RHEL和CentOS的OpenStack软件包

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).

警告

在你进行更多步骤前，你的主机必须包含最新版本的基础安装软件包。

警告

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.

备注

禁用或移除所有自动更新的服务，因为它们会影响到您的 OpenStack 环境。

先决条件

警告

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

启用OpenStack库

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

  • 在RHEL上，下载和安装RDO仓库RPM来启用OpenStack仓库。

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

    The RDO repository RPM installs the latest available OpenStack release.

完成安装

  1. Upgrade the packages on all nodes:

    # dnf upgrade

    备注

    如果更新了一个新内核，重启主机来使用新内核。

  2. Install the appropriate OpenStack client for your version.

    # ### EL9
# dnf install python3-openstackclient

  3. RHEL和 CentOS 默认启用 SELinux 。安装 openstack-selinux 包实现对OpenStack服务的安全策略进行自动管理：

    # ### EL9
# dnf install openstack-selinux
