For more detailed information about WSGI, please visit their website <http://wsgi.org/wsgi/>_. In general WSGI is preferred over mod_python mode.
Install mod_wsgi for Apache server (if you are using it)
Locate webservices/wsgi/wsgiwps.py which provides the WSGI interface
Configure Apache server to something similar as:
SetEnv PYTHONPATH /usr/local/src/pywps/ # is not installed the 'clean' way
SetEnv PYWPS_CFG /usr/local/src/pywpsworkdir/pywps.cfg
SetEnv PYWPS_PROCESSES /usr/local/src/pywpsworkdir/processes
<Directory /usr/local/src/pywps/>
Order allow,deny
Allow from all
</Directory>
WSGIScriptAlias /wps /usr/local/src/pywps/webservices/wsgi/wpswsgi.py
