Checking Your System ConfigurationYaSTIncluded with OpenSUSEUI tool to customize the OS during and after installationSystem configuration determines how openSUSE is installedDesktopLaptopServer*



Checking Your System Configuration (contd.)*Figure 2-1 An overview of installation steps in YaSTCengage Learning 2013



Requirements for Installing LinuxMost software installations run more smoothly if computer exceeds the minimum requirementsMinimum requirementsPentium III 500 MHz or higher processor512 MB RAM3 GB free disk space800 600 display resolution*



Requirements for Installing Linux (contd.)Recommended requirementsPentium 4 2.4 GHz or higher, any AMD64, or an Intel EM64T processor1 GB RAMMore than 3 GB free disk space1024 768 or higher display resolution*



The Unified Installation Method with Virtual MachinesServer farmsGroups of servers networked together in a single locationVirtual machine (VM) Software container with its own OS, IP address, and applicationsHostPhysical computer where the virtual machine runs GuestVirtual machine using the hosts physical hardware resources*



The Unified Installation Method with Virtual Machines (contd.)Benefits of virtualization:Run multiple OSs on one machineTest applications before actually installing them on a host machineReduce costs by decreasing the physical hardware that must be purchased for a networkExperiment with untested programs without infecting host machines with viruses or other malware*



The Unified Installation Method with Virtual Machines (contd.)Table 2-1 Overview of some virtualization software packages*


*Table 2-1 Virtualization software packagesLinux Operations and Administration



Overview of VMware PlayerVMware Player 3.1.5 Free application Create, configure, and run virtual machines on a Windows or Linux systemRequirements for the host machine:ArchitectureStandard x86-compatible or x86-64 with Intel VT or AMD-Vcompatible PCProcessor speed1.3 GHz or faster*



Overview of VMware Player (contd.)MemoryMinimum 1 GB, but 2 GB or more recommendedHard diskAt least 1 GB free disk space recommended for each guest OSActivity 2-1: Downloading VMware PlayerRegister a VMware account Download VMware Player 3.0*



Installing VMware Player on a Windows HostUse the VMware-player-xxxxxx.exe installation filexxxxxx represents the version and build numbersActivity 2-2: Installing VMware Player 3.1.5 on a Windows HostInstall VMware Player, a free program for creating, configuring, and running virtual machines*



Installing OpenSUSEOpenSUSE Free, open-source Linux OSDownload, install, and use the software at no cost as well as view and change the source codeDownload International Organization for Standardization (ISO) image file http://software.openSUSE.org/112/enISO image Archive file containing the contents of a CD or DVDVirtual CD or DVD is a digital replica of a physical CD or DVD

Installing OpenSUSE (contd.)Installation divided into three main phases: Preparation, installation, and configurationPreparation phase InteractiveSelect the language, time zone, desktop environment, hard disk setup, and user account and password*



Installing OpenSUSE (contd.)Installation phase Not interactiveConfiguration phaseSet up the network, Internet access, and hardware componentsActivity 2-3: Creating a Virtual MachineCreate a virtual machine that can be used for installing an OS*



OpenSUSE Boot OptionsOpenSUSE Boot Options windowDisplays options for the installation procedureTable 2-2 explains the optionsAdditional options:F1 HelpContext sensitive helpF2 LanguageChange the display language and corresponding keyboard layoutF3 Video ModeSelect a screen resolution, or select Text Mode

Installation ModeChoices for installation:InstallationUpdateRepair Installed SystemOther optionsUse Automatic Configuration option Selected by default Used when performing a new installationInclude Add-On Products from Separate Media option Install add-ons from software repositories*



Clock and Time ZoneSelect region and time zoneHardware clock set to Universal Time Coordinated (UTC) by defaultWill switch from standard time to daylight savings time and back automatically*



Desktop SelectionChoose the environment: GNOME or KDEOther choices for desktop:XFCE DesktopMinimal X WindowMinimal Server Selection (Text Mode)*



Suggested PartitioningYaST checks hard disk and displays a proposed partition setup Edit Partition Setup buttonChange the partition setupLogical Volume Management (LVM) Creates virtual partitions that can span physical hard drivesMultiboot configuration Install multiple OSs on one computer Choose which one to use when computer boots*



Create New UserCreate a local user and set the passwordUse this password for system administrator option Allows using the same password supplied for the user to access the system administrator (root) accountReceive System Mail optionAllows the user to receive system service messagesAutomatic Login optionBoot straight to your desktop instead of being prompted for a username and password*



The Installation PhaseAfter preparation phase YaST displays installation settingsAlter settings by clicking the headers for each section or clicking the Change buttonRunlevel Operating state of the Linux OSEach runlevel offers different servicesCan change the runlevel system boots to*



The Installation Phase (contd.)*Table 2-3 openSUSE Linux runlevels



Performing the InstallationTakes about 15 minutesClick the Details tab at any timeView installation logAfter installation is finishedComputer restarts in the configuration phase*



The Configuration PhaseAutomatic Configuration optionConfiguration process is done automatically*



Hostname and Domain NameHostname Computers machine name in the networkDomain name Name of the network the host belongs toDynamic Host Configuration Protocol (DHCP) Networking protocol Assigns IP addresses and other network configuration information to hosts automatically/etc/hosts file Map hostnames to IP addresses*
