Installing the API behind mod_wsgi

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

app.wsgi

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

etc/apache2/aodh

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

../../../etc/apache2/aodh

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 a appropriate user on your server. In many installations aodh will be correct.

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

   $ a2ensite aodh
   $ service apache2 reload

   On rpm-based systems:

   $ service httpd reload

Limitation

As Aodh is using Pecan and Pecan's DebugMiddleware doesn't support multiple processes, there is no way to set debug mode in the multiprocessing case. To allow multiple processes the DebugMiddleware may be turned off by setting pecan_debug to False in the api section of aodh.conf.

For other WSGI setup you can refer to the pecan deployment documentation. .. _`pecan deployment`: http://pecan.readthedocs.org/en/latest/deployment.html#deployment
