centos系统openstack服务器,RHEL和CentOS的OpenStack软件包
RHEL和CentOS的OpenStack软件包¶
由于不同的发布日程，发行版发布 OpenStack 的包作为发行版的一部分，或使用其他方式。请在所有节点上执行这些程序。
警告
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.
注解
这里所描述的OpenStack包设置需要在所有节点进行：控制节点、计算节点和块存储节点。
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。
注解
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
当使用RDO包时，我们推荐禁用EPEL，原因是EPEL中的更新破坏向后兼容性。或者使用``yum-versionlock``插件指定包版本号。
注解
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.
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:
#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.
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:
#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
启用OpenStack库¶
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:
#yum install centos-release-openstack-victoria
#yum config-manager --set-enabled PowerTools
When installing the Ussuri release, run:
#yum install centos-release-openstack-ussuri
#yum config-manager --set-enabled PowerTools
When installing the Train release, run:
#yum install centos-release-openstack-train
When installing the Stein release, run:
#yum install centos-release-openstack-stein
When installing the Rocky release, run:
#yum install centos-release-openstack-rocky
When installing the Queens release, run:
#yum install centos-release-openstack-queens
When installing the Pike release, run:
#yum install centos-release-openstack-pike
在RHEL上，下载和安装RDO仓库RPM来启用OpenStack仓库。
On RHEL 7:
#yum install https://rdoproject.org/repos/rdo-release.rpm
On RHEL 8:
#dnf install https://www.rdoproject.org/repos/rdo-release.el8.rpm
The RDO repository RPM installs the latest available OpenStack release.
完成安装¶
Upgrade the packages on all nodes:
#yum upgrade
注解
如果更新了一个新内核，重启主机来使用新内核。
Install the appropriate OpenStack client for your version.
For CentOS 7 and RHEL 7
#yum install python-openstackclient
For CentOS 8 and RHEL 8
#yum install python3-openstackclient
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：
#yum install openstack-selinux
