Is the sql server running? Are you able to login via phpmyadmin or shell directly to the database with the credentials the forum software uses?

Database: MySQL
SQL Error: 1045 - Access denied for user 'USERNAME'@'HOSTNAME' (using password: YES)
Query: [READ] Unable to connect to MySQL server
Information: This occurs when you are using MySQL and the database password is incorrect in ./inc/config.php. To fix this, open ./inc/config.php and check the entry for $config['database']['password']. If you do not know what needs to be here, contact your host provider.
