Apache setup log

Nixos

• create bootable usb stick from installer iso

• boot from usb stick

• connect to wifi

• set keyboard layout

• run gparted

• create 512 MB fat32 boot partition /dev/sda1 with an esp and boot flag

• create unformatted partition from rest /dev/sda2

• encrypt and open unformatted partition:

  cryptsetup -y -v luksFormat /dev/sda2
  cryptsetup -v luksOpen /dev/sda2 nixos
  

• create lvm volumes:

  pvcreate /dev/mapper/nixos
  vgcreate nixos /dev/mapper/nixos
  lvcreate -L 16G -n swap nixos
  lvcreate -L 100G -n nix nixos
  lvcreate -L 20G -n root nixos
  lvcreate -L 32G -n docker nixos
  lvcreate -l 100%FREE -n home nixos
  

• format partitions:

  mkswap -L swap /dev/nixos/swap
  mkfs.ext4 -L nix /dev/nixos/nix
  mkfs.ext4 -L root /dev/nixos/root
  mkfs.ext4 -L home /dev/nixos/home
  mkfs.ext4 -L docker /dev/nixos/docker
  

• mount filesystems:

  mount /dev/disk/by-label/root /mnt/
  mkdir -p /mnt/nix
  mount /dev/disk/by-label/nix /mnt/nix
  mkdir -p /mnt/home
  mount /dev/disk/by-label/home /mnt/home
  mkdir -p /mnt/var/lib/docker
  mount /dev/disk/by-label/docker /mnt/var/lib/docker
  mkdir -p /mnt/boot
  mount /dev/disk/by-label/boot /mnt/boot/
  swapon /dev/disk/by-label/swap
  

• generate nixos config: nixos-generate-config --root /mnt

• change hostname: sed -i 's/# networking\.hostName.*/networking.hostName = "apache";/' /mnt/etc/nixos/configuration.nix

• enable sshd with root login in /mnt/etc/nixos/configuration.nix:

  services.openssh = {
    enable = true;
    settings.PermitRootLogin = "yes";
  };
  

• configure luks initrd device:

  boot.initrd.luks.devices = {
    nixos = {
      device = "/dev/disk/by-uuid/`blkid /dev/sda2`";
      preLVM = true;
    };
  };
  

• run install and reboot:

  nixos-install
  reboot
  

• from other nixos, copy config to xps: scp -r nixos-config root@apache:

• ssh to xps: ssh root@apache

• rebuild with new config: nixos-rebuild switch
