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 Configure database for pdns-backend-mysql with dbconfig-common?
• Masukan password root MySQL (dalam contoh ini 123456).
• Masukan password untuk pdns-backend-mysql untuk register ke database server. Untuk memudahkan gunakan password 123456
• Ulangi masukan password untuk pdns-backend-mysql untuk register ke database server.

Sekarang PowerDNS sudah di instalasi.

Create PowerDNS Database dan User di MySQL

Masuk ke MySQL

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
;; WARNING: recursion requested but not available

;; 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.
