## How to install NixOS on Orange Pi 5 Plus
|
|
|
|
### 1. Prepare a USB LUKS key
|
|
|
|
Generate LUKS keyfile to encrypt the root partition, it's used by disko.
|
|
|
|
```bash
|
|
# partition the usb stick
|
|
DEV=/dev/sdX
|
|
parted ${DEV} -- mklabel gpt
|
|
parted ${DEV} -- mkpart OPI5P_DSC fat32 0% 512MB
|
|
mkfs.fat -F 32 -n OPI5P_DSC ${DEV}1
|
|
|
|
# Generate a keyfile from the true random number generator
|
|
KEYFILE=./orangepi5plus-luks-keyfile
|
|
dd bs=512 count=64 iflag=fullblock if=/dev/random of=$KEYFILE
|
|
|
|
# copy the keyfile and token to the usb stick
|
|
KEYFILE=./orangepi5plus-luks-keyfile
|
|
DEVICE=/dev/disk/by-label/OPI5P_DSC
|
|
# seek=128 skip N obs-sized output blocks to avoid overwriting the filesystem header
|
|
dd bs=512 count=64 iflag=fullblock seek=128 if=$KEYFILE of=$DEVICE
|
|
```
|
|
|
|
### 2. Partition the SSD & install NixOS via disko
|
|
|
|
First, follow
|
|
[UEFI - ryan4yin/nixos-rk3588](https://github.com/ryan4yin/nixos-rk3588/blob/main/UEFI.md) to
|
|
install UEFI bootloader and boot into NixOS live environment via a USB stick.
|
|
|
|
Then, run the following commands:
|
|
|
|
```bash
|
|
# transfer the nix-config to the target machine
|
|
rsync -avzP ~/nix-config rk@<ip-addr>:/home/rk/
|
|
|
|
# login via ssh
|
|
ssh rk@<ip-addr>
|
|
|
|
cd ~/nix-config/hosts/12kingdoms_rakushun
|
|
# 1. change the disk device path in ./disko-fs.nix to the disk you want to use
|
|
# 2. partition & format the disk via disko
|
|
sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko ./disko-fs.nix
|
|
|
|
|
|
cd ~/nix-config
|
|
# install nixos
|
|
# NOTE: the root password you set here will be discarded when reboot
|
|
sudo nixos-install --root /mnt --flake .#rakushun --no-root-password --show-trace --verbose
|
|
```
