This is the error message coming directly from PHP/MySQL when attempting to connect to the database. It suggests that the database wouldn't respond to the connection request.
Possible causes of not responding:
- MySQL isn't running
- MySQL Connector for PHP isn't installed or is misconfigured
- port 3306 is blocked
- MySQL was configured for other than the default port #3306
- firewall service blocking communication: http://forums.mysql.com/read.php?11,...2171#msg-22171
- invalid server address supplied
