Installing the API behind mod_wsgi

Zun comes with a few example files for configuring the API service to run behind Apache with mod_wsgi.

app.wsgi

The file zun/api/app.wsgi sets up the V2 API WSGI application. The file is installed with the rest of the zun application code, and should not need to be modified.

etc/apache2/zun.conf

The etc/apache2/zun.conf file contains example settings that work with a copy of zun installed via devstack.

../../../etc/apache2/zun.conf

1. On deb-based systems copy or symlink the file to /etc/apache2/sites-available. For rpm-based systems the file will go in /etc/httpd/conf.d.

2. Modify the WSGIDaemonProcess directive to set the user and group values to an appropriate user on your server. In many installations zun will be correct. Modify the WSGIScriptAlias directive to set the path of the wsgi script. If you are using devstack, the value should be /opt/stack/zun/zun/api/app.wsgi. In the ErrorLog and CustomLog directives, replace %APACHE_NAME% with apache2.

3. Enable the zun site. On deb-based systems:

   $ a2ensite zun
   $ service apache2 reload

   On rpm-based systems:

   $ service httpd reload
