View source for PowerDNS: Instalasi Master dan Slave sekaligus jadi satu

Dalam tutorial ini akan di coba untuk mengkonfigurasi powerdns agar bisa berjalan sebagai master dan slave di satu mesin.

Disini akan digunakan 

* IP address 192.168.0.100 (powerdns server)
* IP address 127.0.01 (recursor)



==Instalasi powerdns==

 apt-get install pdns-server pdns-backend-mysql pdns-recursor mysql-server

Akan ada error / warning karena pdns-server dan pdns-recursor sebetulnya tidak bisa jalan di satu mesin. Kita akan mengakali dari sisi konfigurasi.

==Konfigurasi Database==

Set password 'poweruser' untuk akses ke database powerdns.
Buat semua tabel & index yang dibutuhkan.

 mysql -u root -p123456

Lakukan

 CREATE DATABASE powerdns;
 GRANT ALL ON powerdns.* TO 'poweruser'@'localhost' IDENTIFIED BY 'ubuntu';
 
 FLUSH PRIVILEGES;

==Konfigurasi powerdns==

3.Powerdns configuration

Edit /etc/powerdns/pdns.d/pdns.local.gmysql.conf

 sudo vi /etc/powerdns/pdns.d/pdns.local.gmysql.conf

isi

 # MySQL Configuration
 #
 # Launch gmysql backend
 launch=gmysql
 
 # gmysql parameters
 gmysql-host=localhost
 gmysql-port=
 gmysql-dbname=powerdns
 gmysql-user=poweruser
 gmysql-password=ubuntu
 gmysql-dnssec=yes
 # gmysql-socket=

Edit /etc/powerdns/pdns.conf 

 vi /etc/powerdns/pdns.conf 

isi

 allow-recursion=0.0.0.0/0
 config-dir=/etc/powerdns
 daemon=yes
 guardian=yes
 include-dir=/etc/powerdns/pdns.d
 launch=
 setgid=pdns
 setuid=pdns
 version-string=powerdns
 local-address=192.168.0.100
 local-port=53
 
 log-dns-details=yes
 log-dns-queries=yes
 logging-facility=0

==Restart==

 /etc/init.d/pdns restart
 /etc/init.d/pdns-recursor restart










Poweradmin installation

Poweradmin will be installed on powerdns master host, so we need to install necessary packages:

 apt-get install apache2-mpm-prefork php5-mysql libapache2-mod-php5 php-pear php-mdb2 php-mdb2-driver-mysql

Then download, unpack and make some preparations before installation process:

 cd /var/www
 wget --no-check-certificate https://www.poweradmin.org/download/poweradmin-2.1.4.tgz
 tar zxvf poweradmin-2.1.4.tgz 
 ln -s poweradmin-2.1.4 poweradmin
 chown www-data.www-data -R poweradmin-2.1.4
 cp /var/www/poweradmin/inc/config-me.inc.php /var/www/poweradmin/inc/config.inc.php

With default apache2 configuration, type in web browser address http://192.168.56.3/poweradmin/install and follow steps to finish poweradmin installation

Instead of what is shown in step 6 use below listed grant for user poweradmin:

 GRANT SELECT, INSERT, UPDATE, DELETE ON powerdns.* TO 'poweradmin'@'localhost';
 FLUSH PRIVILEGES;

After successful installation remove install directory.

 rm -rf /var/www/poweradmin/install

There is a small bug in latest stable release of poweradmin-2.1.4, which has been explained in ticket https://www.poweradmin.org/trac/ticket/346.To repair that replace line 196 with $retcount++; in inc/templates.inc.php file.

Poweradmin usage

Type in your web browser http://192.168.56.3/poweradmin and login as admin with password you typed in installation (step 3)

Easiest way to manage domains is to create zone template or templeates. Got to List zone templates > Add zone template > fill Name('default' in that case)

Then edit 'default' zone template by adding new records:

 #examples
 [ZONE] SOA ns1.example.com hostmaster.example.com [SERIAL] 10800 3600 604800 600
 [ZONE] A   192.168.56.3 86400
 www.[ZONE] A   192.168.56.3 86400
 mail.[ZONE] A   192.168.56.3 86400
 [ZONE] NS  ns1.example.com 86400
 [ZONE] NS  ns2.example.com 86400
 [ZONE] MX  mail.[ZONE] 10 86400

Make some tests with adding new domain using created zone template by adding master zone (choose type: master)

Don't forget to add ns1.example.com and ns2.example.com A type records.

Finally add into slave mysql server direction where master powerdns server is located by adding proper ip and master ns domain name.

use powerdns;
 insert into supermasters values ('192.168.56.3', 'ns1.example.com', 'admin');

Migration from bind

Use zone2sql script to migrate domains from bind to powerdns

 zone2sql  --gmysql --named-conf=/etc/bind/named.conf > bind.sql

If domain type is NATIVE, change it into MASTER using example sed command

 sed 's/NATIVE/MASTER/g' bind.sql > bind.master.sql

Thats all folks. If you have any questions don't hesitate to write ;-)
