Running PyCK Applications with Apache Mod WSGI and VirtualenvΒΆ

Assuming you have followed the Installation section and created a virtualenv named pyckenv, we’ll now setup Apache to use this virtualenv alongwith mod_wsgi for deploying our pyck applications. You should already have installed mod_wsgi for Apache.

  1. Edit Apache’s mod_wsgi configuration file normally present under /etc/apache2/mods-available/wsgi.conf and place these two lines in it:

    WSGIPythonHome /var/pyck/pyckenv
    WSGIPythonEggs /var/pyck/eggs_cache

    Remember to put them inside the <IfModule mod_wsgi.c> section and adjust the path to point to your virtualenv for pyck

  2. Create the eggs_cache folder and make give it full read/write/execute permissions:

    mkdir /var/pyck/eggs_cache
    chmod 777 /var/pyck/eggs_cache
  3. Restart Apache:

    sudo apache2ctl restart
  4. Create your application (assuming its under /var/www):

    pcreate -t pyck wsgi_test
  5. Make it ready for deployment:

    cd wsgi_test
    python develop
    python install
  6. Create the wsgi file for use with mod_wsgi, lets name it myapp.wsgi:

    from pyramid.paster import get_app
    import os
    here = os.path.dirname(__file__)
    application = get_app(here + '/development.ini', 'main')
    #application = get_app(here + '/production.ini', 'main')  #for production
  7. Make the myapp.wsgi file executable:

    chmod 755 myapp.wsgi
  8. Create .htaccess file in your application folder and put the following contents in it:

    Options ExecCGI FollowSymLinks
    DirectoryIndex myapp.wsgi
    RewriteEngine on
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ myapp.wsgi/$1  [L]
    AddHandler cgi-script .cgi
    AddHandler wsgi-script .wsgi
    Order allow,deny
    Allow from all

Thats all now you can test your application at: http://localhost/wsgi_test/
