Cara Menginstal dan Konfigurasi Lusca sebagai Proxy Server di Ubuntu Server 12.04

 

server proxy adalah server yang (sistem komputer atau aplikasi) yang bertindak sebagai perantara permintaan dari klien mencari sumber daya dari server lain. Seorang klien terhubung ke server proxy, meminta beberapa layanan, seperti file, koneksi, halaman web, atau sumber daya lain yang tersedia dari server yang berbeda dan server proxy mengevaluasi permintaan sebagai cara untuk menyederhanakan dan mengontrol kompleksitasnya. Proxy diciptakan untuk menambah struktur dan enkapsulasi untuk sistem terdistribusi. Saat ini, kebanyakan proxy adalah proxy web, memfasilitasi akses ke konten di World Wide Web dan menyediakan anonimitas.

Manfaat Proxy Server

Secara umum manfaat proxy server ada dua macam, yaitu sebagai berikut:

1. Meningkatkan kinerja jaringan

Dengan kemampuan server proxy untuk menyimpan data permintaan dari aplikasi client, permintaan yang sama dengan permintaan sebelumnya hanya akan diambilkan dari simpanan server proxy. Jika seorang pengguna internet sudah pernah membuka situs yang sama, tidak perlu dihubungkan langsung pada situs sumbernya, tetapi cukup diambilkan dari simpanan server proxy. Dengan cara demikian, koneksi langsung pada server sumbernya dapat dikurangi. Dengan demikian, penggunaan bandwidth internet untuk koneksi langsung menjadi berkurang.

2. Filter permintaan

Server proxy juga dapat digunakan sebagai filter terhadap permintaan data dari suatu situs. Dalam hal ini, server proxy menjadi filter terhadap situs yang boleh atau tidak boleh dikunjungi. Selain itu, server proxy juga dapat sebagai filter terhadap aplikasi client yang dapat menggunakan akses terhadap internet. Dalam hal ini server proxy berlaku sebagai filter terhadap gangguan internet.

Fungsi Proxy Server

Proxy Server meupakan pihak ketiga yang menjadi perantara antara kedua pihak yang saling berhubungan, dalam hal ini adalah jaringan lokal dan jaringan internet. Secara prinsip pihak pertama dan pihak kedua tidak langsung berhubungan, akan tetapi masing-masing berhubungan degan pihak ketiga yaitu proxy.

Tiga fungsi utama proxy server adalah:

1. Connection sharing

Bertindak sebagai gateway yang menjadi batas antara jaringan lokal dan jaringan luar. Gateway juga bertindak sebagai titik dimana sejumlah koneksi dari pengguna lokal akan terhubung kepadanya dan koneksi jaringan luar juga terhubung kepadanya. Dengan demikian koneksi dari jaringan lokal ke internet akan menggunakan sambungan yang dimiliki oleh gateway secara bersama-sama (connecion sharing).

2. Filtering

Bekerja pada layar aplikasi sehingga berfungsi sebagai Firewalll paket filtering yang digunakan untuk melindungi jaringan lokal terhadap gangguan atau serangan dari jaringan luar. Dapat dikonfigurasi untuk menolak situs web tertenu pada waktu-waktu tertentu.

3. Caching

Proxy Server memiliki mekanisme penyimpanan obyek-obyek yang sudah diminta dari server-server di internet. Mekanisme caching akan menyimpan obyek-obyek yang merupakan permintaan dari para pengguna yang di dapat dari iternet.

Keuntungan Proxy Server

Keuntungan proxy server dalam suatu jaringan TCP/IP adalah:
  1. Keamanan jaringan lebih terjaga, karena adanya proxy sebagai pembatas antara jaringan lokal dan jaringan luar (internet)
  2. Pengaksesan kembali terhadap situs-situs yang telah diakses sebelumnya menjadi lebih cepat, karena pengaksesan tidak perlu ke jaringan luar (internet) melainkan ada pada direktori cache proxy.
  3. Terdapat fasilitas filtering, baik filtering pengguna, content dan waktu akses.

Kekurangan Proxy Server

Kekurangan proxy server dalam suatu jaringan TCP/IP adalah:
  1. Pengaksesan terhadap situs yang belum pernah dibuka sebelumnya akan menjadi lebih lambat, karena client harus meminta terlebih dahulu ke pada proxy, setelah itu baru proxy yang akan meminta request dari client tersebut ke pada penyedia layanan internet.
  2. Bila proxy server terlambat melakukan update cache, maka client akan mendapatkan content yang belum update ketika melakukan request content tersebut.

 1. Kita install dulu server nya menggunakan OS ubuntu 12.04 server

Tutorialnya install nya bisa baca di sini

Yang beda cuma partisi nya menggunakan manual

karena server akan digunakan sebagai proxy

2. Partisinya menggunakan manual saja.



 3. Kemudian partisinya di isi dibawah ini , penting partisi dibawah ini disesuaikan dengan ukuran hardisk pc anda kalau yang menggunakan partisi dibawah ini ukuran hardisk nya - + 240-250 GB.

Type Size Location FileSystem Mount
Primary 30 GB Beginning ext4 /
Primary 500 MB Beginning ext4 /boot
Primary 8192 MB Beginning swap swap
Logical 25 GB End btrfs /cache-1
Logical 25 GB End btrfs /cache-2
Logical 25 GB End btrfs /cache-3
Logical 25 GB End btrfs /cache-4
Logical 25 GB End btrfs /cache-5
Logical 46 GB End ext4 /home
Logical 5 GB End ext4 /opt
Logical 5 GB End ext4 /srv
Logical 5 GB End ext4 /tmp
Logical 5 GB End ext4 /usr
Logical 5 GB End ext4 /usr/local

4. Hal hal yang harus dilakukan setelah install ubuntu server 12.04

kita bisa melakukan configurasi dengan cara diremote servernya syaratnya satu jaringan , remote nya menggunakan ssh, caranya:

ssh proxy[hostname computer]@ip server anda masukan sandi server anda
lalu enter anda sudah masuk ke system nya server ,Misal
ssh proxy@192.168.12.38
untuk ubuntu 12.04 server kalau login belum masuk root, anda harus masuk root dulu
sudo su
masukan password server

#hostname dan hostname -f nya harus sama

cara ngecek nya
hostname
proxy
hostname -f
proxy

 # arahkan repository

nano /etc/apt/sources.list
Misalnya saya arah kan repository nya ke kambing :

deb http://kambing.ui.ac.id/ubuntu/ precise main restricted
deb-src http://kambing.ui.ac.id/ubuntu/ precise main restricted

deb http://kambing.ui.ac.id/ubuntu/ precise universe
deb-src http://kambing.ui.ac.id/ubuntu/ precise universe

deb http://kambing.ui.ac.id/ubuntu/ precise multiverse
deb-src http://kambing.ui.ac.id/ubuntu/ precise multiverse
deb http://security.ubuntu.com/ubuntu precise-security main restricted
deb-src http://security.ubuntu.com/ubuntu precise-security main restricted
deb http://security.ubuntu.com/ubuntu precise-security universe
deb-src http://security.ubuntu.com/ubuntu precise-security universe
 # update dan upgrade
untuk ubuntu server kita login belum masuk root
anda masuk dulu sebagai root
apt-get update && dist-upgrade -y
langkah ini akan memakan waktu lama karena akan mendownload dan memasang paket paket yang dibutuhkan pc anda, waktu nya tergantung dengan kecepatan bandwite anda.

5. kita install paket lusca untuk konfigurasi proxynya
 apt-get install lusca squidclient squid-cgi ccze
6. Pindah konfigurasi awal lusca
mv /etc/lusca/squid.conf /etc/lusca/squid.conf.original
7. Buat configurasi  lusca baru
touch /etc/lusca/squid.conf
nano /etc/lusca/squid.conf

#=============================================

# Edit perintah yang bercetak tebal diatas sesuai kebutuhan anda



dns_nameservers 192.168.4.1 127.0.0.1 221.132.112.8

Misalnya diedit seperti dibawah ini :



 dns_nameservers 192.168.40.1 127.0.0.1 8.8.8.8

Maksud nya : # 192.168.40.1 : gateway mikrotix

                     # 127.0.0.1 : localhost

                      #8.8.8.8 : dns google



# Edit localnet alamat ip yang bisa dibaca oleh proxy.



acl localnet src 192.168.40.0/24

Maksudnya : # /24 berarti Jumlah Ip nya 254

                     # syaratnya harus satu subnet dengan dns nameserver tadi.





8. Beri hak akses pada configura squid.conf



chown proxy:proxy /etc/lusca/squid.conf 

9. Buat konfigurasi storeurl.pl



mkdir /etc/squid/ 



touch /etc/squid/storeurl.pl 



nano /etc/squid/storeurl.pl
