginx site configuration for ``pycsw``. The configuration will be deployed in ``~/.conda/envs/birdhouse/etc/nginx/conf.d/pycsw.conf``. Nginx can be started with ``~/.conda/envs/birdhouse/etc/init.d/nginx start``.

By default ``pycsw`` will be available on http://localhost:8082/csw?service=CSW&version=2.0.2&request=GetCapabilities.

The recipe depends on ``birdhousebuilder.recipe.conda``, ``birdhousebuilder.recipe.supervisor`` and ``birdhousebuilder.recipe.nginx``.

Supported options
=================

The recipe supports the following options:

``anaconda-home``
Buildout option with the root folder of the Anaconda installation. Default: ``$HOME/anaconda``.
The default location can also be set with the environment variable ``ANACONDA_HOME``. Example::

export ANACONDA_HOME=/opt/anaconda

Search priority is:

1. ``anaconda-home`` in ``buildout.cfg``
2. ``$ANACONDA_HOME``
3. ``$HOME/anaconda``

``hostname``
The hostname of the pycsw service (nginx). Default: ``localhost``

``port``
The port of the pycsw service (nginx). Default: ``8082``


Example usage
=============

The following example ``buildout.cfg`` installs ``pycsw`` with Anaconda::

[buildout]
parts = pycsw

anaconda-home = /opt/anaconda

[pycsw]
recipe = birdhousebuilder.recipe.pycsw
hostname = localhost
port = 8082

After installing with Buildout start the ``pycsw`` service with::

$ cd /home/myself/.conda/envs/birdhouse
$ etc/init.d/supervisord start # start|stop|restart
$ etc/init.d/nginx start # start|stop|restart
$ bin/supervisorctl status # check that pycsw is running
$ less var/log/pycsw/pycsw.log # check log file

Open your browser with the following URL::

http://localhost:8082/csw?service=CSW&version=2.0.2&request=GetCapabilities
