Connecting Flask to Apache

When exploring the cosmos of python powered web frameworks it’s easy to get lost due to fast moving versions. Recently we had a lot of difficulty getting Flask connected via a WSGI script on Apache. This seems to be due to needing the object factory to be called specifically rather than relying on the module namespace to do the work for us, there doesn’t seem to be much help online about this yet. We’re also running python in a virtualenv so the working wsgi script looks like this:

import sys
import logging
import os

PROJECT_DIR = "/var/www/yourflasksite/"
activate_this = os.path.join(PROJECT_DIR, 'bin', 'activate_this.py')
execfile(activate_this, dict(__file__=activate_this))

from app import create_app
application=create_app(os.getenv('FLASK_CONFIG') or 'default')
application.secret_key = 'your site's key'

For completeness, here is the apache config that starts it up:

<VirtualHost *:80>
    ServerName your.url
    WSGIScriptAlias / /var/www/yourflasksite/yoursite.wsgi
    <Directory /var/www/yourflasksite/app>
	Order allow,deny
        Allow from all
    Alias /static /var/www/yourflasksite/app/static
    <Directory /var/www/yourflasksite/app/static/>
        Order allow,deny
        Allow from all
    ErrorLog ${APACHE_LOG_DIR}/yourflasksite-error.log
    LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/yourflasksite-access.log
