Installing PowerDNS With MySQL On CentOS

What is PowerDNS?
PowerDNS is a MySQL-based DNS server, written in C++ and licensed under the GPL. PowerDNS can be managed through a web interface (PowerAdmin). This guide shows how to install it on CentOS.

1. Installing MySQL
[root@server ~]# yum -y install mysql mysql-server

2. Create system startup links for MySQL
[root@server ~]# chkconfig --levels 235 mysqld on
[root@server ~]# service mysqld start

3. Check if MySQL is running
[root@server ~]# netstat -tap grep mysql
tcp 0 0 *:mysql *:* LISTEN 28179/mysqld

4. Set password for user root
[root@server ~]# mysqladmin -u root password password123

5. Install PowerDNS
[root@server ~]# yum -y install pdns pdns-backend-mysql

6. Setting database
[root@server ~]# mysql -u root -p
mysql> CREATE DATABASE powerdns;
mysql> user powerdns;
mysql> CREATE TABLE domains (
-> id INT auto_increment,
-> name VARCHAR(255) NOT NULL,
-> master VARCHAR(128) DEFAULT NULL,
-> last_check INT DEFAULT NULL,
-> type VARCHAR(6) NOT NULL,
-> notified_serial INT DEFAULT NULL,
-> account VARCHAR(40) DEFAULT NULL,
-> primary key (id)
-> );

mysql> CREATE UNIQUE INDEX name_index ON domains(name);
mysql> CREATE TABLE records (
-> id INT auto_increment,
-> domain_id INT DEFAULT NULL,
-> name VARCHAR(255) DEFAULT NULL,
-> type VARCHAR(6) DEFAULT NULL,
-> content VARCHAR(255) DEFAULT NULL,
-> ttl INT DEFAULT NULL,
-> prio INT DEFAULT NULL,
-> change_date INT DEFAULT NULL,
-> primary key(id)
-> );

mysql> CREATE INDEX rec_name_index ON records(name);
mysql> CREATE INDEX nametype_index ON records(name,type);
mysql> CREATE INDEX domain_id ON records(domain_id);

mysql> CREATE TABLE supermasters (
-> ip VARCHAR(25) NOT NULL,
-> nameserver VARCHAR(255) NOT NULL,
-> account VARCHAR(40) DEFAULT NULL
-> );

mysql> quit;
[root@server ~]# nano /etc/pdns/pdns.conf

[root@server ~]# service pdns start

8. Preparing the system for PowerAdmin installation
[root@server ~]# yum -y install httpd php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mhash gettext

9. Create system startup links for apache and start it
[root@server ~]# chkconfig --levels 235 httpd on
[root@server ~]# service httpd start

10. Install following two PEAR packages
yum -y install php-pear-DB php-pear-MDB2-Driver-mysql

[root@server ~]# wget https://www.poweradmin.org/download/poweradmin-2.1.2.tgz
[root@server ~]# tar zxvf poweradmin-2.1.2.tgz -C /var/www/html/
[root@server ~]# mv poweradmin-2.1.2 poweradmin
