PhpMyAdmin is available as an addon. To install, ensure you have first secured MySQL. Then execute the installation script:
Downloading the phpmyadmin addon
cd /usr/games/minecraft/addons ./phpmyadmin.sh
mbstring module dependency
On MineOS installations earlier than 0.4.8, php-mbstring was not included in the install. Since PhpMyAdmin operates better with this module, you can install it with another add-on. Versions 0.4.8 and beyond have this module installed by default.
cd /usr/games/minecraft/addons ./mbstring.sh
Enable PHP for PhpMyAdmin
Enable PHP script execution in /var/www/hiawatha/phpmyadmin by enabling CGI.
PhpMyAdmin is now accessible via https://ip-address/phpmyadmin. Note: HTTPS is required for PhpMyAdmin.
