OpenStack packages

Distributions might release OpenStack packages as part of their distribution or through other methods because the OpenStack and distribution release times are independent of each other.

This section describes the configuration you must complete after you configure machines to install the latest OpenStack packages.

The examples in this guide use the OpenStack packages from the RDO repository. These packages work on Red Hat Enterprise Linux 6, compatible versions of CentOS, and Fedora 20. To enable the RDO repository, download and install the rdo-release-icehouse package:

# yum install http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-3.noarch.rpm

The EPEL package includes GPG keys for package signing and repository information. This should only be installed on Red Hat Enterprise Linux and CentOS, not Fedora. Install the latest epel-release package (see http://download.fedoraproject.org/pub/epel/6/x86_64/repoview/epel-release.html). For example:

# yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

The openstack-utils package contains utility programs that make installation and configuration easier. These programs are used throughout this guide. Install openstack-utils. This verifies that you can access the RDO repository:

# yum install openstack-utils

	Warning
	The openstack-config program in the openstack-utils package uses crudini to manipulate configuration files. However, crudini version 0.3 does not support multi valued options. See https://bugs.launchpad.net/openstack-manuals/+bug/1269271. As a work around, you must manually set any multi valued options or the new value overwrites the previous value instead of creating a new option.

The openstack-selinux package includes the policy files that are required to configure SELinux during OpenStack installation on RHEL and CentOS. This step is not required during OpenStack installation on Fedora. Install openstack-selinux:

# yum install openstack-selinux

Upgrade your system packages:

# yum upgrade

If the upgrade included a new kernel package, reboot the system to ensure the new kernel is running:

# reboot
