Preparing A CentOS Server For Platform9 Managed OpenStack
This document describes how prepare a CentOS Linux physical server to be added to Platform9 Managed OpenStack.
Step 1 – Install CentOS Operating System
Make sure that your server is configured appropriately with access to storage and physical networking.
Download and install CentOS 7.3 on your physical server. You can download CentOS distributions from here: http://wiki.centos.org/Download.
Note: We recommend installing the minimal CentOS operating system. Platform9 agents are prepared to pull in any required package dependencies and get them installed on your server to prepare it to be part of OpenStack. This includes any libvirt/KVM package dependencies.
It’s usually a good practice to get your system up to date with regard to the latest patches and updates.
sudo yum -y update
Step 2 – Ensure Virtualization is Enabled
Ensure that virtualization is enabled for your server by checking your server’s BIOS settings. If disabled, enable virtualization for the server to be able to act as a hypervisor within Platform9 Managed OpenStack.
Step 3 – Ensure the System Clock is Synchronized
Your host will fail to authenticate with Platform 9 services if its date / time settings are incorrect. Type
date to verify that the current date and time are correct. If they aren’t, then one possible fix is to enable the network time protocol daemon service:
sudo yum -y install ntp chkconfig --add ntpd service ntpd start
That’s it! At this point, your CentOS server is ready to be prepared with rest of storage and networking pre-requisites to be added to Platform9 Managed OpenStack.
