Directadmin hasn’t a one-click login button for access to PhpMyAdmin like other panels (cPanel, Plesk) as default. But, it has been added as a feature a while ago. Normally, you should browse http://YOURSERVERIP:2222/phpMyAdmin/
and type exact credentials to access the database.
How to enable this feature?
Firstly, you should connect to SSH with your root credentials. Then, run the below commands for enable it.
/usr/local/directadmin/directadmin set one_click_pma_login 1
service directadmin restart
Now, you can access your MySQL database in Directadmin without typing any credentials.
