If you are trying to upload a WordPress site to OpenShift you will have to make the following adjustments to your wp-config.php file:

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME',$_ENV['OPENSHIFT_GEAR_NAME']);

/** MySQL database username */
define(‘DB_USER’, $_ENV[‘OPENSHIFT_MYSQL_DB_USERNAME’]);

/** MySQL database password */
define(‘DB_PASSWORD’, $_ENV[‘OPENSHIFT_MYSQL_DB_PASSWORD’]);


/** MySQL hostname */
define('DB_HOST', $_ENV['OPENSHIFT_MYSQL_DB_HOST'] . ':' . $_ENV['OPENSHIFT_MYSQL_DB_PORT']);

This will help WordPress to use the environment variables that OpenShift setup to connect to MySQL.
