CloudSQL

Google Cloud SQL is a MySQL database that lives in Google's cloud
Easy to use, doesn't require any software installation or maintenance

Create the instance of CloudSQL in https://console.developers.google.com/

You can use Mysql Clients
mysql -h IPAddress -uroot -p
create database namedb;


config the database in settings.py

DATABASES = {
        'default': {
            'ENGINE': 'google.appengine.ext.django.backends.rdbms',
            'INSTANCE': 'your-app-id:your-instance',
            'NAME': 'namedb',
            'USER': 'root',
        }
    } 

Ensure that the django and google packages would be found when running manage.py
export PYTHONPATH="$PYTHONPATH:/home/user/google_appengine:
/home/user/google_appengine/lib/django_1_5"
