Red Hat Summit第13章 Starting Kickstart installations
You can start Kickstart installations in multiple ways:
- Automatically by editing the boot options in network boot configuration.
- Automatically by providing the file on a volume with a specific name.
- Manually by providing inst.ks= kernel command line option in bootloader menu.
You can register RHEL using the Red Hat Content Delivery Network (CDN). CDN is a geographically distributed series of web servers. These servers provide, for example, packages and updates to RHEL hosts with a valid subscription.
During the installation, registering and installing RHEL from the CDN offers following benefits:
- Utilizing the latest packages for an up-to-date system immediately after installation and
- Integrated support for connecting to Red Hat Lightspeed and enabling System Purpose.
13.1. Starting a Kickstart installation automatically by using PXE or UEFI HTTP boot
AMD64, Intel 64, and 64-bit ARM systems and IBM Power Systems servers have the ability to boot by using a PXE server. When you configure the PXE server or UEFI HTTP boot, add the boot option into the boot loader configuration file. It in turn starts the installation automatically. By using this approach, it is possible to automate the installation completely, including the boot process.
This procedure is intended as a general reference; detailed steps differ based on your system’s architecture, and not all options are available on all architectures (for example, you cannot use PXE boot on 64-bit IBM Z).
Prerequisites
- You have a Kickstart file ready in a location accessible from the system to be installed.
- You have a PXE server that can be used to boot the system and begin the installation and/or an HTTP server configured for UEFI HTTP boot.
Procedure
Open the boot loader configuration file on your PXE server, and add the
inst.ks=boot option to the appropriate line. The name of the file and its syntax depends on your system’s architecture and hardware:On AMD64 and Intel 64 systems with BIOS, the file name can be either default or based on your system’s IP address. In this case, add the
inst.ks=option to the append line in the installation entry. A sample append line in the configuration file looks similar to the following:append initrd=initrd.img inst.ks=http://192.168.124.2/kickstarts/ks.cfgOn systems using the GRUB2 boot loader (AMD64, Intel 64, and 64-bit ARM systems with UEFI firmware and IBM Power Systems servers), the file name will be
grub.cfg. In this file, append theinst.ks=option to the kernel line in the installation entry. A sample kernel line in the configuration file will look similar to the following:linuxefi /redhat/images/pxeboot/vmlinuz inst.ks=http://192.168.124.2/kickstarts/ks.cfg
If you want to configure an automated Kickstart installation by using UEFI HTTP boot, locate the bootloader configuration file (grub.cfg) served by the HTTP server and edit it in a similar way as in step 1.b:
linuxefi /redhat/images/pxeboot/vmlinuz inst.ks=http://192.168.124.2/kickstarts/ks.cfgBoot the installation from the network server.
The installation begins now by using the installation options specified in the Kickstart file. If the Kickstart file is valid and contains all required commands, the installation is completely automated.
注記If you have installed a Red Hat Enterprise Linux Beta release, on systems having UEFI Secure Boot enabled, then add the Beta public key to the system’s Machine Owner Key (MOK) list.
