Membuat File Server Keren Menggunakan Lighttpd

Kali ini saya mau berbagi skrip + tutorial cara membuat File Server pada Lighttpd. Nanti file server ini bisa kita gunakan untuk file sharing. Banyak yang nanya, cara bikin seperti http://file.hacker-newbie.org itu gimana? nah, di sini akan saya ajarkan... Yang belum tau Lighttpd itu apa, silahkan Googling dulu. Sudah banyak bertebaran di internet artikel nya. Oke, back to laptop...saya asumsikan anda sudah meng-install Lighttpd dan PHP pada server anda. Kita tidak membutuhkan database di sini. kita akan membuat direktori listing. Syarat yang di butuhkan hanyalah VPS. Kira2 bentuknya dasarnya nanti seperti ini:

Caranya, buat file dir-generator.php pada direktori /var/www/ di Lighttpd anda. Lalu isikan kode berikut:

<?php

$VERSION = "0.3";

Selesai, lalu save...

Penjelasan:

Untuk mengaktifkan menampilkan file/direktori yang tersembunyi, ubah nilai "false" menjadi "true" pada baris berikut:

$ Show_hidden_files = false;

Untuk menggunakan ini, tempatkan file dir-generator.php di document root Anda (/var/www), dan tambahkan baris berikut dalam file lighttpd.conf Anda (biasanya terletak di  /etc /lighttpd /lighttpd.conf ):

dir-listing.activate = "enable" index-file.names = ("/ dir-generator.php")

Seperti yang Anda lihat, ini sangat mudah di kostumisasi. Anda dapat menyertakan style Anda sendiri dalam tag <style> atau link ke file stylesheet, Anda dapat menyertakan favicon, dan setting judul untuk halaman. Ini contoh halaman File Server HN setelah saya modifikasi dng CSS.

Akhir kata, semoga bermanfaat... :)
