phpMyAdmin Setup Interface
phpMyAdmin can be configured through it’s usable setup interface (something like http://localhost/phpmyadmin/setup). In most cases, you’ll have to authenticate first to access the panel. The credentials for this authentication can be found in /etc/phpmyadmin/htpasswd.setup file. You’ll probably have to generate a password before doing anything else. You can do that online. I tend to use this website.
Note that I’m using Ubuntu 10.04 and phpMyAdmin version 3.3.2deb1.
