预置 debian 11 完全无人值守（摆脱问题）

  • 772

我正在尝试完全自动化地预置 debian 11 netinstall。我在这里阅读了许多文档：

这是我的引导行（来自 grub.cfg）

set default="autoinstall"
set timeout=3

menuentry "Debian 11 Fully Automated UEFI LVM LUKS BTRFS Remote Decrypt DEBUG TTY4" --id autoinstall {
        set background_color=black
        linux    /debian-installer/amd64/linux auto=true url=tftp://192.168.1.100/preseed/debseed11_crypt.cfg net.ifnames=0 biosdevname=0 ipv6.disable=1 language=en locale=en_US.UTF-8 keymap=fr vga=788 noprompt DEBCONF_DEBUG=5 --- quiet
        initrd   /debian-installer/amd64/initrd.gz
}

这是我的预置文件：

目前我得到 debien 安装程序要求我：

  • 主机名
  • 域名

我只是想摆脱这些问题。这是我尝试过的：

  • 我尝试在 pxe 服务器上的命令行内核选项中使用 priority=critical。
  • 我将我的 dhcpd 服务器配置为管理此特定主机的主机名域名。
host curiosity {
hardware ethernet 12:34:45:12:34:56;
fixed-address 192.168.1.90;
option host-name "curiosity";
option domain-name "planet.mars";
}

我知道我可以设置主机名/域变量，一切都会好起来的，但我想制作一个非常通用的预置来部署在多个服务器上。

一些帮助或线索将不胜感激。

提前谢谢你。

顺便说一句，第一个 preseed 并不完美。如果有人对此感兴趣，那就更好了。

    我找到了一种方法！感谢这篇关于相反问题的帖子

    我刚刚在 grub.cfg 的引导行中添加了两个参数

    netcfg/get_hostname=install netcfg/get_domain=install

    它现在是完全自动化的，不问任何问题。
