[系统运维]国产麒麟系统PXE安装-UEFI引导

注意：

• 适用uefi引导

• 适用x86_64架构

  一键部署脚本扣我

1.上传ISO到PXE服务器，拷贝ISO文件

mkdir /kylin_iso
mount -o loop Kylin-Server-10-SP1-Release-Build04-20200711-x86_64.iso /kylin_iso/

2.配置http，获取安装源

yum -y install httpd
mkdir /var/www/html/{ks,kylin}
# 注意一定是"/kylin_iso/",两边的斜杠都要有
rsync -a /kylin_iso/ /var/www/html/kylin/
chmod -R 755 /var/www/html/kylin

3.配置dhcp，获取ip

yum -y install dhcp
cat >/etc/dhcp/dhcpd.conf <<-EOF
ddns-update-style interim;
ignore client-updates;
#此filename文件在EFI/BOOT下
filename "grubx64.efi";
next-server 172.28.28.20;

subnet 172.28.28.0 netmask 255.255.255.0 {
	option routers 172.28.28.254;
	option subnet-mask 255.255.255.0;
	range dynamic-bootp 172.28.28.30 172.28.28.60;
	default-lease-time 21600;
	max-lease-time 43200;
}
EOF

4.配置tftp，获取引导文件

4.1安装tftp，拷贝文件

yum -y install tftp tftp-server xinetd
# 修改/etc/xinetd.d/tftp文件，将disable=yes改为disable=no
rm -rf /var/lib/tftpboot/*
cp -rf /kylin_iso/images/pxeboot/* /var/lib/tftpboot/
cp -f /kylin_iso/EFI/BOOT/grub*.efi /var/lib/tftpboot

4.2编写grub.cfg文件

拷贝镜像文件中的EFI/BOOT/grub.cfg文件修改也行，自己写也行

cat > /var/lib/tftpboot/grub.cfg << -EOF
set default="0"
function load_video {
        if [ x$feature_all_video_module = xy ]; then
                insmod all_video
        else
                insmod efi_gop
                insmod efi_uga
                insmod ieee1275_fb
                insmod vbe
                insmod vga
                insmod video_bochs
                insmod video_cirrus
        fi
}

load_video
set gfxpayload=keep
insmod gzio
insmod part_gpt
insmod ext2

set timeout=10

### BEGIN /etc/grub.d/10_linux ###

        initrd /initrd.img
}

5.配置kickstart文件

# 编写root加密密码脚本
cat > /tmp/rootpw.py <<-EOF
		#!/usr/bin/python2
		import crypt
		print(crypt.crypt("qwer1234!@#$"))
EOF
# python2 /tmp/rootpw.py | sed 's/\$/\\\$/g' | sed 's/.$//'
# 将下边这一串复制，在kickstart文件里用

6.启动各服务

systemctl start httpd
systemctl start dhcpd
systemctl start tftp
systemctl start xinetd
