chapter 3 Installing Fedora Now comes the moment of truth. You’ve done the homework, figured out how you want to install your copy of Fedora, and you’re ready to go. This chapter won’t disappoint you. Its sole goal is to walk you through the installation process using the Anaconda graphical installer. Along the way, you will: ■ Discover how to explore Fedora—without installing it. ■ Choose which option will be best for you, installing Fedora alone or along- side another operating system. ■ Journey step by step through the installation process. ■ Create one or more users for your Fedora machine. Try Before You Buy © Cengage Learning. All rights reserved. No distribution allowed without express authorization. This section may leave you scratching your head and wondering why you just went through all of the preparation in Chapter 2. Be patient, there’s a method to this madness. All spins of Fedora are currently available to users as a LiveCD version. “LiveCD” is the label for operating systems that can be booted and run right from the CD itself—without installing on your computer’s hard drive. 41 Game Developing GWX Not For Sale Not For Sale 42 Chapter 3 ■ Installing Fedora This means that when you insert your Fedora CD into the disc drive and restart your computer, Fedora will automatically begin running on your computer without putting on any new files or touching pre-existing data on your machine. Fedora just starts up and runs. So why, you ask, should I bother installing Fedora at all? I can just run it from the CD. -
Quick-And-Easy Deployment of a Ceph Storage Cluster with SLES with a Look at SUSE Studio, Manager and Build Service
Quick-and-Easy Deployment of a Ceph Storage Cluster with SLES With a look at SUSE Studio, Manager and Build Service Jan Kalcic Flavio Castelli Sales Engineer Senior Software Engineer [email protected] [email protected] Agenda Ceph Introduction System Provisioning with SLES System Provisioning with SUMa 2 Agenda Ceph Introduction SUSE Studio System Provisioning with SLES SUSE Manager System Provisioning with SUMa 3 Ceph Introduction What is Ceph • Open-source software-defined storage ‒ It delivers object, block, and file storage in one unified system • It runs on commodity hardware ‒ To provide an infinitely scalable Ceph Storage Cluster ‒ Where nodes communicate with each other to replicate and redistribute data dynamically • It is based upon RADOS ‒ Reliable, Autonomic, Distributed Object Store ‒ Self-healing, self-managing, intelligent storage nodes 5 Ceph Components Monitor Ceph Storage Cluster Object Storage Device (OSD) Ceph Metadata Server (MDS) Ceph Block Device (RBD) Ceph Object Storage (RGW) Ceph Clients Ceph Filesystem Custom implementation 6 Ceph Storage Cluster • Ceph Monitor ‒ It maintains a master copy of the cluster map (i.e. cluster members, state, changes, and overall health of the cluster) • Ceph Object Storage Device (OSD) ‒ It interacts with a logical disk (e.g. LUN) to store data (i.e. handle the read/write operations on the storage disks). • Ceph Metadata Server (MDS) ‒ It provides the Ceph Filesystem service. Purpose is to store filesystem metadata (directories, file ownership, access modes, etc) in high-availability Ceph Metadata Servers 7 Architectural Overview 8 Architectural Overview 9 Deployment Overview • All Ceph clusters require: ‒ at least one monitor ‒ at least as many OSDs as copies of an object stored on the cluster • Bootstrapping the initial monitor is the first step ‒ This also sets important criteria for the cluster, (i.e. -
