If you want to enable passwordless authentication over the SSH connection, you can import a key using the Import SSH public key. If you want to completely disable root login using a password, download a single key and do not specify a root password. In this case, a connection as a system administrator is only possible via SSH with the respective key. The changes you can make here can also be made later at any time from the installed system. However, if you need remote access right after installation, you will need to adjust the security settings. Follow these instructions if you do not have a Linux system on your computer or if you want to replace an existing Linux system. A minimum of 512 MB of memory is required to install nfs, FTP, and SMB installation sources, or when using VNC. Note that storage requirements also depend on the number of devices visible to the z/VM guest or LPAR image. Installation with many accessible devices (even if they are not used for installation) may require more memory. If you are on an Ubuntu/Debian-based system, you can install etcher by running the following commands: Enter a password for the system administrator account (called root user). This step is skipped if you selected Use this password for the system administrator in the previous step.
If you don`t have an internet connection, don`t worry. Continue with the installation process and update your system later when you are done. Once the installation is complete, restart your PC. You will see the openSUSE boot menu, which gives you an option to boot the system. You can see the different options in the screenshot below. If you do not know what to choose, select the first option – “openSUSE Leap 15.2”. Press Enter when you`re done. This will load the openSUSE 15.2 desktop as shown in the screenshot below. Please note that if you have selected a desktop environment other than GNOME, your system may look slightly different from mine.
For more information about installing the AArch64 and POWER variants, see en.opensuse.org/Portal:ARM and en.opensuse.org/Portal:PowerPC. Select the clock and time zone to use in your system. To manually set the time or configure an NTP server for time synchronization, select More Settings. See Section 3.8, “Clock and Time Zone” for more information. Skip to Next. On the next screen, enter the username and passwords you want for your local account. You can enable the “Use this password for the system administrator” option and disable the “Automatic login” option. Click Next to continue. Select the desktop system you want 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. XFCE Desktop and LXDE Desktop are fast and lightweight desktop environments suitable for modest hardware.
With Minimal X Window, install a graphics window manager that allows standalone X applications and console windows to run, but does not provide the usual built-in desktop features. In the minimum server selection (text mode), only console terminals are available. The maximum number of processors supported by the software design is 8192 for Intel 64 and AMD64. If you intend to use such a large system, search for supported devices on our hardware systems certification website, see www.suse.com/yessearch/. Different installation methods have different storage requirements during installation. For text-mode installation on z/VM, LPAR, and KVM, at least 1 GB of memory is recommended. Installation in graphical mode requires at least 1.5 GB of memory. Note: Storage requirements for remote installation sources Disk requirements depend largely on the installation you selected and the use of your computer. In general, you need more disk space than the installation software itself needs to have a system that works properly. The minimum system requirements for different choices are as follows: disk space depends on your channel`s system requirements, at least 100 GB Disk requirements depend on the type of installation you choose and the usage scenario. Usually, a system that works properly takes up more space than the installation itself. The minimum requirements are as follows.
After downloading the openSUSE dvd ISO file, we need to create a bootable USB drive to install the operating system of our PC. We will use a popular tool called Etcher. We already have a tutorial on how to create a live Linux USB drive with etcher available on our website. It gives you a complete guide on how to install and use Etcher on different Linux distributions. Select Download Repository Description Files to download the files that describe the repository now. If they are disabled, they will be downloaded after starting the installation. Proceed to Next and insert media if necessary. Depending on the content of the product, it may be necessary to accept additional license agreements. Skip to Next.
Add-on products can also be installed at any time later by the running system, as described in Chapter 10, Installing Add-on Products. Once the kernel is loaded, the installation window opens. To begin with, Setup performs a few checks, including a network connection test. If your system has an active Internet connection, it will attempt to add online repositories that are required to download updates for your new system. By default, the system boots to the graphics target with support for network, multi-user, and display manager. Switch to Multi-User if you don`t need to log in using the Display Manager. In the next window, you need to select the system role. If you want to use OpenSUSE as your desktop system, you must select a desktop environment from those listed below. These include KDE Plasma, GNOME and Generic Desktop. If you want to use it as a server, you can choose between the Server and Transaction Server options.
In our case, we select the GNOME desktop environment. Click Next when you`re done. A minimum of 1024 MB of memory is required for a Server Core installation. On computers with more than two processors, add 512 MB per processor. For remote installations via HTTP or FTP, add an additional 150 MB. Note that these values apply only to operating system installation – actual memory requirements in production depend on the system workload. If you install OpenSUSE on disk as the primary operating system, you can continue with the default system settings as shown below. If you want to use the LVM partitioning scheme, click the Guided Configuration option at the bottom and enable the option for LVM. Once setup has performed the required system checks (which takes little time), you will be presented with a window in which you can select the language and keyboard layout you want to use for your installation process.
You`ll also see the license agreement that you can read – when you`re done, click Next. You can also manually select your system`s software configuration. Select Custom, and then select Next to access the Software Selection and System Tasks dialog box. Select one or more templates to install. You can select individual packages by clicking Details. It is recommended to use only the characters available on an English keyboard. In the event of a system failure or when you need to boot your system into standby mode, a localized keyboard may not be available. In the following steps, you can also add LVM support and disk encryption. You can change the file system of the root partition and decide whether or not to use a separate home partition. A system scan is performed in which Setup searches for storage devices and tries to find other installed systems. When the Analasys is finished, the Installation Options screen starts. Disk requirements are largely dependent on the installation.
For a system to function properly, you usually need more disk space than is required by the installation software. .
