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

```
 
#### 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.
 
> ```

Lakukan konfigurasi file `pdns.conf`
 
> ```
# cd /etc/pdns/
pdns#  vi pdns.conf

## Konfigurasi PowerDNS Master Slave
#### Step 1: Konfigurasi PowerDNS Master
 
Lakukan konfigurasi file `pdns.conf`
 
> ```
# cd /etc/pdns/
pdns#  vi pdns.conf
```
 
Lakukan perubahan pada file  pdns.conf seperti berikut:
 
* Script ini digunakan untuk mengenali alamat IP dari PowerDNS Slave
 
> ```
#################################
# allow-axfr-ips        Allow zonetransfers only to these subnets
#
# allow-axfr-ips=127.0.0.0/8,::1
allow-axfr-ips=117.53.47.189 (isikan alamat IP Pdns Slave)
```
 
* Script ini digunakan untuk menandai bahwa PowerDNS pada VM ini berperan sebagai master
 
> ```
#################################
# master        Act as a master
#
# master=no
master=yes
```
 
#### Step 2: Konfigurasi PowerDNS Slave
Lakukan konfigurasi file `pdns.conf`
 
> ```
# cd /etc/pdns/
pdns#  vi pdns.conf
```
 
Lakukan perubahan pada file  pdns.conf seperti berikut:
 
* Script ini digunakan untuk mengenali alamat IP dari PowerDNS Master
 
> ```
#################################
# allow-axfr-ips        Allow zonetransfers only to these subnets
#
# allow-axfr-ips=127.0.0.0/8,::1
allow-axfr-ips=103.23.20.70 (Isikan IP Pdns Master)
```
 
* Script ini digunakan untuk mengizinkan alamat IP master agar dapat melakukan perubahan pada PowerDNS Slave
 
> ```
#################################
# allow-dnsupdate-from  A global setting to allow DNS updates from these IP ranges.
#
# allow-dnsupdate-from=127.0.0.0/8,::1
allow-dnsupdate-from=103.23.20.70 (Isikan IP Pdns Master)
```
 
* Script ini digunakan untuk mengizinkan alamat IP master agar bisa memberi info terkait dengan perubahan pada PowerDNS Master ke PowerDNS Slave
 
> ```
#################################
# allow-notify-from     Allow AXFR NOTIFY from these IP ranges. If empty, drop all incoming notifies.
#
# allow-notify-from=0.0.0.0/0,::/0
allow-notify-from=103.23.20.70 (Isikan IP Pdns Master)
```
 
* Script ini digunakan sebagai identitas PowerDNS Slave
 
> ```
#################################
# slave Act as a slave
#
# slave=no
slave=yes
```
 
* Script ini dijalankan untuk melakukan refresh pada PowerDNS Slave dengan interval waktu tertentu
 
> ```
#################################
# slave-cycle-interval  Schedule slave freshness checks once every .. seconds
#
# slave-cycle-interval=60
slave-cycle-interval=60
```
 
## 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;
