Hi,
are there any error-messages while connecting to MySQL?
(Maybe you have to enable displaying errors with the normal php output - Display_Errors in the PHP.INI)
--restart the Apache after saving any changes to the php.in
A (good) GUI for MySQL is phpMyAdmin. phpMyAdmin is part of OpenSuse. You can install it with YaST.
phpMyAdmin is Browserbased. To start it enter
http://hostname/phpMyAdmin
But you have to provide the usernaem and password to access MySQL
