3. Installation MariaDB.

3.1 Installation.

Mariadb update added to the repositories.
curl -LsS https://r.mariadb.com/downloads/mariadb_repo_setup | bash
dnf update
dnf install MariaDB-server
systemctl enable --now mariadb

It is the version MariaDB 11.6.2.
The mysql command is replaced by mariadb.
If you want to use the MySQL command, you must install MariaDB-client-compat.

Secure MariaDB.
Example for root password: XTG56AB50!
mariadb-secure-installation

Enter current password for root (enter for none):  
OK, successfully used password, moving on...  
Switch to unix_socket authentication [Y/n] n  
Change the root password? [Y/n] y  
New password:XTG56AB50!  
Remove anonymous users? [Y/n] y  
Disallow root login remotely? [Y/n] y  
Remove test database and access to it? [Y/n] y  
Reload privilege tables now? [Y/n] y  
 ... Success!

3.2 Create powerdns database.

Example: create the powerdns database and adminpdns@locahost password: 641fqAB4d
mariadb -u root -e "create database powerdns;"

mariadb -u root -e "CREATE USER 'adminpdns'@'localhost' IDENTIFIED BY '641fqAB4d';"

mariadb -u root -e "grant all privileges on *.* to adminpdns@localhost;"

mariadb -u root -e "flush privileges;"

3.4 Populate the powerdns database.

It is for version pdns 4.7. and more.
The tables have changed.
Be careful if you had pdns 4.6 for one upgrade to 4.7.

Connect to mariadb as a user with sufficient privileges and issue the following commands.
mariadb -u root -p
use powerdns ;
Copy and paste.
Be careful if there is an error you will have to start all over again.

Connect pdns to the powerdns database.

vi /etc/pdns/pdns.conf
Add to end of file.

launch=gmysql  
#gmysql parameters    
gmysql-host=127.0.0.1  
gmysql-port=3306  
gmysql-dbname=powerdns  
gmysql-user=adminpdns  
gmysql-password=641fqAB4d

We now have a database and an empty table.
PowerDNS should now be able to launch in monitor mode and
display no errors.

Stopping the pdns service.
systemctl stop pdns
Start in monitor mode.
/usr/sbin/pdns_server --daemon=no --guardian=no --loglevel=9

gmysql Connection successful. Connected to database 'powerdns' on '127.0.0.1'

"Normal" start pdns.
systemctl start pdns

3.5 MariadB backup.

Save the powerdns database.
mariadb-dump -u root -p powerdns > backup_powerdns.sql
Restore the powerdns database.
mariadb -u root -p powerdns < backup_powerdns.sql
