# Setup MySQL database for PowerDNS-Admin This guide will show you how to prepare a MySQL or MariaDB database for PowerDNS-Admin. We assume the database is installed per your platform's directions (apt, yum, etc). ## Setup database: Connect to the database (Usually using `mysql -u root -p` - then enter your MySQL/MariaDB root users password if applicable), then enter the following: ``` CREATE DATABASE `powerdnsadmin` CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; GRANT ALL PRIVILEGES ON `powerdnsadmin`.* TO 'pdnsadminuser'@'localhost' IDENTIFIED BY 'YOUR_PASSWORD_HERE'; FLUSH PRIVILEGES; quit ``` - If your database server is located on a different machine then change 'localhost' to '%' - Replace YOUR_PASSWORD_HERE with a secure password. ## Known issues: Problem: If you plan to manage large zones, you may encounter some issues while applying changes. This is due to PowerDNS-Admin trying to insert the entire modified zone into the column history.detail. Using MySQL/MariaDB, this column is created by default as TEXT and thus limited to 65,535 characters. Solution: Convert the column to MEDIUMTEXT: ``` USE powerdnsadmin; ALTER TABLE history MODIFY detail MEDIUMTEXT; ```
