Craft can't connect to the database (using ec2)
So a couple of things:


It's probably not a great idea to connect as root -- it'd be better to create a mysql user that has access only to that db.
Make sure that the db you're connecting to is indeed named Craft (case may count here, I'm not sure)
The table_prefix looks wrong to me; probably it should be just: 'tablePrefix' =&gt; 'craft',
