getting database connection error..trying to install WP on localhost using XAMPP

Hi guys,

Please help me out here..new with this WP thing. I am on a Mac.
Apache web server and MySQL are both running…
getting database connection error as follows..

Warning: mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known in /Applications/XAMPP/xamppfiles/htdocs/local-wordpress/wp-includes/wp-db.php on line 1488

Warning: mysqli_real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known in /Applications/XAMPP/xamppfiles/htdocs/local-wordpress/wp-includes/wp-db.php on line 1488

I am hoping someone can see what I am not..

Here is how my config file looks like.

// ** MySQL settings – You can get this info from your web host ** //
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘WPsite1’);

/** MySQL database username */
define(‘DB_USER’, ‘root’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘’);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

/** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);

/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);

Thanks
