Applies to openSUSE Leap 42.1

1 Installation Quick Start

Abstract

Use the following procedures to install a new version of openSUSE® Leap 42.1. This document gives a quick overview on how to run through a default installation of openSUSE Leap on the x86_64 architecture.

1.1 Welcome to openSUSE Leap

For more detailed installation instructions see Chapter 2, Installation with YaST.

1.1.1 Minimum System Requirements

  • any AMD64/Intel* EM64T processor (32-bit processors are not supported)

  • 1 GB physical RAM (2 GB or more recommended)

  • 3 GB available disk space for a minimal install, 5 GB available for a graphical desktop (more recommended)

  • Supports most modern sound and graphics cards, 800 x 600 display resolution (1024 x 768 or higher recommended)

1.1.2 Installing openSUSE Leap

Use these instructions if there is no existing Linux system on your machine, or if you want to replace an existing Linux system.

  1. Insert the openSUSE Leap DVD into the drive, then reboot the computer to start the installation program. On machines with a traditional BIOS you will see the graphical boot screen shown below. On machines equipped with UEFI, a slightly different boot screen is used. Secure boot on UEFI machines is supported.

    Use F2 to change the language for the installer. A corresponding keyboard layout is chosen automatically. See Section 2.2.1.1, “The Boot Screen on Machines Equipped with Traditional BIOS” or Section 2.2.1.2, “The Boot Screen on Machines Equipped with UEFI” for more information about changing boot options.

  2. Select Installation on the boot screen, then press Enter. This boots the system and loads the openSUSE Leap installer.

  3. The Language and Keyboard Layout are initialized with the language settings you have chosen on the boot screen. Change them here, if necessary.

    Read the License Agreement. It is presented in the language you have chosen on the boot screen. License Translations are available. Proceed with Next.

  4. In case no network interface could be configured automatically via DHCP, the Network Settings dialog opens. If you prefer to install openSUSE Leap with no network connection, choose Next to proceed. However, configuring the network at this stage is recommended, since it will allow to install the latest updates and security fixes from the online update repository. A working network connection will also give you access to additional software repositories. This step is skipped if a network interface was successfully configured via DHCP.

    To configure the network, choose a network interface from the list and click Edit to change its settings. Use the tabs to configure DNS and routing. See Book “Reference”, Chapter 13 “Basic Networking”, Section 13.4 “Configuring a Network Connection with YaST” for more details.

  5. A system analysis is performed, where the installer probes for storage devices, and tries to find other installed systems. When the analasys has finished, the Installation Options screen launches.

    You have got two choices:

    Add Online Repositories Before Installation

    Adds the online software sources (so-called repositories) for openSUSE Leap from http://download.opensuse.org/distribution/leap/. It also adds the update repository for openSUSE Leap. This ensures that the system will be installed with the most current packages without having to apply the updates after installation. Activating this option is recommended. Later during the installation workflow, you will be able to specify which repositories to add.

    Include Add-On Products from Separate Media

    This option allows you to add additional software repositories to openSUSE Leap, that are not provided on http://download.opensuse.org/distribution/leap/. Such add-on products may include third-party products and drivers or additional software for your system. Later during the installation workflow, you will be able to specify which repositories to add.

    Tip
    Tip: Release Notes

    From this point on, the Release Notes can be viewed from any screen during the installation process by selecting Release Notes.

  6. Review the partition setup proposed by the system. If necessary, change it. You have the following options:

    Edit Proposal Settings

    Lets you change options for the proposed settings, but not the suggested partition layout itself.

    Create Partition Setup

    Select a disk to which to apply the proposal.

    Expert Partitioner

    Opens the Expert Partitioner described in Book “Reference”, Chapter 5 “Advanced Disk Setup”, Section 5.1 “Using the YaST Partitioner”.

    To accept the proposed setup without any changes, choose Next to proceed.

  7. Select the clock and time zone to use in your system. To manually adjust the time or to configure an NTP server for time synchronization, choose Other Settings. See Section 2.8, “Clock and Time Zone” for detailed information. Proceed with Next.

  8. If you have selected Add Online Repositories Before Installation earlier during the installation, the List of Online Repositories screen lets you choose which official openSUSE Leap online repositories to add. The default selection is the recommended choice. In case you would also like to have the repository hosting the sources for the complete distribution, add Main Repository (Sources). The Debug repositories as well as the Untested Updates are for experts and beta testers only.

    After having proceeded with Next, you need to confirm the license agreement for the online repositories with Next.

  9. If you have selected Include Add-On Products from Separate Media earlier during the installation, the Add-On Product step lets you add addtitional repositories.

    Activate I would like to install an additional Add-On Product. Specify a media type, a local path or a network resource hosting the repository and follow the on-screen instructions.

    Check Download Repository Description Files to download the files describing the repository now. If deactivated, they will be downloaded after the installation has started. Proceed with Next and insert a medium if required. Depending on the product's content it may be necessary to accept additional license agreements. Proceed with Next. Add-On products can also be installed at any time later from the running system as described in Chapter 10, Installing Add-On Products.

    Note
    Note: The Add-On Product Installation Screen

    In case you have also configured the product online repositories, you will not see the screen depicted in the screensjot above, but rather a table showing the products online repositories that already have been added. Choose Add to advance to the Add-On Product screen.

  10. Select the desktop system you would like to use. KDE and GNOME are among the most widely used desktops on Linux. If you prefer a different desktop, choose Other for more options. The XFCE Desktop and the LXDE Desktop are fast and lightweight desktop environments suitable for modest hardware. With Minimal X Window, install a graphical window manager that allows for running stand-alone X applications and console windows but does not provide the usual integrated desktop functionality. In Minimal Server Selection (Text Mode), only console terminals are available.

  11. To create a local user, type the first and last name in the User’s Full Name field, the login name in the Username field, and the password in the Password field.

    The password should be at least eight characters long and should contain both uppercase and lowercase letters and numbers. The maximum length for passwords is 72 characters, and passwords are case-sensitive.

    For security reasons it is also strongly recommended not to enable the Automatic Login. You should also not Use this Password for the System Administrator but rather provide a separate root password in the next installation step. Mails generated by the system are delivered to the user root by default. Check Receive System Mail if you would rather get them as the user that you have created.

    Selecting Change gets you to the expert options explained in Chapter 3, Managing Users with YaST. Proceed with Next.

  12. Type a password for the system administrator account (called the root user). This step is skipped if you have chosen Use this Password for the System Administrator in the previous step.

    You should never forget the root password! After you entered it here, the password cannot be retrieved. See Section 2.13, “Password for the System Administrator root for more information. Proceed with Next.

    Tip
    Tip: Passwords and Keyboard Layout

    It is recommended to only use characters that are available on an English keyboard. In case of a system error or when you need to start your system in rescue mode a localized keyboard might not be available.

  13. Use the Installation Settings screen to review and—if necessary—change several proposed installation settings. The current configuration is listed for each setting. To change it, click the headline. Some settings, such as firewall or SSH can directly be changed by clicking the respective links.

    Tip
    Tip: Remote Access

    Changes you can make here, can also be made later at any time from the installed system. However, if you need remote access directly after the installation, you should adjust the Firewall and SSH settings by opening the SSH port and enablöing the SSH server.

    Software

    The default scope of software includes the base system and X Window with the selected desktop. Clicking Software opens the Software Selection and System Tasks screen, where you can change the software selection by selecting or deselecting patterns. Each pattern contains several software packages needed for specific functions (for example, Web and LAMP server or a print server). For a more detailed selection based on software packages to install, select Details to switch to the YaST Software Manager. See Chapter 9, Installing or Removing Software for more information.

    Booting

    This section shows the boot loader configuration. Changing the defaults is only recommended if really needed. Refer to Book “Reference”, Chapter 12 “The Boot Loader GRUB 2” for details.

    Firewall and SSH

    By default, the Firewall is enabled with the active network interface configured for the external zone. See Book “Security Guide”, Chapter 15 “Masquerading and Firewalls”, Section 15.4 “SuSEFirewall2” for configuration details.

    The SSH service is disabled by default, its port (22) is closed. Therefore logging in from remote is not possible by default. Click enable and open to toggle these settings.

    Default Systemd Target

    By default, the system boots into the graphical target, with network, multiuser and display manager support. Switch to multi-user if you do not need to log in via display manager.

    System

    View detailed hardware information by clicking System. In the resulting screen you can also change Kernel Settings—see Section 2.14.5, “System for more information.

  14. After you have finalized the system configuration on the Installation Settings screen, click Install. Depending on your software selection you may need to agree to license agreements before the installation confirmation screen pops up. Up to this point no changes have been made to your system. After you click Install a second time, the installation process starts.

  15. During the installation, the progress is shown in detail on the Performing Installation screen.

  16. After the installation routine has finished, the computer is rebooted into the installed system. Log in and start YaST to fine-tune the system. If you are not using a graphical desktop or are working from remote, refer to Book “Reference”, Chapter 1 “YaST in Text Mode” for information on using YaST from a terminal.
