Virtual Private Server (VPS), juga dikenal dengan Virtual Dedicated Server (VDS) atau Virtual Server adalah teknologi server side tentang operating system dan software yang memungkinkan sebuah mesin dengan kapasitas besar di bagi ke beberapa virtual mesin. Tiap virtual mesin ini melayani operating system dan software secara independen dan dengan konfigurasi yang cepat.

Salah satu solusi membangun VPS adalah menggunakan OpenVZ. OpenVZ menawarkan solusi server virtualization dalam sistem operasi Linux.  Tutorial Installation dan  Managing OpenVZ yang saya implementasikan diterapkan pada Sistem operasi Debian 5 (Lenny).  Hasil akhirnya adalah membuat banyak server VPS dengan hardware yang sama. Jika sudah berhasil mengimplementasikan teknologi virtualisasi ini, tak elok rasanya jika tidak berbagi ilmu dengan yang lain. Untuk ini saya dokumentasikan hasil instalasi disalah satu server vps yang terletak di Gedung Cyber Mampang Jakarta.

Sistem operasi yang sudah siap Debian 5 (Lenny),  beberapa IP Publik dengan koneksi internet.

Sistem operasi Linux Debian versi 5 sudah memuat Openvz kernel packages dan tools pada main repositorynya. Jika sistem operasinya versi sebelum 5, diharapkan upgrade dahulu ke versi Lenny ini. Setelah mendapat root dan password serta ip publik pemilik server ini, aku pun langsung meluncur ke server tersebut menggunakan ssh. Berikut dokumentasinya :

– Diawal kernel masih memakai bawaan debian lenny.
