Master-Slave-DNS-with-PowerDNS

Repository ini berisikan instalasi dan konfigurasi Master-Slave DNS pada PowerDNS

Task

Instalasi dan Konfigurasi

  • PowerDNS
  • Database Server MariaDB 10.1.44
  • Glue Record Domain

Ketentuan pengerjaan:

  • Menggunakan 2 VPS dengan OS centos7
  • Menggunakan domain utama (domain.tld)
  • Menggunakan DNS Server Pdns
  • Menggunakan Master Slave Pdns
  • Menggunakan Database Server MariaDB 10.1.44

Instalasi dan Konfigurasi Pdns dan MariaDB 10.1.44 (Master)

Step 1: Install MariaDB 10.1.44

Untuk melakukan instalasi MariaDB 10.1.44 yang pertama adalah melakukan remote ke IP VPS dengan menggunakan SSH

$ ssh root@ipaddress

Setelah berhasil login ke VPS, lakukan pembaharuan paket/repository dari system operasi Centos7 dengan perintah sebagai berikut:

# yum -y update

Setelah melakukan update system selanjutnya lakukan install epel-release

# yum install epel-release -y

Setelah melakukan install epel-release selanjutnya lakukan instalasi database server mariaDB 10.1.44 dan langkah pertama ialah menambahkan repository untuk mariaDB.

# vi /etc/yum.repos.d/mariadb.repo

Masukan perintah berikut:

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Setelah menambahkan repo mariaDB, lakukan instalasi mariaDB dengan perintah berikut:

# yum install mariadb-server

Selanjutnya lakukan enable direktori dan file database mariaDB, berikut perintahnya:

# systemctl enable mariadb

Setelah direktori dan file database mariaDB dienable, jalankan service mariaDB dengan perintah berikut:

# systemctl start mariadb

Apabila paket database server telah selesai diinstall pastikan service mariaDB berjalan dengan status Running.

# systemctl status mariadb

           └─29897 /usr/sbin/mysqld

Step 2: Secure mariaDB server and Configure Database

Setelah melakukan instalasi mariaDB Server selanjutnya kita harus mengamankan databese server dengan cara menambahkan password login saat mengakses mariaDB server.

# mysql_secure_installation

Nantinya kita akan melakukan perubahan password untuk root database server, pilih Y dan masukan Password baru yang kuat.

Set root password? [Y/n] Y
New password: 
Re-enter new password:

Apabila ada yang lain silakan klik Y

Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

Setelah itu kita coba untuk melakukan login dengan password baru yang telah dibuat dengan perintah berikut:

# mysql -u root -p
Input Password

Apabila telah login selanjutnya buat database, user dan password untuk service PowerDNS.

MariaDB [(none)]> Create database testpdns;
MariaDB [(none)]> grant all privileges on testdns.* to pdns@localhost identified by 'pdnspassword';
MariaDB [(none)]> flush privileges;

Setelah itu pilih database testpdns;

MariaDB [(none)]>use testpdns;
MariaDB [testpdns]>

Buat table baru untuk menyimpan record pdns pada database testpdns.

MariaDB [testpdns]> CREATE TABLE domains (
  id                    INT AUTO_INCREMENT,
  name                  VARCHAR(255) NOT NULL,

MariaDB [testpdns]> CREATE INDEX comments_name_type_idx ON comments (name, type);
MariaDB [testpdns]> CREATE INDEX comments_order_idx ON comments (domain_id, modified_at);
MariaDB [testpdns]> CREATE TABLE domainmetadata (

MariaDB [testpdns]> CREATE INDEX domainmetadata_idx ON domainmetadata (domain_id, kind);
MariaDB [testpdns]> CREATE TABLE cryptokeys (

Konfigurasi Zona dan Add Record DNS di PowerDNS Master

Langkah pertama terlebih dahulu kita buat zona untuk menyimpan record domain.

MariaDB [testpdns]> INSERT INTO domains (name, type) values ('padiakse.my.id', 'Master');

Langkah kedua tambahkan record domain pada table records

MariaDB [testpdns]> INSERT INTO records (domain_id, name, content, type,ttl,prio) VALUES (1,'padiakse.my.id','padiakse.my.id root.padiakse.my.id 1 10380 3600 604800 3600','SOA',86400,NULL);
MariaDB [testpdns]> INSERT INTO records (domain_id, name, content, type,ttl,prio) VALUES (1,'padiakse.my.id','pd1.padiakse.my.id','NS',86400,NULL);
MariaDB [testpdns]> INSERT INTO records (domain_id, name, content, type,ttl,prio) VALUES (1,'padiakse.my.id','pd2.padiakse.my.id','NS',86400,NULL);
MariaDB [testpdns]> INSERT INTO records (domain_id, name, content, type,ttl,prio) VALUES (1,'pd1.padiakse.my.id','103.23.20.70','A',3600,NULL);
MariaDB [testpdns]> INSERT INTO records (domain_id, name, content, type,ttl,prio) VALUES (1,'pd2.padiakse.my.id','117.53.47.189','A',3600,NULL);
MariaDB [testpdns]> INSERT INTO records (domain_id, name, content, type,ttl,prio) VALUES (1,'padiakse.my.id','103.23.20.70','A',3600,NULL);

Langkah ketiga tambahkan kolom change_date pada table records

MariaDB [testpdns]> ALTER TABLE records add change_date INT DEFAULT NULL;

Berikut hasil penambahan record tersebut.

MariaDB [testpdns]> select *from records;
+----+-----------+------------------------+------+----------------------------------------------------------------+-------+------+----------+-----------+------+-------------+
| id | domain_id | name                   | type | content                                                        | ttl   | prio | disabled | ordername | auth | change_date |

Konfigurasi Table di PowerDNS Slave

Langkah pertama tambahkan data berikut pada table supermasters

MariaDB [Slave_pdns]> insert into supermasters values ('103.23.20.70', 'pd2.padiakse.my.id', 'admin');
MariaDB [Slave_pdns]> select *from supermasters;
+--------------+--------------------+---------+
| ip           | nameserver         | account |
+--------------+--------------------+---------+

Apabila dengan tools dig belum muncul untuk record tersebut kemungkinan besar record tersebut masih dalam proses Propagasi atau kita salah memaasukan record tersebut untuk itu kita dapat mengecek kembali pada table record dan apabila tidak ada masalah pada table record kita dapat melakukan pengecekan proses propagasi record domain dan berikut kami lampirkan:

Berikut dokumentasi dari report record DNS yang telah ditambahkan tadi.
