@unit9: If you’re still wondering, to create a database on the (gs) Grid-Service platform, you log in to your AccountCenter ( https://ac.mediatemple.net ), click on “Admin” for your domain from the main dashboard page, and go to “Manage Databases”. You will then see a tab titled “Add a Database”. From here, you can create either a MySQL or PostgreSQL database. The “Global Settings” tab will reveal to you the username, password, and database hostname to use.
Note: You will need to use a specific hostname for your database on the (gs) Grid-Service. Using ‘localhost’ will not work. The hostname is something along the lines of ‘internal-db.s<site_number>.gridserver.com’, where ‘<site_number>’ is replaced by your actual site number on the Grid.
Hope this helps!
