Installing phpMyAdmin

phpMyAdmin is a commonly used database administration tool for MySQL. It is a web-based application, like Webmin itself, but dedicated to all tasks related to the administration of a MySQL server. It's easy to use and can be a helpful tool for your database users and administrators.

Note

System packages are configured to run phpMyAdmin on Apache. The Apache web server and PHP are installed as package dependencies.
