## 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`
