如何使用ubuntu搭建一个无盘PC启动服务器

启动windows,

1. 安装tftp服务器

   sudo apt install tftpd-hpa

2. 设置tftp,sudo systemctl restart tftpd-hpa

   sudo nano /etc/default/tftpd-hpa

   /etc/default/tftpd-hpa

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

3. 安装dhcp服务器

   sudo apt install isc-dhcp-server

4. 设置dhcp服务器的工作网卡

   sudo nano /etc/default/isc-dhcp-server

   Defaults for isc-dhcp-server (sourced by /etc/init.d/isc-dhcp-server)

   Path to dhcpd's config file (default: /etc/dhcp/dhcpd.conf).

   #DHCPDv4_CONF=/etc/dhcp/dhcpd.conf
   #DHCPDv6_CONF=/etc/dhcp/dhcpd6.conf

   Path to dhcpd's PID file (default: /var/run/dhcpd.pid).

   #DHCPDv4_PID=/var/run/dhcpd.pid
   #DHCPDv6_PID=/var/run/dhcpd6.pid

   Additional options to start dhcpd with.

   Don't use options -cf or -pf here; use DHCPD_CONF/ DHCPD_PID instead

   #OPTIONS=""

   On what interfaces should the DHCP server (dhcpd) serve DHCP requests?

   Separate multiple interfaces with spaces, e.g. "eth0 eth1".

   INTERFACESv4="ens34"
   INTERFACESv6=""

5. 设置dhcp的工作网段,sudo systemctl restart isc-dhcp-server

   sudo vi /etc/dhcp/dhcpd.conf

   Global parameter options for the PXE network environment

   default-lease-time 600;
   max-lease-time 7200;
   authoritative;

   Log DHCP actions to the system log (/var/log/syslog)

   log-facility local7;

   Subnet profile bound strictly to the 10.10.1.0/24 infrastructure

   subnet 10.10.1.0 netmask 255.255.255.0 {
   range 10.10.1.10 10.10.1.50; # IP pool reserved for PXE clients
   option subnet-mask 255.255.255.0;
   option broadcast-address 10.10.1.255;

   Point clients directly to your Ubuntu TFTP service configuration

   next-server 10.10.1.100; # Server IP hosting your TFTP files
   filename "undionly.kpxe"; # Network boot loader payload filename
   }

6. 安装isci targetcli-fb

   sudo apt update
   sudo apt install -y targetcli-fb

7. 创建一个磁盘文件

   sudo mkdir -p /var/iscsi_disks

8. 配置iscsi

   1. Register the image file into the LIO backend allocator

   /backstores/fileio create name=disk01 file_or_dev=/var/iscsi_disks/disk01.img size=6G

   2. Create your Unique iSCSI Target Name (IQN)

   /iscsi create iqn.2026-05.ubuntu.storage:target01

   3. Create a Logical Unit Number (LUN) mapping the storage block to your IQN

   cd /iscsi/iqn.2026-05.ubuntu.storage:target01/tpg1/luns
   create /backstores/fileio/disk01

   4. Define which client is allowed to connect (ACL)

   For testing, map it to the standard iPXE initiator name

   cd ../acls
   create iqn.2010-04.org.ipxe:initiator

   cd /iscsi/iqn.2026-05.ubuntu.storage:target01/tpg1

   Permit any initiator to connect without an explicit ACL entry

   set attribute generate_node_acls=1

   Allow write operations for these dynamically created client nodes

   set attribute cache_dynamic_acls=1

   Turn off explicit CHAP (username/password) validation mechanisms

   set attribute authentication=0

   set attribute demo_mode_write_protect=0

   cd /
   saveconfig
   exit

9. 打开防火墙,启动服务

   sudo ufw allow to any port 3260 proto tcp
   sudo systemctl enable target
   sudo systemctl restart target
   sudo systemctl status target

10. 编写ipxe脚本,boot.ipxe

    #!ipxe
    dhcp
    sanboot iscsi:10.10.1.100::::iqn.2026-05.ubuntu.storage:target01

11. 下载的编译ipxe

    git clone https://github.com/ipxe/ipxe.git
    cd ipxe/src
    sudo apt install gcc
    sudo apt install make
    sudo apt install liblzma-dev
    make bin-x86_64-pcbios/undionly.kpxe EMBED=boot.ipxe
    cp bin-x86_64-pcbios/undionly.kpxe /srv/tftp

12. 在同一个网段启动目标pc， 先使用sanhook和winpe进入系统，分区

    DISKPART> list disk
    DISKPART> select disk [Your iSCSI Disk Number]
    DISKPART> clean
    DISKPART> convert mbr
    DISKPART> create partition primary
    DISKPART> select partition 1
    DISKPART> active
    DISKPART> format quick fs=ntfs label="WinPE_BIOS"
    DISKPART> assign letter=C
    DISKPART> exit

13. 安装系统到 C:

    dism /Apply-Image /ImageFile:Z:\path\to\boot.wim /Index:1 /ApplyDir:C:\

14. 安装bootloader

    bcdboot C:\Windows /s C: /f BIOS

15. 修改注册表msiscsi的设置

    reg load HKLM\TARGET_SYSTEM C:\Windows\System32\config\SYSTEM
    reg add HKLM\TARGET_SYSTEM\ControlSet001\Services\Ndis /v Start /t REG_DWORD /d 0 /f
    reg add HKLM\TARGET_SYSTEM\ControlSet001\Services\msiscsi /v Start /t REG_DWORD /d 0 /f
    reg add HKLM\TARGET_SYSTEM\Setup /v "SystemSetupInProgress" /t REG_DWORD /d 1 /f
    reg unload HKLM\TARGET_SYSTEM

16. 禁用早段网络

    reg load HKLM\TARGET_SYSTEM C:\Windows\System32\config\SYSTEM

    :: Add the override parameter to skip standard initialization
    reg add HKLM\TARGET_SYSTEM\Setup /v "DisableWpeinitNetwork" /t REG_DWORD /d 1 /f

    :: Disable the NDIS lightweight filter driver execution path
    reg add HKLM\TARGET_SYSTEM\ControlSet001\Services\NdisWdf /v Start /t REG_DWORD /d 4 /f

    reg unload HKLM\TARGET_SYSTEM

17. 修改使用ipxe.pxe作为bootfile

    make bin-x86_64-pcbios/ipxe.pxe EMBED=boot.ipxe
    cp bin-x86_64-pcbios/ipxe.pxe /srv/tftp

    #make bin-x86_64-pcbios/undionly.kpxe EMBED=boot.ipxe
    #cp bin-x86_64-pcbios/undionly.kpxe /srv/tftp

18. 修改boot.ipex

    #!ipxe

    dhcp
    set keep-san 1
    set net0.dhcp/gateway 0.0.0.0
    sanboot --keep iscsi:10.10.1.100::::iqn.2026-05.ubuntu.storage:target01
