pending on the hardware, even the firmware or BIOS of the computer may already be
accessible to the serial console. If this is possible, you can carry out the entire installation
using this method. To activate the serial console installation, additionally specify the
parameter
console=ttyS0
at the boot prompt directly after the boot process has
completed and before the installation system starts.
On most computers, there are two serial interfaces, ttyS0 and ttyS1. For the installation,
you need a terminal program like minicom or screen. To initiate the serial connection,
launch the screen program in a local console by entering the following command:
screen /dev/ttyS0 9600
This means that screen listens to the first serial port with a baud rate of 9600. From this
point on, the installation proceeds similarly to the text-based installation over this ter-
minal.
2.3 Installation with SSH
If you do not have direct access to the computer hardware and, for example, the instal-
lation should be launched from a management console, control the entire installation
process over the network. To do this, enter the parameters
UseSSH=1
and
SSHPassword=<secret>
at the boot prompt. An SSH daemon is then launched in
the system and you can log in to the system as user
root
with the password “secret”.
To connect, use the command
ssh -X root@<ipaddr>
.
If you do not have a DHCP server available in your local network, manually assign an
IP address to the installation system. Do this by entering the option
HostIP=<ipaddr>
at the boot prompt.
As soon as you are logged in to the installation system, launch the actual installation
with the command
yast
for a text-based installation or
yast2
to proceed with the
graphical installation. This then guides you through the installation. This procedure is
described in detail in Section 4.1.5, “Simple Remote Installation via SSH—Dynamic
Network Configuration” (Chapter 4, Remote Installation, ↑Installation and Administra-
tion).
