Updated the install guide for Victoria. NOTE: I did not update environment-packages-obs.rst so OpenSUSE is still Ussuri. Change-Id: I967b2455bbc164b42ce90d7cc607b623d7800c01

OpenStack packages for RHEL and CentOS
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Distributions release OpenStack packages as part of the distribution or
|
|
using other methods because of differing release schedules. Perform
|
|
these procedures on all nodes.
|
|
|
|
.. warning::
|
|
|
|
Starting with the Ussuri release, you will need to use either CentOS8
|
|
or RHEL 8. Previous OpenStack releases will need to use either CentOS7
|
|
or RHEL 7. Instructions are included for both distributions and
|
|
versions where different.
|
|
|
|
.. 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.
|
|
|
|
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::
|
|
|
|
The following steps apply to RHEL only. CentOS does not require these
|
|
steps.
|
|
|
|
#. When using RHEL, it is assumed that you have registered your system using
|
|
Red Hat Subscription Management and that you have the
|
|
``rhel-7-server-rpms`` or ``rhel-8-for-x86_64-baseos-rpms`` repository
|
|
enabled by default depending on your version.
|
|
|
|
For more information on registering a RHEL 7 system, see the
|
|
`Red Hat Enterprise Linux 7 System Administrator's Guide
|
|
<https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/part-Subscription_and_Support.html>`_.
|
|
|
|
#. In addition to ``rhel-7-server-rpms`` on a RHEL 7 system, you also need to
|
|
have the ``rhel-7-server-optional-rpms``, ``rhel-7-server-extras-rpms``,
|
|
and ``rhel-7-server-rh-common-rpms`` repositories enabled:
|
|
|
|
.. code-block:: console
|
|
|
|
# subscription-manager repos --enable=rhel-7-server-optional-rpms \
|
|
--enable=rhel-7-server-extras-rpms --enable=rhel-7-server-rh-common-rpms
|
|
|
|
For more information on registering a RHEL 8 system, see the
|
|
`Red Hat Enterprise Linux 8 Installation Guide
|
|
<https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/performing_a_standard_rhel_installation/post-installation-tasks_installing-rhel>`_.
|
|
|
|
In addition to ``rhel-8-for-x86_64-baseos-rpms`` on a RHEL 8 system, you
|
|
also need to have the ``rhel-8-for-x86_64-appstream-rpms``,
|
|
``rhel-8-for-x86_64-supplementary-rpms``, and ``codeready-builder-for-rhel-8-x86_64-rpms``
|
|
repositories enabled:
|
|
|
|
.. code-block:: console
|
|
|
|
# subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms \
|
|
--enable=rhel-8-for-x86_64-supplementary-rpms --enable=codeready-builder-for-rhel-8-x86_64-rpms
|
|
|
|
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. For CentOS8, you will also need to enable the PowerTools
|
|
repository.
|
|
|
|
**When installing the Victoria release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-victoria
|
|
# yum config-manager --set-enabled PowerTools
|
|
|
|
**When installing the Ussuri release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-ussuri
|
|
# yum config-manager --set-enabled PowerTools
|
|
|
|
**When installing the Train release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-train
|
|
|
|
**When installing the Stein release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-stein
|
|
|
|
**When installing the Rocky release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-rocky
|
|
|
|
**When installing the Queens release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-queens
|
|
|
|
**When installing the Pike release, run:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install centos-release-openstack-pike
|
|
|
|
* On RHEL, download and install the RDO repository RPM to enable the
|
|
OpenStack repository.
|
|
|
|
**On RHEL 7:**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install https://rdoproject.org/repos/rdo-release.rpm
|
|
|
|
**On RHEL 8:**
|
|
|
|
.. code-block:: console
|
|
|
|
# dnf install https://www.rdoproject.org/repos/rdo-release.el8.rpm
|
|
|
|
The RDO repository RPM installs the latest available OpenStack release.
|
|
|
|
Finalize the installation
|
|
-------------------------
|
|
|
|
1. Upgrade the packages on all nodes:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum upgrade
|
|
|
|
.. note::
|
|
|
|
If the upgrade process includes a new kernel, reboot your host
|
|
to activate it.
|
|
|
|
2. Install the appropriate OpenStack client for your version.
|
|
|
|
**For CentOS 7 and RHEL 7**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install python-openstackclient
|
|
|
|
**For CentOS 8 and RHEL 8**
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install python3-openstackclient
|
|
|
|
3. RHEL and CentOS enable :term:`SELinux` by default. Install the
|
|
``openstack-selinux`` package to automatically manage security
|
|
policies for OpenStack services:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install openstack-selinux
|
