birdhousebuilder.recipe.adagucserver

Introduction

birdhousebuilder.recipe.adagucserver is a Buildout recipe to install and configure Adagucserver with Anaconda. Adagucserver is an implementation of a Web Map Service (WMS). Adagucserver 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 adagucserver package from a conda channel in a conda environment named birdhouse. The location of the birdhouse environment is .conda/envs/birdhouse. It deploys a Supervisor configuration for Adagucserver in ~/.conda/envs/birdhouse/etc/supervisor/conf.d/adagucserver.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 deploys a Nginx site configuration for Adagucserver. The configuration will be deployed in ~/.conda/envs/birdhouse/etc/nginx/conf.d/adagucserver.conf. Nginx can be started with ~/.conda/envs/birdhouse/etc/init.d/nginx start.

By default Adagucserver will be available on http://localhost:9002?service=WMS&version=1.3.0&request=GetCapabilities.

The recipe depends on:

• birdhousebuilder.recipe.conda
• birdhousebuilder.recipe.supervisor
• 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

title

Title of the Web Map Service. Default: Birdhouse ADAGUC WMS

abstract

Description of the Web Map Service. Default: ADAGUC Web Map Service used in Birdhouse

port

Port used by the Adaguc WMS service. Default: 9002

data_dir

Path to the data directory with NetCDF files. Default: ~/.conda/envs/birdhouse/var/lib/pywps/outputs

enablecache

Enabled caching of WMS requests. Default: false

Example usage

The following example buildout.cfg installs Adagucserver with Anaconda:

[buildout]
parts = adaguc

anaconda-home = /home/myself/anaconda

[adaguc]
recipe = birdhousebuilder.recipe.adagucserver
port = 9002

After installing with Buildout start the Adagucserver WMS 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 adagucserver is running
$ less var/log/adaguc.log  # check log file
