一、环境准备
部署好系统,并准备好工具和文件
bash
# 安装软件,创建目录
dnf install xorriso vim -y
mkdir -p /opt/openEuler/
# 将镜像文件 openEuler-24.03-LTS-x86_64-dvd.iso 上传到 /opt 目录下,并解压到指定目录
# 直接用挂载 iso 文件的方式没有试过,效果应该是一样的
xorriso -osirrox on -indev /opt/openEuler-24.03-LTS-x86_64-dvd.iso -extract / /opt/openEuler/
# 复制并编辑 ks.cfg
cp anaconda-ks.cfg /opt/openEuler/isolinux/ks.cfg
二、编辑 ks.cfg 文件
以下是参考文件,各配置项的详细解释可参考官方文档:Red Hat Enterprise Linux | 7 | Red Hat Documentation
bash
# Generated by Anaconda 36.16.5
# Generated by pykickstart v3.48
#version=DEVEL
# Use graphical install

# Use CDROM installation media

%end
# Run the Setup Agent on first boot

autopart --type=lvm
# Partition clearing information

# Reboot after installation

# Root password

%post
sed -i "s/ ro / ro crashkernel=1024M,high /" /boot/efi/EFI/openEuler/grub.cfg
%end
三、修改启动引导文件
- BIOS 启动文件,只展示需要修改的部分
bash
# chmod +w/opt/openEuler/isolinux/isolinux.cfg
#vim /opt/openEuler/isolinux/isolinux.cfg
label linux
menu label ^Install openEuler 24.03-LTS
menu default
kernel vmlinuz
append initrd=initrd.img inst.ks=cdrom:/isolinux/ks.cfg
label check
menu label Test this ^media & install openEuler 24.03-LTS
# menu default
kernel vmlinuz
append initrd=initrd.img inst.stage2=hd:LABEL=openEuler-24.03-LTS-x86_64 rd.live.check quiet fpi_to_tail=off
menu separator # insert an empty line
- EFI 启动文件,只展示需要修改的部分
bash
# chmod +w /opt/openEuler/EFI/BOOT/grub.cfg
# vim /opt/openEuler/EFI/BOOT/grub.cfg
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Install openEuler 24.03-LTS' --class openEuler --class gnu-linux --class gnu --class os {
linuxefi /images/pxeboot/vmlinuz inst.ks=cdrom:/isolinux/ks.cfg
initrdefi /images/pxeboot/initrd.img
}
menuentry 'Test this media & install openEuler 24.03-LTS' --class openEuler --class gnu-linux --class gnu --class os {
linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=openEuler-24.03-LTS-x86_64 rd.live.check fpi_to_tail=off
initrdefi /images/pxeboot/initrd.img
}
四、生成镜像文件
bash
cd /opt/openEuler/
# 以下命令中一些参数不是必须的,具体可自行测试
xorriso -as mkisofs -o /opt/openEuler.iso \
-V 'openEuler' \
-partition_cyl_align off \
-partition_offset 0 \
--mbr-force-bootable \
--gpt-iso-not-ro \
-iso_mbr_part_type 0x00 \
-c '/isolinux/boot.cat' \
-b '/isolinux/isolinux.bin' \
-no-emul-boot \
-boot-load-size 4 \
-boot-info-table \
-eltorito-alt-boot \
-e '/images/efiboot.img' \
-no-emul-boot \
-boot-load-size 14064 \
-isohybrid-gpt-basdat \
-R -J -v -T ./
