The error is Drupal saying it can't see the database. Depending on your hosting arrangement for the live server this may or may not be on the same server as the Drupal installation.(It's most likely on another server though)

Have you uploaded the database? - Most commonly done by producing a SQL dump from the local development DB and importing it into the live one.

Just copying the Drupal files is only half of the story.

you have to change the db_url like this

 * Database URL format:
 *   $db_url = 'mysql://username:password@localhost/databasename';
 *   $db_url = 'mysqli://username:password@localhost/databasename';
 *   $db_url = 'pgsql://username:password@localhost/databasename';;

you have also to put your mysql in the live DB :)
