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:
1. ivan@ubuntu:~$ `mysql -u root -p` (then enter your MySQL/MariaDB root users password)
2. mysql> `CREATE DATABASE powerdnsadmin CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;`
3. mysql> `GRANT ALL PRIVILEGES ON powerdnsadmin.* TO 'pdnsadminuser'@'%' IDENTIFIED BY 'p4ssw0rd';`
4. mysql> `FLUSH PRIVILEGES;`
5. mysql> `quit`
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
```
## Known issues:
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.
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;`
Solution: Convert the column to MEDIUMTEXT:
```
USE powerdnsadmin;
ALTER TABLE history MODIFY detail MEDIUMTEXT;
```
