Squid Lusca on Ubuntu

Lusca bertujuan untuk memperbaiki kekurangan dalam Squid-2. Ini juga mendukung berbagai protokol clustering. Menggunakan lusca, sobat bisa menyimpan beberapa isi yang dinamis yang sebelumnya tidak dapat lakukan dengan squid, seperti :

  1. Video Cachingi.e Youtube / tube etc . . .
  2. Windows Update / Linux Updates / Anti-virus , Anti-Malware i.e. Avira/ Avast / MBAM etc . . .
  3. Download caching mp3’s/mpeg/avi etc . .

Di sebagian dunia, bandwidth sangat mahal, oleh karena itu (dalam beberapa skenario) sangat berguna untuk Cache video Youtube atau flash video lainnya, sehingga jika salah satu dari pengguna download video / file flash, mengapa lagi pengguna yang sama atau lainnya tidak dapat men-download file yang sama dari CACHE, mengapa ia harus internet untuk konten yang sama lagi n lagi?

Untuk keperluan ini yang perlu disiapkan sebagai berikut :

  • 1 PC terinstall Ubuntu 14.04 LTS dan sudah dilakukan upgrade paket.

Langkah-Langkah sebagai berikut :

#mkdir /temp
#cd /temp
#touch lusca_install.sh
#chmod +x lusca_install.sh
#nano lusca_install.sh

copas code ini ke dalam file lusca_install.sh
