一、tftp服务搭建

服务器选用Debian12，安装tftpd-hpa服务，配置文件如下：

sudo apt install tftpd-hpa

user@DNS$ cat /etc/default/tftpd-hpa 

# /etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/tftp"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure"

二、配置uefi模式的pxe启动文件

选择合适的netboot程序，这里选用Debian的netboot

wget https://mirrors.ustc.edu.cn/debian/dists/stable/main/installer-amd64/current/images/netboot/netboot.tar.gz

解压到tftp的根目录内，然后修改tftp目录下的配置文件，下面直接贴出各系统的自动安装配置

uefi模式添加默认本地硬盘启动，以下配置需手动添加到tftp目录下的debian-installer/amd64/grub/grub.cfg 中

set timeout=5
set default=0
menuentry 'Boot from next volume' {
        exit 1
}

添加Debian12网络启动，并添加了自动化安装脚本：

menuentry 'Install Debian' {
	linux    debian-installer/amd64/linux auto=true priority=critical vga=788 auto locale=zh_CN url=http://dns.a.v/preseed.cfg
        initrd   debian-installer/amd64/initrd.gz
}

openEuler的网络安装配置，同样添加了ks.cfg自动安装脚本：

menuentry 'openEuler 24.03 LTS SP2' --class openEuler --class gnu-linux --class gnu --class os {
        linuxefi openEuler/vmlinuz ip=dhcp inst.ks=http://dns.a.v/ks.cfg inst.repo=http://mirrors.tuna.tsinghua.edu.cn/openeuler/openEuler-24.03-LTS-SP2/OS/x86_64
        initrdefi openEuler/initrd.img
}
menuentry 'Kylin Server V10 SP3' --class red --class gnulinux --class gnu --class os {
    linux Kylin/vmlinuz ro inst.geoloc=0 console=ttyAMA0 console=tty0 rd.iscsi.waitnet=0 ip=dhcp inst.repo=http://dns.a.v/Kylin-V10-SP3 inst.ks=http://dns.a.v/ksKylin.cfg
    initrd Kylin/initrd.img
}
menuentry 'UOS Server v20 1070a' {
        linuxefi uos/vmlinuz ip=dhcp inst.ks=http://dns.a.v/ksuos.cfg
        initrdefi uos/initrd.img
}

Ubuntu的网络安装配置，并配置了自动安装脚本：

menuentry 'ubuntu server 26.04.1 lts' {
        linux   ubuntu/vmlinuz root=/dev/ram0 ramdisk_size=1500000 ip=dhcp iso-url=http://dns.a.v/ubuntu-26.04.1-live-server-amd64.iso autoinstall ds=nocloud-net\;s=http://dns.a.v/autoinstall ---
        initrd  ubuntu/initrd
}

三、添加传统bios模式的启动配置

以下这个参数添加入tftp目录的/home/tftp/menu.cfg

menu hshift 4
menu width 70

menu title GNU/Linux installer menu (BIOS mode)
include debian-installer/amd64/boot-screens/stdmenu.cfg

label Alpine
	menu label ^Alpine Linux
        linux alpine/vmlinuz-lts ip=dhcp modloop=http://dns.a.v/modloop-lts alpine_repo=http://mirrors.ustc.edu.cn/alpine/latest-stable/main
        initrd alpine/initramfs-lts

label Debian Server
	menu label ^Debian Server 
        linux    debian-installer/amd64/linux preseed/url=http://dns.a.v/preseed.cfg auto=true priority=critical vga=788 locale=zh_CN interface=auto hostname=DB2026 domain=
        initrd   debian-installer/amd64/initrd.gz

label Ubuntu Server
	menu label ^Ubuntu Server 26.04.1 lts
	kernel ubuntu/vmlinuz
	initrd ubuntu/initrd
#	append url=http://dns.a.v/ubuntu/ ip=dhcp root=/dev/ram0 ramdisk_size=2500000 iso-url=http://dns.a.v/ubuntu-24.04.4-live-server-amd64.iso autoinstall ds=nocloud-net;s=http://dns.a.v/autoinstall/ ---
	append iso-url=http://dns.a.v/ubuntu-26.04.1-live-server-amd64.iso ip=dhcp root=/dev/ram0 ramdisk_size=2500000 autoinstall ds=nocloud-net;s=http://dns.a.v/autoinstall/ ---

#label Kylin Server
#        menu label ^Kylin Server V10 SP3
#        linux Kylin/vmlinuz ro inst.geoloc=0 console=ttyAMA0 console=tty0 rd.iscsi.waitnet=0 ip=dhcp inst.repo=http://dns.a.v/Kylin-V10-SP3 inst.ks=http://dns.a.v/ksKylin.cfg
#        initrd Kylin/initrd.img

#label openEuler Server
#        menu label ^openEuler-24.03-LTS-SP2
#        linuxefi openEuler/vmlinuz ip=dhcp inst.ks=http://dns.a.v/ks.cfg inst.repo=http://mirrors.tuna.tsinghua.edu.cn/openeuler/openEuler-24.03-LTS-SP2/OS/x86_64
#        initrdefi openEuler/initrd.img

#label UOS Server
#        menu label UOS Server v20 1070a
#        linuxefi uos/vmlinuz ip=dhcp inst.ks=http://dns.a.v/ksuos.cfg
#        initrdefi uos/initrd.img

timeout 100

label local
	menu label ^Boot from local drive
	localboot 0
	menu default

五、dhcp配置

如果是跨vlan的不同网段网络启动安装Linux需要做如下设置，以华为网络设备为例

uefi启动模式：

 dhcp server next-server 192.168.50.5
 dhcp server bootfile debian-installer/amd64/bootnetx64.efi

bios启动模式

 dhcp server next-server 192.168.50.5
 dhcp server bootfile pxelinux.0

六、更新操作

dns:~# cat /home/tftp/new.sh 
curl -L http://mirrors.nyist.edu.cn/debian/dists/stable/main/installer-amd64/current/images/netboot/netboot.tar.gz -o /home/tftp/netboot.tar.gz
curl -L https://mirrors.ustc.edu.cn/alpine/latest-stable/releases/x86_64/netboot/initramfs-lts -o /home/tftp/alpine/initramfs-lts
curl -L https://mirrors.ustc.edu.cn/alpine/latest-stable/releases/x86_64/netboot/vmlinuz-lts -o /home/tftp/alpine/vmlinuz-lts
curl -L https://mirrors.ustc.edu.cn/alpine/latest-stable/releases/x86_64/netboot/modloop-lts -o /home/share/modloop-lts
chown nobody -R /home/tftp
tar zxf /home/tftp/netboot.tar.gz -C /home/tftp
cd /home/tftp/debian-installer/amd64/boot-screens/
ln -sfn ../../../menu.cfg ./
cd /home/tftp/debian-installer/amd64/grub/
ln -sfn ../../../grub.cfg ./
