How to Setup PowerDNS PowerAdmin Web GUI


In this article i will show how to install PowerDNS PowerAdmin Web GUI. First I will show how to install PowerDNS on CentOS. Our PowerDNS setup will use MySQL database in backend.

PowerDNS is a DNS server able serving very large query volumes and as very performance. Other advantage – PowerDNS is able give us lot of statistics (Log Messages, Queries for records,Remote server IP addresses, hosts sending corrupt packets).

After PowerDNS setup we will configure PowerAdmin Web GUI. Poweradmin is a friendly web based DNS administration tool PowerDNS server. The interface has full support for most of the features of PowerDNS. It has full support for all zone types (master, native and slave), for supermasters for automatic provisioning of slave zones, full support for IPv6 and comes with multi-language support. See feature list for all features.



PowerDNS setup

Install EPEL and REMI repositories:

rpm -ivh
rpm -ivh


Install php, mysql, pdns packages:

yum -y install php php-mcrypt php-pdo php-mysql pdns pdns-backend-mysql mysql-server httpd


Start httpd, mysqld, pdns services and add to autostart:

/etc/init.d/httpd start
/etc/init.d/mysqld start
/etc/init.d/pdns start
chkconfig httpd on
chkconfig mysqld on
chkconfig pdns on


PowerDNS MySQL backend

Create MySQL database ‘powerdns‘:

mysqladmin create powerdns -p

Create user ‘powerdns‘ and grant all ‘privileges‘ on ‘powerdns‘:

mysql -Bse "create user 'powerdns'@'localhost' identified by 'password'" -p
mysql -Bse "grant all privileges on powerdns.* to 'powerdns'@'localhost'" -p


Start MySql console:

# mysql -p
mysql> use powerdns;
