A Buildout recipe to install and configure PyWPS Web Processing Service with Anaconda.
Project description
Introduction
birdhousebuilder.recipe.pywps is a Buildout recipe to install and configure PyWPS with Anaconda. PyWPS is a Python implementation of a Web Processing Service (WPS). PyWPS 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 pywps package from a conda channel in a conda environment named birdhouse. The location of the birdhouse environment is .conda/envs/birdhouse. It setups a PyWPS output folder in ~/.conda/envs/birdhouse/var/lib/pywps. It deploys a Supervisor configuration for PyWPS in ~/.conda/envs/birdhouse/etc/supervisor/conf.d/pywps.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 PyWPS. The configuration will be deployed in ~/.conda/envs/birdhouse/etc/nginx/conf.d/pywps.conf. Nginx can be started with ~/.conda/envs/birdhouse/etc/init.d/nginx start.
By default PyWPS will be available on http://localhost:8091/wps?service=WPS&version=1.0.0&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:
anaconda-home in buildout.cfg
$ANACONDA_HOME
$HOME/anaconda
- hostname
The hostname of the PyWPS service (nginx). Default: localhost
- port
The port of the PyWPS service (nginx). Default: 8091
- sites
The name of your WPS project (used for config names and folder path).
- processesPath
Path the PyWPS processes.
- title
Title used for your WPS service.
- abstract
Description of your WPS service.
Example usage
The following example buildout.cfg installs PyWPS with Anaconda:
[buildout]
parts = pywps
anaconda-home = /home/myself/anaconda
[pywps]
recipe = birdhousebuilder.recipe.pywps
sites = myproject
hostname = localhost
port = 8091
# pywps options
processesPath = ${buildout:directory}/myproject/processes
title = MyProject ...
abstract = MyProject does ...
After installing with Buildout start the PyWPS service with:
$ cd /home/myself/anaconda $ 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/pywps/myproject.log # check log file
Open your browser with the following URL:
http://localhost:8091/wps?service=WPS&version=1.0.0&request=GetCapabilities
