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.

Install required packages:

Red-hat based systems:

yum install MariaDB-shared mariadb-devel mysql-community-devel

If you use MariaDB ( from MariaDB repositories )

Debian based systems:

apt install libmysqlclient-dev

Install python packages:

pip3 install mysqlclient==2.0.1

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;
