Running a TurboGears under Apache with mod_wsgi

mod_wsgi is an Apache module developed by Graham Dumpleton. It allows WSGI programs to be served using the Apache web server.

This guide will outline broad steps that can be used to get a TurboGears application running under Apache via mod_wsgi.

1. The tutorial assumes you have Apache already installed on your system. If you do not, install Apache 2.X for your platform in whatever manner makes sense.

2. Once you have Apache installed, install mod_wsgi. Use the (excellent) installation instructions for your platform into your system’s Apache installation.

3. Create a virtualenvironment with the specific TurboGears version your application depends on installed.

   $ virtualenv /var/tg2env
   $ /var/tg2env/bin/pip install -f http://tg.gy/230 tg.devtools
   

4. Activate the virtualenvironment

   $ source /var/tg2env/bin/activate
   (tg2env)$ #virtualenv now activated
   

5. Install your TurboGears application.

   (tg2env)$ cd /var/www/myapp
   (tg2env)$ python setup.py develop
   

6. Within the application director, create a script named app.wsgi. Give it these contents:

   APP_CONFIG = "/var/www/myapp/myapp/production.ini"
   
   #Setup logging
   import logging
   logging.config.fileConfig(APP_CONFIG)
   
   #Load the application
   from paste.deploy import loadapp
   application = loadapp('config:%s' % APP_CONFIG)
   

7. Edit your Apache configuration and add some stuff.

   <VirtualHost *:80>
       ServerName www.site1.com
   
       WSGIProcessGroup www.site1.com
       WSGIDaemonProcess www.site1.com user=www-data group=www-data threads=4 python-path=/var/tg2env/lib/python2.7/site-packages
       WSGIScriptAlias / /var/www/myapp/app.wsgi
   
       #Serve static files directly without TurboGears
       Alias /images /var/www/myapp/myapp/public/images
       Alias /css /var/www/myapp/myapp/public/css
       Alias /js /var/www/myapp/myapp/public/js
   
       CustomLog logs/www.site1.com-access_log common
       ErrorLog logs/www.site1.com-error_log
   </VirtualHost>
   

8. Restart Apache

   $ sudo apache2ctl restart
   

9. Visit http://www.site1.com/ in a browser to access the application.

See the mod_wsgi configuration documentation for more in-depth configuration information.
