In-production deployment has been tested using Apache2 and mod_wsgi. For other deployment scenarios, please consult the pyramid deployment documentation.

Deploying with Apache2 & mod_wsgi

To deploy the Experiment Support System via Apache2 and mod_wsgi add the following settings to the VirtualHost configuration:

WSGIDaemonProcess pyquest user=www-data group=www-data processes=1 threads=10 python-path=/path/to/virtualenv/lib/python2.7/site-packages
WSGIScriptAlias /pyquest /path/to/the/application.wsgi
<Location /pyquest>
    WSGIProcessGroup pyquest

Note: Leave the processes value at 1. Use the threads option to specify how many parallel requests to support.

Then create the following script to to run the application via WSGI. Adapt it by replacing the paths with the paths to where the Experiment Support System is installed:

import os
import site
import sys

# Remember original sys.path.
prev_sys_path = list(sys.path)


# Reorder sys.path so new directories at the front.
new_sys_path = []
for item in list(sys.path):
    if item not in prev_sys_path:
sys.path[:0] = new_sys_path

from pyramid.paster import get_app
from paste.script.util.logging_config import fileConfig
application = get_app('/path/to/the/application/pyquest.ini', 'main')
