http://gnudip2.sourceforge.net

Here we provide a dynamic DNS service using PowerDNS and MySQL.

Here we install the packages and set the MySQL root password. Adjust as necessary:

yum install pdns pdns-backend-mysql mysql-server vim-enhanced

chkconfig mysqld on
chkconfig pdns on
service mysqld start
mysqladmin -u root password 'new-password'
mysqladmin -u root -h [your-server-fqdn] password 'new-password'

Now we log in to MySQL:

mysql -u root -p

Now, at the MySQL prompt, we configure MySQL permissions. Adjust as necessary:

CREATE DATABASE powerdns;

GRANT ALL ON powerdns.* TO 'power_admin'@'localhost' IDENTIFIED BY 'power_admin_password';
GRANT ALL ON powerdns.* TO 'power_admin'@'[your-server-fqdn]' IDENTIFIED BY 'power_admin_password';
FLUSH PRIVILEGES;

Now we create the database:

USE powerdns;

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)
);

CREATE UNIQUE INDEX name_index ON domains(name);

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)
);

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

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

quit;

vim /etc/pdns/pdns.conf

Add the following lines to 'Launch' section of pdns.conf:

#################################
# launch        Which backends to launch and order to query them in
#
# launch=
launch=gmysql
gmysql-host=127.0.0.1
gmysql-user=power_admin
gmysql-password=power_admin_password
gmysql-dbname=powerdns

Start PowerDNS:

service pdns start
