OK, Trouvé lol

Salut a tous...
Petit pb, debutant j'essaye de me connecter a une base qui marche a merveille mais dès que j'utilise mes données de connection ca marche plus

Pg Includeserge.php
<?php
define("host", "xxxxxx");
define("user", "yyyyyyy");
define("db", "zzzzzzz");
define("pass", "ddddddd");
?>

Mon pg:
<?

include("configserge.php");

// connection à la DB
$link = mysql_connect (host,user,pass) or die ('Erreur : '.mysql_error() );

Voila il me fait erreur:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /homez.209/anselcon/www/table01.php on line 35
