OpenStack merupakan salah satu teknologi cloud computing yang banyak dikembangkan dan diterapkan oleh berbagai lembaga, perusahaan, serta organisasi non profit untuk mendukung High Availability, Reliability dan Scalability dalam pemenuhan serta pengingkatan kualitas layanan dengan dapat memungkinkan proses integrasi resource yang sangat tinggi, mulai dari hardware, network, storage dan lainnya. Detail informasi, dokumentasi serta terminologi service atau layanannya dapat diketahui dan ditemukan melalui situs resmi pengembangan projek OpenStack.org tersebut.

Prerequisites

Artikel ini merupakan dokumentasi instalasi OpenStack dengan kondisi infrastruktur yang masih Single Node atau masih menggunakan satu fisik server beserta dengan detail ip address nya yaitu 192.168.137.2/24 dan dengan menggunakan spesifikasi hardwarenya sebagai berikut.

Rekomendasi Sistem Operasi minimum menggunkan Red Hat Enterprise Linux (RHEL) 7 atau dengan versi turunannya seperti CentOS 7 dan Scientific Linux 7 dengan arsitektur x86_64 atau 64 bit, minimum memory 4 GB, prosesor yang sudah mendukung teknologi virtualisasi serta memiliki minimal satu network interface card.

Instalasi

Proses instalasi paket beserta dengan dependensisnya menggunakan perintah yum terhadap server repositori rdoproject.org. Apabila menggunakan sistem operasi GNU/Linux RHEL 7 maka perlu ditambahkan terlebih dahulu server repositori RDO Project tersebut dengan instalasi paket binary file RPM nya melalui perintah yum sebagai berikut.

[root@openstack~]# yum install -y https://www.rdoproject.org/repos/rdo-release.rpm

Namun apabila menggunakan GNU/Linux CentOS 7 terdapat extras repository yang sudah menyediakan paket RPM untuk proses aktifasi OpenStack Repository. Extras repository tersebut sudah aktif secara default didalam GNU/Linux CentOS 7. Proses instalasi RPM untuk konfigurasi OpenStack repository dapat menggunakan perintah yum sebagai berikut.

[root@openstack~]# yum install -y centos-release-openstack-mitaka

Update setiap paket yang telah terinstall di sisi node server terhadap repository server dengan masih menggunakan pertinah yum sebagai berikut.

[root@openstack~]# yum -y update

Install packstack yang berfungsi sebagai utilitas OpenStack installer untuk penerapan Cloud Computing (proof of concept) dalam infrastruktur satu node. Packstack tersebut juga dapat difungsikan untuk penambahan node server sebagai penerapan More High Availabe, More Reliable and More Scalable Cloud Computing dalam infrastruktur Multi Node.

[root@openstack~]# yum install -y openstack-packstack

Setelah packstack terinstall maka selanjutnya proses instalasi OpenStack dalam satu server atau single node.

[root@openstack~]# packstack --allinone

Hasil dari proses instalasinya adalah sebagai berikut.
