PowerDNS: Instalasi Server & Recursor di satu mesin

From OnnoWiki
Jump to navigation Jump to search

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;

USE powerdns;

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
loglevel=6

recursor=127.0.0.1:53

Edit /etc/powerdns/recursor.conf

vi /etc/powerdns/recursor.conf

allow-from=127.0.0.1
dont-query=
local-address=127.0.0.1

setuid=pdns


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:

  1. 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 ;-)
