    Alias /static/ /home/ubuntu/app/boomset/static_root/
    <Directory /home/ubuntu/app/boomset/static_root>
            Require all granted
    </Directory>
    WSGIDaemonProcess boomset.com python-path=/home/ubuntu/app/boomset:/home/ubuntu/app/venv/lib/python2.7/site-packages
    WSGIProcessGroup boomset.com
    WSGIScriptAlias / /home/ubuntu/app/boomset/boomset/wsgi.py

                    Require all granted
            </Files>
