Openstack installatie 2

Openstack installeren is erg makkelijk. Dit kan je op een eigen server doen maar ook in een VM. Hou er wel rekening mee dat geheugen en CPU voldoende aanwezig moeten zijn.

Volg de Quickstart van Red Hat en je heb je eigen cloud.

De prerequisites zijn echter niet volledig beschreven om de installatie volledig te laten afronden.

Zorg tenminste dat je:

• genoeg geheugen heb
• je / (root) minimaal 20G groot is
• je /var minimaal 20G groot is
• je nog vrije ruimte over heb in je lvm

Dus:

• installeer je CentOS server
• yum -y update
• ssh-keygen
• ssh-copy-id -i .ssh/id_rsa.pub root@[servernaam]
• reboot
• yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
• yum install -y openstack-packstack
• packstack –allinone
• alle vragen kan je  simpel door enteren, voor wachtwoorden is het altijd verstandig om iets veiligs te kiezen.
• wacht, serieus, dit gaat wel een poosje duren (bij mij 48 min)

De vragen die gesteld gaan worden zijn

[root@matrix ~]# time packstack –allinone

Proceed with the configuration listed above? (yes|no): 

Na installatie staat er op het scherm dat je kan inloggen.

• http://<serverip>/dashboard
• http://<serverip>/nagios

Je inlognaam zal admin zijn, je password staat in de keystonerc_admin in je home. Voor nagios moet je de packstack-answers-[datum]-[tijd].txt file even doorlezen. Of login en doe een

cat packstack-answers-* | grep NAGIOS_PW

Je heb nu een (web)omgeving om je nieuwe cloud te bekijken.

Een vervolg stap zal zijn om je netwerk op orde te maken, hier kom ik (hopelijk) later op terug.
