PhpMyAdmin
From Gentoo Linux Wiki
phpMyAdmin is an open source tool written in PHP intended to handle the administration of MySQL over the Internet. Currently it can create and drop databases, create/drop/alter tables, delete/edit/add fields, execute any SQL statement, manage users and permissions, and manage keys on fields.
[edit] Install
Install phpMyAdmin by executing:
emerge -av phpmyadmin
You'll need to grant some rights for it to let it do its magic.
mysql -u root -p < /usr/share/webapps/phpmyadmin/<VERSION>/sqlscripts/mysql/<VERSION>_create.sql
