Installing from Internet
When everything is set up correctly, you can start the installation. The installation retrieves the installation data from the fastest mirror for you. It then proceeds as described in DVD installation, step 1 with the exception of the network configuration step needed prior to adding additional repositories. This step is not needed as the network is already configured and active at this point.
Installing from another local network sources
- Boot the system and wait for the boot screen to appear.
[F2]to choose the language and your keyboard layout.
[F3]to choose the screen resolution.
[F4]and select the desired network protocol (SLP, FTP, HTTP, NFS and SMB/CIFS are supported).
- Provide the server's address and the path to the installation media:
- Select Installation from the main boot menu and
[Enter]enter to continue.
- The installation program automatically configures the network connection with DHCP. If this configuration fails, you are prompted to enter the appropriate parameters manually.
- The installation retrieves the installation data from the source specified.
- The installation then proceeds as described in the step-by-step installation guide with the exception of the network configuration step needed prior to adding additional repositories. This step is not needed as the network is already configured and active at this point.
Media free network installation
No reliable CD/DVD writer around? Out of CDs or just too lazy to download and burn the whole installation image?
There is a quick way with only one important limitation, use it only to add another installation to your computer. If network installation is interrupted for any possible reason, you need your current system to restart installation.
The idea is to boot the system using kernel and initd images published on the Internet or in your network repository. Below is the example with 42.2 repositories of openSUSE.
You have to be root user for this.
Get the kernel and initrd images
mkdir /boot/install cd /boot/install wget http://download.opensuse.org/distribution/leap/42.2/repo/oss/boot/$(uname -i)/loader/linux wget http://download.opensuse.org/distribution/leap/42.2/repo/oss/boot/$(uname -i)/loader/initrd
No need to replace $(uname -i) as the command shell will replace it with your current architecture.
title install root (sdX,Y) # change this (sdX,Y) kernel /boot/install/oS-42.2.vmlinuz.install install=http://download.opensuse.org/distribution/openSUSE-stable/repo/oss/ initrd /boot/install/oS-42.2.initrd.install
Change (sdX,Y) to whatever your setup requires, e.g. to partition that is used in the previous entries to download installation files.
There are two ways to start installation:
- Reboot computer and choose "install" option on the grub boot screen. This works only if you edited GRUB as explained above.
- Use the kernel's bootloader emulation 'kexec' and skip the hardware reboot. Make sure that package named kexec-tools is installed. Then:
kexec -l /boot/install/oS-42.2.vmlinuz.install --initrd=/boot/install/oS-42.2.initrd.install kexec -e
First command will load installation kernel and initrd in a memory, and second will start new kernel.
Moment after 'kexec -e' you will see a boot message of the installation kernel.
