Install operating system on each node

The first step in setting up your highly-available OpenStack cluster is to install the operating system on each node. Follow the instructions in the OpenStack Installation Guides:

• CentOS and RHEL
• openSUSE and SUSE Linux Enterprise Server
• Ubuntu

The OpenStack Installation Guides also include a list of the services that use passwords with important notes about using them.

This guide uses the following example IP addresses:

# controller
10.0.0.11       controller # virtual IP
10.0.0.12       controller1
10.0.0.13       controller2
10.0.0.14       controller3
