how to fix it...everything is fine including config.php but still this error is coming....

Either host has not permission-ed the mysql data folder correctly (usually caused when the datastore folder of the mysql database is transferred over)

fix only root can fix:

chown -R mysql:mysql foldername

Or the actual database file is missing.
