Voeg in phpmyadmin de 2e instantie toe. Let op de host moet 127.0.0.1 zijn ipv localhost.

Vergeet ook niet de juiste port aan te geven!!

#  vi /etc/phpmyadmin/config.inc.php
$i++;
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'cookie';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysqli if your server has it */
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['port'] = '3308';

that’s it
