Penyelesaian

  1. Yudistira (Master) akan digunakan sebagai DNS Master, Werkudara sebagai DNS Slave, Arjuna merupakan Load Balancer yang terdiri dari beberapa Web Server yaitu Prabakusuma, Abimanyu, dan Wisanggeni. Buatlah topologi dengan pembagian sebagai berikut. Folder topologi dapat diakses pada drive berikut

    Untitled

    1. Pandudewanata (Server)

      auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
	address 192.202.1.1
	netmask 255.255.255.0

auto eth2
iface eth2 inet static
	address 192.202.2.1
	netmask 255.255.255.0

auto eth3
iface eth3 inet static
	address 192.202.3.1
	netmask 255.255.255.0

    2. Nakula (Client)

      auto eth0
iface eth0 inet static
	address 192.202.1.2
	netmask 255.255.255.0
	gateway 192.202.1.1

    3. Sadewa (Client)

      auto eth0
iface eth0 inet static
	address 192.202.1.3
	netmask 255.255.255.0
	gateway 192.202.1.1

    4. Yudistira (Master)

      auto eth0
iface eth0 inet static
	address 192.202.1.4
	netmask 255.255.255.0
	gateway 192.202.1.1

    5. Werkudara (Slave)

      auto eth0
iface eth0 inet static
	address 192.202.1.5
	netmask 255.255.255.0
	gateway 192.202.1.1

    6. Arjuna (WebServer)

      auto eth0
iface eth0 inet static
	address 192.202.2.2
	netmask 255.255.255.0
	gateway 192.202.2.1

    7. Prabukusuma (Worker)

      auto eth0
iface eth0 inet static
	address 192.202.3.2
	netmask 255.255.255.0
	gateway 192.202.3.1

    8. Abimanyu (WebServer-Worker)

      auto eth0
iface eth0 inet static
	address 192.202.3.3
	netmask 255.255.255.0
	gateway 192.202.3.1

    9. Wisanggeni (Worker)

      auto eth0
iface eth0 inet static
	address 192.202.3.4
	netmask 255.255.255.0
	gateway 192.202.3.1

    10. meletakkan iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE -s 192.202.0.0/16 pada /root/.bashrc pada Pandudewanata. Terakhir, tambahkan echo 'nameserver 192.168.122.1' > /etc/resolv.conf untuk setiap node pada /root/.bashrc

    • Pada setiap node masukkan bash ini untuk mengetes akses ke internet

      echo '#!/bin/bash
ping -c 5 google.com' > soal1.sh

    • Jalankan Script

      nano /root/.bashrc
./soal1.sh

      Untitled

  2. Buatlah website utama pada node arjuna dengan akses ke arjuna.yyy.com dengan alias www.arjuna.yyy.com dengan yyy merupakan kode kelompok. Server akan diletakkan di Yudhistira sehingga masuk ke node yudhistira

    Jadikan arjuna.d22.com sebagai master

     apt-get update
 apt-get install bind9 -y

    echo 'zone "arjuna.d22.com" {
        type master;
        file "/etc/bind/jarkom/arjuna.d22.com";
};' > /etc/bind/named.conf.local

    Pada "arjuna" buat folder di dalam etc/bind

    mkdir /etc/bind/jarkom

    Copy file db.local dan ganti nama

    cp /etc/bind/db.local /etc/bind/jarkom/arjuna.d22.com

    Buka file /etc/bind/arjuna/arjuna.d22.com dan tuliskan

    echo "
;
; BIND data file for local loopback interface
;
\$TTL    604800
@       IN      SOA     arjuna.d22.com. root.arjuna.d22.com. (
                              2         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      arjuna.d22.com.
@       IN      A       192.202.1.4      ; IP Yudhistira
www     IN      CNAME   arjuna.d22.com.   ; Alias
@       IN      AAAA    ::1
" > /etc/bind/jarkom/arjuna.d22.com

    Lalu restart bind9

    service bind9 restart

    Test di node lain di sini kami menggunakan node Nakula (Client)

    echo "
nameserver 192.202.1.4 # IP yudhistira
" > /etc/resolv.conf

ping arjuna.d22.com -c 3

    Untitled

  3. Dengan cara yang sama seperti soal nomor 2, buatlah website utama dengan akses ke abimanyu.yyy.com dan alias www.abimanyu.yyy.com.

    echo 'zone "arjuna.d22.com" {
        type master;
        file "/etc/bind/jarkom/arjuna.d22.com";
};
zone "abimanyu.d22.com" {
        type master;
        file "/etc/bind/jarkom/abimanyu.d22.com";
};' > /etc/bind/named.conf.local

cp /etc/bind/db.local /etc/bind/jarkom/abimanyu.d22.com

echo "
;
; BIND data file for local loopback interface
;
\$TTL    604800
@       IN      SOA     abimanyu.d22.com. root.abimanyu.d22.com. (
                              3         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      abimanyu.d22.com.
@       IN      A       192.202.1.4      ; IP Yudhistira
www     IN      CNAME   abimanyu.d22.com.  ; Alias
@       IN      AAAA    ::1
" > /etc/bind/jarkom/abimanyu.d22.com

service bind9 restart

    Test di node Nakula (Client)

    echo "
nameserver 192.202.1.4 # IP yudhistira
" > /etc/resolv.conf

ping abimanyu.d22.com -c 3

    Untitled

  4. Kemudian, karena terdapat beberapa web yang harus di-deploy, buatlah subdomain parikesit.abimanyu.d22.com yang diatur DNS-nya di Yudhistira dan mengarah ke Abimanyu.

    cukup menambahkan parikesit

    echo "
;
; BIND data file for local loopback interface
;
\$TTL    604800
@       IN      SOA     abimanyu.d22.com. root.abimanyu.d22.com. (
                              2         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      abimanyu.d22.com.
@       IN      A       192.202.1.4       ; IP yudhistira
www     IN      CNAME   abimanyu.d22.com.   ; Alias
parikesit    IN      A       192.202.3.3
www.parikesit    IN      CNAME   parikesit
@       IN      AAAA    ::1
" > /etc/bind/jarkom/abimanyu.d22.com

service bind9 restart

    Test di node lain

    echo "
nameserver 192.202.1.4 # IP yudhistira
" > /etc/resolv.conf

ping parikesit.abimanyu.d22.com -c 5
ping www.parikesit.abimanyu.d22.com -c 5

    Untitled

  5. Buat juga reverse domain untuk domain utama. (Abimanyu saja yang direverse)

    tambahkan konfigurasi in-addr.arpa pada fiile named.conf.local, seperti berikut :

    echo 'zone "arjuna.d22.com" {
        type master;
        file "/etc/bind/jarkom/arjuna.d22.com";
};
zone "abimanyu.d22.com" {
        type master;
        file "/etc/bind/jarkom/abimanyu.d22.com";
};

zone "1.202.192.in-addr.arpa" {
    type master;
    file "/etc/bind/jarkom/1.202.192.in-addr.arpa";
};' > /etc/bind/named.conf.local

cp /etc/bind/db.local /etc/bind/jarkom/1.202.192.in-addr.arpa

echo "
;
; BIND data file for local loopback interface
;
\$TTL    604800
@       IN      SOA     abimanyu.d22.com. root.abimanyu.d22.com. (
                              5         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
1.202.192.in-addr.arpa.       IN      NS      abimanyu.d22.com.
4 IN PTR abimanyu.d22.com.
" > /etc/bind/jarkom/1.202.192.in-addr.arpa

service bind9 restart

    Testing di node Nakula (Client)

    echo "
nameserver 192.168.122.1 # IP public
" > /etc/resolv.conf

apt-get update
apt-get install dnsutils

echo "
nameserver 192.202.1.4 # IP yudhistira
" > /etc/resolv.conf

host -t PTR 192.202.1.4

    Untitled

  6. Agar dapat tetap dihubungi ketika DNS Server Yudhistira bermasalah, buat juga Werkudara sebagai DNS Slave untuk domain utama.

    • pada Yudistira (Master)

      echo '
zone "arjuna.d22.com" {
        type master;
		notify yes;
		also-notify { 192.202.1.5; }; 
        allow-transfer { 192.202.1.5; }; 
        file "/etc/bind/jarkom/arjuna.d22.com";
};

zone "abimanyu.d22.com" {
        type master;
		notify yes;
		also-notify { 192.202.1.5; }; 
        allow-transfer { 192.202.1.5; }; 
        file "/etc/bind/jarkom/abimanyu.d22.com";
};

zone "1.202.192.in-addr.arpa" {
    type master;
    file "/etc/bind/jarkom/1.202.192.in-addr.arpa";
};
' > /etc/bind/named.conf.local

service bind9 restart

    • pada Werkudara (Slave)

      apt-get update
apt-get install bind9 -y

echo '
zone "arjuna.d22.com" {
    type slave;
    masters { 192.202.1.4; }; 
    file "/var/lib/bind/arjuna.d22.com";
};
zone "abimanyu.d22.com" {
    type slave;
    masters { 192.202.1.4; }; 
    file "/var/lib/bind/abimanyu.d22.com";
};' > /etc/bind/named.conf.local

service bind9 restart

    Test stop pada Yudistira (Master) dan coba di node lain

    service bind9 stop

    Untitled

    Coba akses dari node Nakula (Client)

    echo "
nameserver 192.202.1.4 # IP yudhistira
nameserver 192.202.1.5 # IP werkudara
" > /etc/resolv.conf

ping arjuna.d22.com -c 5
ping abimanyu.d22.com -c 5

    Untitled

  7. Seperti yang kita tahu karena banyak sekali informasi yang harus diterima, buatlah subdomain khusus untuk perang yaitu baratayuda.abimanyu.yyy.com dengan alias www.baratayuda.abimanyu.yyy.com yang didelegasikan dari Yudhistira ke Werkudara dengan IP menuju ke Abimanyu dalam folder Baratayuda.

    • Mengkonfigurasi Nginx untuk load balancing:
      • Buat upstream backend yang berisi daftar server backend: upstream backend { ... }
      • Buat konfigurasi server untuk listen pada port 80 dan server_name arjuna: server { ... }
      • Atur proxy_pass untuk meneruskan permintaan ke backend: proxy_pass <http://backend>;

    Ketika dicoba di masing masing workerlynx localhost maka muncul seperti ini :

    Untitled

    Untitled

    Untitled

  10. Kemudian gunakan algoritma Round Robin untuk Load Balancer pada Arjuna. Gunakan server_name pada soal nomor 1. Untuk melakukan pengecekan akses alamat web tersebut kemudian pastikan worker yang digunakan untuk menangani permintaan akan berganti ganti secara acak. Untuk webserver di masing-masing worker wajib berjalan di port 8001-8003. Contoh

    • Prabakusuma:8001

    • Abimanyu:8002

    • Wisanggeni:8003

    • Pada Arjuna

      apt-get update && apt install nginx php php-fpm -y
apt-get install apache2

service nginx start
service nginx status
php -v

echo "
upstream backend {

Kendala Pengerjaan

  • Pada nomor 14, saya telah melakukan option saat saya melakukan -indexes untuk /secret dan +indexes untuk /public, supaya folder /public hanya dapat melakukan directory listing sedangkan pada folder /secret tidak dapat diakses (403 Forbidden). Namun saat di test, konfigurasi tersebut tidak berjalan dengan baik. Saya telah mencoba2 untuk mengubah konfigurasi tersebut --yang secara syntaxis benar, namun tetap tidak berjalan dengan baik.
