Considering the fact i know nothing about your setup. And assuming you have a database server up and running. It's probably that you have quoted the constants in the mysql_connect call
Change
$link = mysql_connect('DB_HOST','DB_USER','DB_PASSWORD');
to
$link = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);
