IPXE网络引导通过kickstart和preseed自动安装centos/ubuntu/debian系统

发布时间:September 28, 2018 // 分类: // No Comments

编译ipxe,也可从netboot.xyz下载编译好的,netboot默认包含一些常用系统的安装规则。

git clone git://git.ipxe.org/ipxe.git
cd ipxe/src
sed -i -e '/DOWNLOAD_PROTO_HTTPS/ s/#undef/#define/' config/general.h
sed -i -e '/define IMAGE_TRUST_CMD/ s/\/\///' config/general.h
sed -i -e '/define IPSTAT/ s/\/\///' config/general.h
make bin/ipxe.lkrn

加入grub引导项,set root为boot目录所在分区,/ipxe.lkrn为文件相对于boot所在分区的绝对路径,如果boot为单独分区刚为/ipxe.lkrn,非单独分区为/boot/ipxe.lkrn,hd0为第一个硬盘,msdos1为第一个mbr分区,如果是gpt使用gpt1。

cat >> /etc/grub.d/40_custom <<EOF
menuentry 'ipxe boot' {
    set root='hd0,msdos1'
    linux16 /ipxe.lkrn
    initrd16 /ipxe.initrd
}
EOF
sed -i 's/GRUB_DEFAULT=.*/GRUB_DEFAULT="ipxe boot"/' /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg 

调用ipxe规则的几种方法:
1.grub引导参数和HTTP调用远程文件:

#ipxe启动后dhcp获取IP然后获取netboot规则。
linux16 /ipxe.lkrn dhcp && chain --autofree https://boot.netboot.xyz

2.本地文件ipxe.initrd:

#!ipxe
imgfree
set net0/ip 192.168.168.4
set net0/netmask 255.255.255.0
set net0/gateway 192.168.168.1
set dns 192.168.168.1
ifopen net0
chain --autofree https://boot.netboot.xyz

3.编译时也可将规则嵌入进去:

make bin/ipxe.lkrn EMBED=boot.ipxe

注:Centos7安装内存不得小于2G,可不使用ipxe直接下载centos/ubuntu网络安装文件到本地添加到grub自动安装,使用ipxe方便管理。
