Packages OpenStack pour RHEL et 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).

Avertissement

Vos hôtes doivent contenir la dernière version des packages d’installation de base disponible pour votre distribution avant d’aller plus loin.

Avertissement

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.

Note

Désactiver ou supprimer tout service de mise à jour automatique parce qu’il peut impacter votre environnement OpenStack.

Pré-requis

Avertissement

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

Activer le dépôt OpenStack

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

  • Sur RHEL, télécharger et installer le RPM dépôt RDO pour activer le dépôt OpenStack.

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

    The RDO repository RPM installs the latest available OpenStack release.

Finaliser l’installation

  1. Mettre à jour les packages sur tous les noeuds :

    # dnf upgrade

    Note

    Si le processus d’upgrade inclut un nouveau noyau, redémarrer votre hôte pour l’activer.

  2. Install the appropriate OpenStack client for your version.

    # ### EL9
# dnf install python3-openstackclient

  3. RHEL et CentOS active SELinux par défaut. Installer le package openstack-selinux pour gérer automatiquement les polices de sécurité pour les services OpenStack :

    # ### EL9
# dnf install openstack-selinux
