Welcome to SUSE Linux Enterprise Server

For more detailed installation instructions and deployment strategies, see the SUSE Linux Enterprise Server Documentation at http://www.suse.com/documentation/.

Minimum System Requirements

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

  • 512 MB physical RAM (1 GB or more recommended)

  • 3.5 GB available disk space (more recommended)

  • 800 x 600 display resolution (1024 x 768 or higher recommended)

Installing SUSE Linux Enterprise Server

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 SUSE Linux Enterprise Server 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 The Boot Screen on Machines Equipped with Traditional BIOS, (↑Deployment Guide) or The Boot Screen on Machines Equipped with UEFI, (↑Deployment Guide) for more information about changing boot options.

  2. Select Installation on the boot screen, then press Enter. This boots the system and loads the SUSE Linux Enterprise Server 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. You need to accept the agreement by checking I Agree to the License Terms to install SUSE Linux Enterprise Server. Proceed with Next.

  4. A system analysis is performed, where the installer probes for storage devices, and tries to find other installed systems. If the network could not be automatically configured while starting the installation system, the Network Settings dialog opens.

    After at least one network interface has been configured you can register your system at the SUSE Customer Center (SCC). Enter the e-mail address associated with your SCC account and the registration code for SUSE Linux Enterprise Server. A successful registration is a prerequisite for getting product updates and being entitled to technical support. Proceed with Next.

    HINT: Installing Product Patches at Installation Time

    If SUSE Linux Enterprise Server has been successfully registered at the SUSE Customer Center, you are asked whether to install the latest available online updates during the installation. If choosing Yes, the system will be installed with the most current packages without having to apply the updates after installation. Activating this option is recommended.

    NOTE: Release Notes

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

  5. After the system is successfully registered, YaST lists modules and extensions that are available for SUSE Linux Enterprise Server from the SUSE Customer Center. The list contains free modules, such as the SUSE Linux Enterprise SDK, or extensions requiring a registration key that is liable for costs. Click an entry to see its description. Optionally select a module or extension for installation by activating its check mark. Proceed with Next.

    Extension Selection
  6. The Add-on Product dialog allows you to add additional software sources (so-called repositories) to SUSE Linux Enterprise Server, that are not provided by the SUSE Customer Center. Such add-on products may include third-party products and drivers or additional software for your system.

    HINT: Adding Drivers During the Installation

    You can also add driver update repositories via the Add-On Products dialog. Driver updates for SUSE Linux Enterprise are provided at http://drivers.suse.com/. These drivers have been created via the SUSE SolidDriver Program.

    If you want to skip this step, proceed with Next. Otherwise activate I would like to Install an 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. If you have chosen an add-on product requiring a registration key, you will be asked to enter it at the Extension and Module Registration Codes page.

  7. Choose the System Role that meets your requirements best. Select Default System for physical machines or virtual guests. For a virtualization host that can run other virtual machines, select KVM Virtualization Host or Xen Virtualization Host.

  8. 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 Section 12.1, Using the YaST Partitioner, (↑Deployment Guide).

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

  9. 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 6.12, Clock and Time Zone, (↑Deployment Guide) for detailed information. Proceed with Next.

  10. 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. Proceed with Next.

  11. Type a password for the system administrator account (called the root user).

    You should never forget the root password! After you entered it here, the password cannot be retrieved. See Section 6.14, Password for the System Administrator root, (↑Deployment Guide) for more information. Proceed with Next.

  12. 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.

    HINT: 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 according to your needs.

    Software

    The default scope of software includes the base system and X Window with the GNOME 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 Section 13.0, Installing or Removing Software, (↑Deployment Guide) for more information.

    Booting

    This section shows the boot loader configuration. Changing the defaults is only recommended if really needed. Refer to Section 12.0, The Boot Loader GRUB 2, (↑Administration Guide) for details.

    Firewall and SSH

    By default, the Firewall is enabled with the active network interface configured for the external zone. See Section 15.4, SuSEFirewall2, (↑Security Guide) 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.

    Kdump

    Kdump saves the memory image (core dump) to the file system in case the kernel crashes. This enables you to find the cause of the crash by debugging the dump file. Kdump is preconfigured and enabled by default. See Section 17.7, Basic Kdump Configuration, (↑System Analysis and Tuning Guide) for more information.

    Default Systemd Target and Services

    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 6.15.8, System Information, (↑Deployment Guide) for more information.

  13. 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.

  14. During the installation, the progress is shown in detail on the Details tab.

  15. 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 Section 5.0, YaST in Text Mode, (↑Administration Guide) for information on using YaST from a terminal.
