Bonjour à tous j'utilise deux serveurs , server web PHP Apache (dans le virtual box centos7 ) et l'autre server base de données ( centos 7)
J'ai  copié les dossiers GLPI 4.2 dans  /var/www/html du  server web PHP Apache
Je voudrais  connecter mon server web PHP Apache avec le server base de données ,je ne sais pas  quel fichier dois-je paramétrer
 
J'ai ouvert le fichier config.php dans   /var/www/html/glpi/inc
 
Voici le code
<?php
