OpenStack Pakete für RHEL und 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 (controller, compute, network, dashboard, storage etc. nodes).

Warnung

Stellen Sie sicher, dass Ihre Hosts die neuesten verfügbaren Versionen der Grundinstallationspakete für Ihre Distribution enthalten, bevor Sie fortfahren.

Warnung

The following instructions refer to RDO: a free, community supported distribution of OpenStack for RHEL and CentOS. For the Red Hat-supported Red Hat OpenStack Platform, see here.

According to RDO Packstack documentation, RDO should work on RHEL but is currently only tested on CentOS Stream.

Bemerkung

Deaktivieren Sie sämtliche automatischen Aktualisierungsdienste, um deren Einfluss auf Ihre OpenStack-Umgebung auszuschließen.

Warnung

We recommend disabling EPEL when using RDO packages due to updates in EPEL breaking backwards compatibility. Or, preferably pin package versions using the dnf versionlock plugin (if unavailable please use dnf install 'dnf-command(versionlock)').

If EPEL is needed, also consider lowering its priority in DNF.

CentOS Stream

Enable PowerTools/CRB repository:

# ### CentOS Stream 9
# dnf install dnf-plugins-core
# dnf config-manager --set-enabled crb

RHEL

  • When using RHEL, it is assumed that you have registered your system using Red Hat Subscription Management. For more information on registering a RHEL 9 system, see the Red Hat Enterprise Linux 9 Installation Guide.

  • Enable the required repositories:

    # ### RHEL 9
# subscription-manager repos --enable=rhel-9-for-x86_64-baseos-rpms \
   --enable=rhel-9-for-x86_64-appstream-rpms \
   --enable=rhel-9-for-x86_64-supplementary-rpms

  • Enable CodeReady Linux Builder (CRB) repository:

    # ### RHEL 9
# subscription-manager repos --enable=codeready-builder-for-rhel-9-x86_64-rpms

Aktivieren Sie das OpenStack-Repository

To choose which OpenStack release to install, check the release page.

CentOS Stream

  • On CentOS Stream, 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:

    # ### CentOS Stream 9
# dnf install centos-release-openstack-<release>

# ### So for example
# ### 2024.2 Dalmatian
# dnf install centos-release-openstack-dalmatian
# ### 2024.1 Caracal
# dnf install centos-release-openstack-caracal
# ### 2023.2 Bobcat
# dnf install centos-release-openstack-bobcat

RHEL

  • Laden Sie unter RHEL das RDO-Repository-RPM herunter und installieren Sie es zur Aktivierung des OpenStack-Repositories.

    # ### RHEL 9
# dnf install https://trunk.rdoproject.org/rdo_release/rdo-release.el9s.rpm

    The RDO repository RPM installs the latest available OpenStack release.

Schließen Sie die Installation ab

  1. Aktualisieren Sie die Pakete auf allen Knoten:

    # dnf upgrade

    Bemerkung

    Wenn das Upgrade einen neuen Kernel enthält, starten Sie den Host neu, um den Kernel zu aktivieren.

  2. Install the appropriate OpenStack client for your version.

    # ### EL9
# dnf install python3-openstackclient

  3. RHEL und CentOS aktivieren standardmäßig SELinux. Installieren Sie das Paket openstack-selinux, um Sicherheitsrichtlinien für OpenStack-Dienste automatisch verwalten zu lassen:

    # ### EL9
# dnf install openstack-selinux
