NixOS installation + +This is borrowed from the [NixOS manual](https://nixos.org/nixos/manual/index.html#ch-installation). Look there for more information. + +1. Obtain latest NixOS. For example: + + ``` + wget https://releases.nixos.org/nixos/18.09/nixos-18.09.2257.235487585ed/nixos-graphical-18.09.2257.235487585ed-x86_64-linux.iso + ``` + +2. Write NixOS iso to install media (USB/CD). For example: + + ``` + dd if=nixos-graphical-18.09.2257.235487585ed-x86_64-linux.iso of=/dev/sdX + ``` + Replace /dev/sdX with the correct device name. You can find this using `sudo fdisk -l` + +3. Boot the system + + You will have to find out if your hardware uses UEFI or Legacy Boot for the next step. + +4. Option 1: Partition and format for UEFI + + ``` + parted /dev/sda -- mklabel gpt + parted /dev/sda -- mkpart primary 512MiB -8GiB + parted /dev/sda -- mkpart primary linux-swap -8GiB 100% + parted /dev/sda -- mkpart ESP fat32 1MiB 512MiB + parted /dev/sda -- set 3 boot on + mkfs.ext4 -L nixos /dev/sda1 + mkswap -L swap /dev/sda2 + mkfs.fat -F 32 -n boot /dev/sda3 + mount /dev/disk/by-label/nixos /mnt + mkdir -p /mnt/boot + mount /dev/disk/by-label/boot /mnt/boot + swapon /dev/sda2 + ``` + +4. Option 2: Partition and format for Legacy Boot (MBR) + + ``` + parted /dev/sda -- mklabel msdos + parted /dev/sda -- mkpart primary 1MiB -8GiB + parted /dev/sda -- mkpart primary linux-swap -8GiB 100% + mkfs.ext4 -L nixos /dev/sda1 + mkswap -L swap /dev/sda2 + mount /dev/disk/by-label/nixos /mnt + swapon /dev/sda2 + ``` + +5. Generate NixOS config + + ``` + nixos-generate-config --root /mnt + nano /mnt/etc/nixos/configuration.nix + ``` + + Option 1: Edit NixOS configuration for UEFI + + ``` + { config, pkgs, ... }: { + imports = [ + # Include the results of the hardware scan. + ./hardware-configuration.nix + ]; + + boot.loader.systemd-boot.enable = true; + + # Note: setting fileSystems is generally not + # necessary, since nixos-generate-config figures them out + # automatically in hardware-configuration.nix. + #fileSystems."/".device = "/dev/disk/by-label/nixos"; + + # Enable the OpenSSH server. + services.openssh = { + enable = true; + permitRootLogin = "yes"; + }; + } + ``` + + Option 2: Edit NixOS configuration for Legacy Boot (MBR) + + ``` + { config, pkgs, ... }: { + imports = [ + # Include the results of the hardware scan. + ./hardware-configuration.nix + ]; + + boot.loader.grub.device = "/dev/sda"; + + # Note: setting fileSystems is generally not + # necessary, since nixos-generate-config figures them out + # automatically in hardware-configuration.nix. + #fileSystems."/".device = "/dev/disk/by-label/nixos"; + + # Enable the OpenSSH server. + services.openssh = { + enable = true; + permitRootLogin = "yes"; + }; + } + ``` + +6. Do the installation + + ``` + nixos-install + ``` + Set root password + ``` + setting root password... + Enter new UNIX password: + Retype new UNIX password: + ``` + +7. If everything went well + + ``` + reboot + ``` + +## 2. nix-bitcoin installation + +On the machine you are deploying from: + +1. Install Dependencies (Debian 9 stretch) + + ``` + sudo apt-get install curl git gnupg2 dirmngr + ``` + +2. Install Latest Nix with GPG Verification + + ``` + curl -o install-nix-2.1.3 https://nixos.org/nix/install + curl -o install-nix-2.1.3.sig https://nixos.org/nix/install.sig + gpg2 --recv-keys B541D55301270E0BCF15CA5D8170B4726D7198DE + gpg2 --verify ./install-nix-2.1.3.sig + sh ./install-nix-2.1.3 + . /home/user/.nix-profile/etc/profile.d/nix.sh + ``` + +3. Clone this project + + ``` + cd + git clone https://github.com/jonasnick/nix-bitcoin + cd ~/nix-bitcoin + ``` + +4. Create network file + + ``` + nano network-nixos.nix + ``` + + ``` + { + bitcoin-node = + { config, pkgs, ... }: + { deployment.targetHost = 1.2.3.4; + }; + } + ``` + + Replace 1.2.3.4 with NixOS machine's IP address. + +5. Edit `configuration.nix` + + ``` + nano configuration.nix + ``` + + Uncomment `./hardware-configuration.nix` line by removing #. + +6. Create `hardware-configuration.nix` + + ``` + nano hardware-configuration.nix + ``` + Copy contents of NixOS machine's `hardware-configuration.nix` to file. + +7. Add boot option to `hardware-configuration.nix` + + Option 1: Enable systemd boot for UEFI + ``` + boot.loader.grub.device = "/dev/sda"; + ``` + Option 2: Set grub device for Legacy Boot (MBR) + ``` + boot.loader.grub.device = "/dev/sda": + ``` + +8. Setup environment + ``` + nix-shell + ``` + +9. Create nixops deployment in nix-shell. + ``` + nixops create network.nix network-nixos.nix -d bitcoin-node + ``` + +10. Adjust configuration by opening configuration.nix and removing FIXMEs. + +11. Deploy Nixops in nix-shell + + ``` + nixops deploy -d bitcoin-node + ``` + This will now create a nix-bitcoin node on the target machine. + +12. Nixops automatically creates an ssh key for use with `nixops ssh`. Access `bitcoin-node` through ssh in nix-shell with + + ``` + nixops ssh operator@bitcoin-node + ``` +
