1.update mode

Installing and upgrading the system

2.kickstart mode

Automatic installation.

3.rescue mode

Rescue mode

Stage1:

1. Start the isolinux/initrd.img in the installation media

2. Execute init in initrd.img

Resolves the parameters specified by the boot media.

Check car hardware equipment, load necessary drive

Stage2:

1. Executive Image/stage2.img

Set installation options and plan for installation and update

/root/anaconda-ks.cfg is automatically generated when the system is installed using Anaconda mode, and can be used as a template for kickstart files.

The content consists of 3 parts:

1. Command section:

The settings specified by the command need to be used during installation.

2. Package Selection section:

Start with%packages, specify the packages and package groups that need to be installed in the system installation, and so on.

3. Script Segments

%pre the script that was executed before the system was installed.

%post scripts that are executed after the system is installed

Installation options, commands that you can use in the boot prompt

Linux COMMAND

Askmethod manually select the installation method.

%post scripts that are executed after the system is installed

#ksalidator Ksfile

Check the Kickstart file configuration for errors and need to install the System-config-kickstart package.

#system-config-kickstart graphical editing Kickstart tool.

Example: Creating a very small installation disc

1. Mount the disc

#mount/dev/cdrom/mnt/cdrom

2. Copy the Isolinux images on the disc

#cp-pr/mnt/cdrom/{isolinux,images}/tmp/test/

3. Edit the Isolinux.cfg file

#vim/tmp/test/isolinux/isolinux.cfg

Default Linux Ks=cdrom:/ks.cfg

4. Edit Boot.msg

#vim boot.msg

You can add the information you want to display yourself

5. Create a ks.cfg file

#vim/tmp/test/ks.cfg

6. Create a disc image file

# #mkisofs-R-b/tmp/test/isolinux/isolinux.bin--no-emul-boot-boot-load-size 4-boot-info-table-o Boot.iso/tmp/iso
