PowerDNS: Instalasi di Ubuntu

Install PowerDNS di Ubuntu

Operating system: Ubuntu 14.04 LTS server
IP Address: 192.168.0.100/24
Hostname: refserver

Update apps

sudo apt-get update
sudo apt-get upgrade -y

Instalasi & Setup MySQL

sudo apt-get install mysql-server mysql-client

Jika sedang belajar dapat menggunakan password root 123456. Untuk operasional sebaiknya jangan menggunakan password root 123456.

Edit /etc/mysql/my.cnf agar MySQL mendengarkan semua interfaces.

sudo vi /etc/mysql/my.cnf

Cari kalimat berikut, dan di beri pagar (#).

[...]
#bind-address           = 127.0.0.1
[...]

Simpan dan tutup file. Restart MySQL service.

sudo service mysql restart

Selesai sudah proses instalasi MySQL. Selanjutnya kita akan menginstalasi PowerDNS.

Install PowerDNS

Instalasi

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

Lakukan:

• Tekan 'Yes' untuk mengkonfigurasi database untuk pdns-backend-mysql dengan dbconfig-common.
• Masukan password root MySQL (dalam contoh ini 123456).
• Masukan password untuk pdns-backend-mysql untuk register ke database server.
• Ulangi masukan password untuk pdns-backend-mysql untuk register ke database server.

Sekarang PowerDNS sudah di instalasi.

Create PowerDNS Database and User in MySQL The next step is we should now create the necessary database, user account, tables, and records etc., for the PowerDNS.

Enter to MySQL prompt using command:

sudo mysql -u root -p

Create database, namely ‘powerdns’. You can define your own.

CREATE DATABASE powerdns;
Create database user, namely ‘poweruser’.

GRANT ALL ON powerdns.* TO 'poweruser '@'localhost' IDENTIFIED BY 'ubuntu';

Here,

powerdns – is the database;

poweruser – is the database user,

ubuntu – is the password for the ‘poweruser’ user.

I recommend you to use any strong password to tighten the security.

Enter the following command to update the user settings.

FLUSH PRIVILEGES;

Now, use the powerdns database with command:

USE powerdns;

Create the necessary tables and records.

First, let us create domains table:

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 for domains table:

CREATE UNIQUE INDEX name_index ON domains(name);

Create records table:

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 the following indexes for records table:

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 the supermasters table:

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

Finally, exit from MySQL prompt using command:

quit;

Configure PowerDNS Now, we should configure PowerDNS to use MySQL as backend to store Zone files and records.

Remove the existing PowerDNS configuration files.

sudo rm /etc/powerdns/pdns.d/*.*

Then, create file /etc/powerdns/pdns.d/pdns.local.gmysql.conf file;

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

Add the following lines. Set the correct database name and database user which we created earlier.

# MySQL Configuration
#
# Launch gmysql backend
launch=gmysql

# gmysql parameters
gmysql-host=localhost
gmysql-dbname=powerdns
gmysql-user=poweruser
gmysql-password=ubuntu

Finally restart powerdns service.

sudo service pdns restart

Test PowerDNS

First, edit /ect/resolv.conf file,

sudo vi /etc/resolv.conf

Set the name server IP address:

auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.250
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.250
dns-search home

We completed all installation and configuration parts. Now, we will check whether PowerDNS is really working or not.

First check if PowerDNS is listening:

sudo netstat -tap | grep pdns

Sample output:

tcp        0      0 *:domain                *:*                     LISTEN      1549/pdns_server-in

Now, enter the following command to check PowerDNS is working:

sudo dig @127.0.0.1

Or,

sudo dig @localhost

Sample output:

; <<>> DiG 9.9.5-3-Ubuntu <<>> @127.0.0.1
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 65075
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:

;; WHEN: Mon Mar 30 14:38:58 IST 2015
;; MSG SIZE  rcvd: 29

Or,

sudo dig @192.168.1.250

Where, 192.168.1.250 is my PowerDNS server’s IP address.

Sample output:

; <<>> DiG 9.9.5-3-Ubuntu <<>> @192.168.1.250
; (1 server found)
;; global options: +cmd
;; Got answer:

;; WHEN: Mon Mar 30 14:39:49 IST 2015
;; MSG SIZE  rcvd: 29

That’s it. PowerDNS is ready to use.

I have successfully installed and configured PowerDNS, now what? It is time to manage PowerDNS using Poweradmin administration tool.
