Multiple wordpress install problem

Hi there, I have been working on multiple installs of wordpress on two systems, but alas I have hit a snag. I have set on up with no problems, but I have had to rebuild the other system completely.

I have recently hit a new problem, after auto generating the scripts using shell scripts everytime I generate a new blog it says it cannot access a database which isnt there… well.. the thing is there is NO part of the config file (or in fact ANY file) which points at this non-existant database, the wp-config.php file:

<?php
define('DB_NAME', 'media_steve');
define('DB_USER', '******');
define('DB_PASSWORD', '******');
define('DB_HOST', 'localhost');
$table_prefix  = 'cheese_';
define('WPLANG', '');
define('ABSPATH', '/srv/www/farm/sb/');
require_once(ABSPATH.'wp-settings.php');
?>

and it says:

Error establishing a database connection

Yet it is there, the username and password are correct, the prefix is 100% correct, the path is correct. Permissions are all set up, I have even tried it with the root password.

If I then goto the wp-admin dir on Firefox I get:

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the media_2012 database.

* Are you sure it exists?
* Does the user blogs have permission to use the media_2012 database?
* On some systems the name of your database is prefixed with your username, so it would be like username_media_2012. Could that be the problem?

If you don’t know how to setup a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.

There is no 2012!! any ideas?
