How to automate installation and configuration on Kirin operating system?

Kirin operating system is a powerful operating system independently developed in China and is widely used in various fields. Manual installation and configuration of the system is a tedious and time-consuming task when deploying on a large scale or when frequent system reinstallation is required. Therefore, understanding how to automate installation and configuration on Kirin OS will greatly improve efficiency and convenience. This article will detail how to automate installation and configuration by using Kickstart tools and Shell scripts.

1. Preparations before installation
Before starting the automated installation, you first need to prepare the following tools:

1. Kirin operating system CD or ISO image file.
2. The target computer where the system is installed.
3. An available computer is used as the installation server, and services such as HTTP, FTP or NFS need to be set up.

2. Use the Kickstart tool to create a configuration file
Kickstart is an automated installation tool that can achieve unattended installation by providing a configuration file. The following is the contents of an example Kickstart configuration file:

platform=x86, AMD64, or Intel EM64T

version=DEVEL

auth --useshadow --enablemd5
network --bootproto=dhcp --device=eth0
timezone --utc Asia/Shanghai
rootpw --iscrypted $1$5xg03e3$6XK5tvPx6VMz2U8wjroqV.
firewall --disabled
selinux --disabled
reboot

Install OS instead of upgrade

install
cdrom

Use graphical installation

graphical
lang en_US.UTF-8
keyboard us
skipx

Use NFS installation media

nfs --server=192.168.1.100 --dir=/path/to/installation/files

Network information

network --bootproto=dhcp --hostname=myserver.example.com

Partition information

part /boot --fstype=ext4 --size=200 --asprimary
part pv.008001 --size=1 --grow

volgroup vg_myserver pv.008001
logvol swap --fstype=swap --name=lv_swap --vgname=vg_myserver - -size=2048 --grow --maxsize=8192
logvol / --fstype=ext4 --name=lv_root --vgname=vg_myserver --size=10240 --grow

%packages
@base
@core
kexec-tools

%post
rm -rf /etc/yum.repos.d/*
echo "[BaseOS]" >> ; /etc/yum.repos.d/baseos.repo
echo "name=BaseOS" >> /etc/yum.repos.d/baseos.repo
echo "baseurl=http://192.168 .1.100/repo/BaseOS" >> /etc/yum.repos.d/baseos.repo
echo "enabled=1" >> /etc/yum.repos.d/baseos.repo
echo "gpgcheck=0" >> /etc/yum.repos.d/baseos.repo
echo "[AppStream]" >> /etc/yum.repos.d/appstream.repo
echo "name=AppStream" >> /etc/yum.repos.d/appstream.repo
echo "baseurl=http://192.168.1.100/repo/AppStream" >> /etc/yum .repos.d/appstream.repo
echo "enabled=1" >> /etc/yum.repos.d/appstream.repo
echo "gpgcheck=0" >> /etc/yum .repos.d/appstream.repo
dnf install -y httpd
systemctl start httpd
systemctl enable httpd
mkdir -p /var/www/html/repo/BaseOS
mkdir -p /var/www/html/repo/AppStream

%end

In the above configuration file, you can set various parameters of the system, such as authentication method, network settings, installation source, partition information, etc. . Can be configured according to actual needs.

3. Configure the installation server
Insert the Kylin operating system CD into the installation server and mount the CD to a suitable directory, such as the /mnt directory. Enter the isolinux directory of the CD and copy the initrd.img and vmlinuz files to the appropriate directory, such as the /var/www/html directory. Copy all files on the Kirin operating system CD to a suitable directory, such as /var/www/html/repo.

4. Start the installation
On the target computer, boot it to the network boot through BIOS settings. During the startup process, press the Tab key and keep the cursor at the boot: prompt. Here, enter the following command to start the automated installation:

linux ks=http://192.168.1.100/ks.cfg

Among them, ks.cfg is the Kickstart configuration file created previously path. Change the IP address yourself as needed.

5. Configuration process
According to the settings of the Kickstart configuration file, Kirin operating system will be installed according to the pre-configured options. During the installation process, partitioning, software package selection, network configuration, etc. will be automatically performed. Using Kickstart to automate your installation can significantly save time and effort.

6. Automated configuration
In the %post section of the Kickstart configuration file, you can add a Shell script to perform some customized configurations. For example, you can configure the IP address of the installation server as the system's yum source, set up the Apache HTTP server, and create the necessary directories and files. The %post part of the above Kickstart configuration file is an example and can be modified according to actual needs.

Summary:
Automated installation and configuration is very useful in large-scale deployment or frequent system reinstallation, which can greatly improve efficiency and convenience. Through Kickstart tools and Shell scripts, automated installation and configuration can be easily realized on Kirin operating system. We hope that the introduction and examples provided in this article can help readers understand and use these tools and better apply them in practical work.
