SOLUSINYA apa ?

Masuk ke host OpenVZ, disini Host dan kontainer OpenVZ menggunakan sistem operasi Debian Linux 5.5 :

#vzctl exec kontainerzimbra apt-get install ant sysstat gmp compat-libstdc++-296 compat-libstdc++-33

#vzctl exec kontainerzimbra apt-get install fetchmail libtool-ltdl

#vzctl exec kontainerzimbra ant

Jika diperlukan menambahkan memory pada kontainerzimbra.
Selesai , tinggal install ulang Zimbra nya pada kontainerzimbra

#./install.sh -u

#./install.sh

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 :
