Chapter 2. Installing OpenStack

Installing, configuring, and maintaining OpenStack clouds can be an arduous task when performed by hand. Many third-party vendors offer downloadable cloud software based on OpenStack that provide deployment and management strategies using Chef, Puppet, Fuel, Ansible, and other tools.

This chapter will guide you through a package-based installation of the following OpenStack components on the CentOS operating system:

Keystone
Glance
Nova Compute
Horizon

The installation process documented within this chapter is based on the OpenStack Installation Guide for Red Hat Enterprise Linux, CentOS, and Fedora, that is found at http://docs.openstack.org/.

If you'd rather download a third-party cloud distribution based on OpenStack, try one of the following:

Rackspace Private Cloud: http://www.rackspace.com/cloud/private/
RedHat RDO: http://openstack.redhat.com/
Mirantis OpenStack: http://software.mirantis.com/
Piston Cloud: http://www.pistoncloud.com/
