Apache configuration

1. Enable WSGI extension

2. Add configuration:

   WSGIDaemonProcess pywps user=user group=group processes=2 threads=5
   WSGIScriptAlias /pywps/path/to/www/htdocs/wps/pywps.wsgi

   Order deny,allow
   Allowfrom all
   </Directory>

3. Create wsgi file:

   #!/usr/bin/env python3importsyssys.path.append('/path/to/src/pywps/')
   importpywpsfrompywps.appimportService, WPS, Processdefpr1():
   """This is the execute method of the process """passapplication=Service(processes=[Process(pr1)])

4. Run via web browser

   http://localhost/pywps/?service=WPS&request=GetCapabilities&version=1.0.0

5. Run in command line:

   curl 'http://localhost/pywps/?service=WPS&request=GetCapabilities&version=1.0.0'

Issues

On Windows PyWPS does not support multiprocessing which is used when making requests storing the response document and updating the status to displaying to the user the progression of a process.
