OpenStack packages

Distributions release OpenStack packages as part of the distribution or using other methods because of differing release schedules. Perform these procedures on all nodes.

Note

The set up of OpenStack packages described here needs to be done on all nodes: controller, compute, and Block Storage nodes.

Warning

Your hosts must contain the latest versions of base installation packages available for your distribution before proceeding further.

Note

Disable or remove any automatic update services because they can impact your OpenStack environment.

ubuntu

Enable the OpenStack repository

# apt install software-properties-common
# add-apt-repository cloud-archive:newton

rdo

Prerequisites

Warning

We recommend disabling EPEL when using RDO packages due to updates in EPEL breaking backwards compatibility. Or, preferably pin package versions using the yum-versionlock plugin.

Note

CentOS does not require the following steps.

1. On RHEL, register your system with Red Hat Subscription Management, using your Customer Portal user name and password:

   # subscription-manager register --username="USERNAME" --password="PASSWORD"

2. Find entitlement pools containing the channels for your RHEL system:

   # subscription-manager list --available

3. Use the pool identifiers found in the previous step to attach your RHEL entitlements:

   # subscription-manager attach --pool="POOLID"

4. Enable required repositories:

   # subscription-manager repos --enable=rhel-7-server-optional-rpms \
     --enable=rhel-7-server-extras-rpms --enable=rhel-7-server-rh-common-rpms

rdo

Enable the OpenStack repository

• On CentOS, the extras repository provides the RPM that enables the OpenStack repository. CentOS includes the extras repository by default, so you can simply install the package to enable the OpenStack repository.

  # yum install centos-release-openstack-newton

• On RHEL, download and install the RDO repository RPM to enable the OpenStack repository.

  # yum install https://rdoproject.org/repos/rdo-release.rpm

obs

Enable the OpenStack repository

• Enable the Open Build Service repositories based on your openSUSE or SLES version:

  On openSUSE:

  # zypper addrepo -f obs://Cloud:OpenStack:Newton/openSUSE_Leap_42.2 Newton

  Note

  The openSUSE distribution uses the concept of patterns to represent collections of packages. If you selected 'Minimal Server Selection (Text Mode)' during the initial installation, you may be presented with a dependency conflict when you attempt to install the OpenStack packages. To avoid this, remove the minimal_base-conflicts package:

  # zypper rm patterns-openSUSE-minimal_base-conflicts

  On SLES:

  # zypper addrepo -f obs://Cloud:OpenStack:Newton/SLE_12_SP2 Newton

  Note

  The packages are signed by GPG key D85F9316. You should verify the fingerprint of the imported GPG key before using it.

  Key Name:         Cloud:OpenStack OBS Project <Cloud:OpenStack@build.opensuse.org>

debian

Enable the backports repository

The Newton release is available directly through the official Debian backports repository. To use this repository, follow the instruction from the official Debian website, which basically suggest doing the following steps:

1. On all nodes, adding the Debian 8 (Jessie) backport repository to the source list:

   # echo "deb http://http.debian.net/debian jessie-backports main" \
     >>/etc/apt/sources.list

   Note

   Later you can use the following command to install a package:

   # apt -t jessie-backports install ``PACKAGE``

Finalize the installation

1. Upgrade the packages on your host:

   ubuntu or debian

   # apt update && apt dist-upgrade

   rdo

   # yum upgrade

   obs

   # zypper refresh && zypper dist-upgrade

   Note

   If the upgrade process includes a new kernel, reboot your host to activate it.

2. Install the OpenStack client:

   debian or ubuntu

   # apt install python-openstackclient

   rdo

   # yum install python-openstackclient

   obs

   # zypper install python-openstackclient

rdo

3. RHEL and CentOS enable SELinux by default. Install the openstack-selinux package to automatically manage security policies for OpenStack services:

   # yum install openstack-selinux
