Installing the operating system

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 Environment section of the Installation Tutorials and Guides depending on your distribution.

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

Note

Before following this guide to configure the highly available OpenStack cluster, ensure the IP 10.0.0.11 and hostname controller are not in use.

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
