Before you begin

Before you can install OpenStack, some work must be done to prepare the system for a successful installation.

Permissions

OpenStack services can be installed either as root or as a user with sudo permissions. The latter may require that the user be added to the sudoers file on each host. For tips on configuring sudoers, please visit the following URL:

For this installation, all commands should be run as root unless specified otherwise.

Installation of OpenStack on CentOS uses packages from the RedHat RDO repository. To enable the RDO repository, download and install the rdo-release-havana package on all hosts:

# rpm -ivh http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-8.noarch.rpm ...
