Belajar Linux ID – Pada tutorial kali ini kita akan mencoba install openstack multi-node. Arti dari multi-node sendiri yaitu lebih dari 1 VM atau server yang digunakan dalam instalasi Openstack, dan pada tutorial kali ini kita akan membagi beberapa part untuk instalasi openstack nya karena tahapaannya yang cukup panjang.
[Baca juga: OPENSTACK 01: DEFINISI DAN ARSITEKTUR]
[Baca juga: OPENSTACK 02: INSTALL OPENSTACK ALL-IN-ONE WITH PACKSTACK]
Kali ini kita tetap menggunakan packstack untuk instalasi openstack nya. Dan disini kami akan menggunakan 2 node dengan masing – masing rincian dan spesifikasi VM sebagai berikut
# Node Controller
OS: CentOS 7
RAM: 8 GB
CPU: 4 Core
Disk: 60 GB
IP Management [eth1]: 10.36.36.10/24
IP External [eth2]: 10.136.136.10/24
Hostname: hamim-controller.nurhamim.my.id
Volume: 30 GB
# Node Compute
OS: CentOS 7
RAM: 8 GB
CPU: 4 Core
Disk: 60 GB
IP Management [eth1]: 10.36.36.20/24
IP External [eth2]: 10.136.136.20/24
Hostname: hamim-compute.nurhamim.my.id
Berikut tahapan – tahapan instalasinya.
Silakan remote SSH ke masing – masing node, dan pastikan setiap node sudah memiliki 2 interface ip private yang sudah ditentukan diatas, silakan disesuaikan dengan kondisi Anda masing – masing
