  • CentOS 7 x86_64

CentOS 6 x86_64:

1. Enable epel repository using the instruction from here: http://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F

2. Install PowerDNS and MySQL

yum -y install mysql mysql-server pdns pdns-backend-mysql
chkconfig --levels 235 mysqld on
chkconfig --levels 235 pdns on
service mysqld start

3. Set a MySQL root password

mysqladmin -u root password MYNEWPASSWORD

4. Download the PowerDNS SQL and import it

wget http://files.soluslabs.com/solusvm/pdns/pdns.sql
mysql --user=root --password=MYNEWPASSWORD < pdns.sql

5. Edit /etc/pdns/pdns.conf with your database details:

launch=gmysql
gmysql-host=127.0.0.1
gmysql-user=root
gmysql-password=MYNEWPASSWORD
gmysql-dbname=powerdns

6. To give permission for the MySQL user to connect from your SolusVM master, use following:

mysql -u root -p

After entering the password use following:

GRANT ALL ON powerdns.* TO 'root'@'YOUR_SOLUSVM_MASTERS_IP' IDENTIFIED BY 'MYNEWPASSWORD';
FLUSH PRIVILEGES;

7. Start PowerDNS:

/etc/init.d/pdns start

To do a monitored start, use following:

/etc/init.d/pdns monitor

CentOS 7 x86_64:

1. Enable epel repository using the instruction from here: http://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F

2. Install PowerDNS and MySQL

yum -y install mariadb mariadb-server pdns pdns-backend-mysql
systemctl enable mariadb
systemctl enable pdns
systemctl start mariadb

3. Set a MySQL root password

mysqladmin -u root password MYNEWPASSWORD

4. On CentOS 7 pdns 4.0.6 is installed by default and in this version powerdns database is different from the one in version 3.X.
