踩雷

deepin 安装包 中 的 grubx64.efi 无法 nas 网络启动 更换为 openouler 中的 grubx64.efi 即可 网络启动

dhcpd 和 dnsmasq 区别

dhcpd 比较 专业 配置 较多， 但是 只提供了 dhcp 服务， 想要 域名服务 还需要 bind9 来 支持

dnsmasq 业余一点， 但是 同时 提供了 dhcp 以及 域名 解析的 功能 用来 装机 还是 不错的 address=/example.com/ is equivalent to --server=/example.com/

搭建 server

docker run  -dit  --privileged=true  --name ubuntu-pxe  docker-hub.one-k.xyz/ubuntu:20-04  bash
# ps -aux
# USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
# root           1  0.0  0.0   1104     4 pts/0    Ss   11:10   0:00 /bin/bash
# root           7  0.0  0.0   4240  3468 pts/0    S+   11:10   0:00 bash

# 进入 容器
docker exec -it ubuntu-pxe  bash 

apt update 
apt install  dnsmasq  -y
apt install vim  -y
apt-get install --reinstall systemd

service dnsmasq restart


docker run  -dit  --privileged=true  --init  --name ubuntu-pxe  docker-hub.one-k.xyz/ubuntu:pxe  bash
# ps -aux
# USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
# root           1  0.0  0.0   1104     4 pts/0    Ss   11:10   0:00 /sbin/docker-init -- bash
# root           7  0.0  0.0   4240  3468 pts/0    S+   11:10   0:00 bash

Well, this is embarrassing:

My system is using EFI and the setup described in the linked article is about legacy BIOS systems.

After swapping the boot path with the correct one (EFI/boot/bootx64.efi) I get readable error messages that I can google.
