OpenStack system consists of several key services that are separately installed. These services worktogether depending on your cloud needs and include the Compute, Identity, Networking, Image, BlockStorage, Object Storage, Telemetry, Orchestration, and Database services. You can Install any of theseprojects separately and con gure them stand-alone or as connected of con guration options and sample con guration les are Guide documents the installation of OpenStack starting with the Pike release.

6 It covers :This Guide is a work-in-progress and is subject to updates frequently. Pre-release packageshave been used for testing, and some instructions may not work with nal versions. Please help usmake this Guide better by reporting any errors you systemsCurrently, this Guide describes OpenStack installation for the following Linux distributions:openSUSE and SUSE Linux Enterprise ServerYou can Install OpenStack by using packages onopenSUSE Leap , openSUSE Leap 15, SUSE Linux Enterprise Server 12 SP4, SUSE LinuxEnterprise Server 15 through the Open Build Service Cloud Hat Enterprise Linux and CentOSYou can Install OpenStack by using packages available onboth Red Hat Enterprise Linux 7 and 8 and their derivatives through the RDO.

7 OpenStack Wallaby is available for CentOS Stream 8. OpenStack Ussuri and Victoriaare available for both CentOS 8 and RHEL 8. OpenStack Train and earlier are available on bothCentOS 7 and RHEL can walk through an installation by using packages available through Canonicals UbuntuCloud archive repository for Ubuntu + (LTS).Note:The Ubuntu Cloud Archive pockets for Pike and Queens provide OpenStack packages forUbuntu LTS; OpenStack Queens is installable direct using Ubuntu LTS; the Ubuntu3 Install GuideCloud Archive pockets for Rocky and Stein provide OpenStack packages for Ubuntu LTS;the Ubuntu Cloud Archive pocket for Victoria provides OpenStack packages for Ubuntu 2.

8 PrefaceCHAPTERTHREEGET STARTED WITH OPENSTACKThe OpenStack project is an open source cloud computing platform for all types of clouds, which aimsto be simple to implement, massively scalable, and feature rich. Developers and cloud computing tech-nologists from around the world create the OpenStack provides anInfrastructure-as-a-Service (IaaS)solution through a set of interrelated service offers anApplication Programming Interface (API)that facilitates this integration. Depend-ing on your needs, you can Install some or all OpenStack servicesTheOpenStack project navigatorlets you browse the OpenStack services that make up the OpenStackarchitecture.

9 The services are categorized per the service type and release OpenStack architectureThe following sections describe the OpenStack architecture in more detail:5 Install architectureThe following diagram shows the relationships among the OpenStack architectureTo design, deploy, and con gure OpenStack , administrators must understand the logical shown inConceptual architecture, OpenStack consists of several independent parts, named the Open-Stack services. All services authenticate through a common Identity service. Individual services interactwith each other through public APIs, except where privileged administrator commands are , OpenStack services are composed of several processes.

10 All services have at least one APIprocess, which listens for API requests, preprocesses them and passes them on to other parts of theservice. With the exception of the Identity service, the actual work is done by distinct communication between the processes of one service, an AMQP message broker is used. The ser-vices state is stored in a database. When deploying and con guring your OpenStack cloud, you canchoose among several message broker and database solutions, such as RabbitMQ, MySQL, MariaDB,and can access OpenStack via the web-based user interface implemented by the Horizon Dashboard,viacommand-line clientsand by issuing API requests through tools like browser plug-ins orcurl.
