Preliminary steps

Get a machine to deploy nix-bitcoin on. This could be a VirtualBox, a machine that is already running NixOS or a cloud provider. Have a look at the options in the NixOps manual.

Tutorial: install and configure NixOS for nix-bitcoin on VirtualBox

1. VirtualBox installation

The following steps are meant to be run on the machine you deploy from, not the machine you deploy to.

Add virtualbox.list to /etc/apt/sources.list.d (Debian 9 stretch)

echo "deb http://download.virtualbox.org/virtualbox/debian stretch contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

Add Oracle VirtualBox public key

wget https://www.virtualbox.org/download/oracle_vbox_2016.asc
gpg2 oracle_vbox_2016.asc

Proceed only if fingerprint reads B9F8 D658 297A F3EF C18D 5CDF A2F6 83C5 2980 AECF

sudo apt-key add oracle_vbox_2016.asc

Install virtualbox-5.2

sudo apt-get update
sudo apt-get install virtualbox-5.2

Create Host Adapter in VirtualBox
```
Open VirtualBox
File -> Host Network Manager -> Create
```
This should create a host adapter named vboxnet0

2. Nix installation

The following steps are meant to be run on the machine you deploy from, not the machine you deploy to.

Install Dependencies (Debian 9 stretch)

sudo apt-get install curl git gnupg2 dirmngr

Install latest Nix in "multi-user mode" with GPG Verification

curl -o install-nix-2.2.1 https://nixos.org/nix/install
curl -o install-nix-2.2.1.sig https://nixos.org/nix/install.sig
gpg2 --recv-keys B541D55301270E0BCF15CA5D8170B4726D7198DE
gpg2 --verify ./install-nix-2.2.1.sig
sh ./install-nix-2.2.1 --daemon

Then follow the instructions. Open a new terminal window when you're done.

If you get an error similar to

error: cloning builder process: Operation not permitted
error: unable to start build process
/tmp/nix-binary-tarball-unpack.hqawN4uSPr/unpack/nix-2.2.1-x86_64-linux/install: unable to install Nix into your default profile

you're likely not installing as multi-user because you forgot to pass the --daemon flag to the install script.

3. Nixops deployment

Clone this project

cd
git clone https://github.com/jonasnick/nix-bitcoin
cd ~/nix-bitcoin

Setup environment
```
nix-shell
```

Create nixops deployment in nix-shell.

nixops create network/network.nix network/network-vbox.nix -d bitcoin-node

Adjust configuration by opening configuration.nix and removing FIXMEs. Enable/disable the modules you want in configuration.nix.
Deploy Nixops in nix-shell
```
nixops deploy -d bitcoin-node
```
This will now create a nix-bitcoin node on the target machine.
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
```

See usage.md for usage instructions, such as how to update.

Tutorial: install and configure NixOS for nix-bitcoin on your own hardware

1. NixOS installation

This is borrowed from the NixOS manual. Look there for more information.

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

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
Boot the system

You will have to find out if your hardware uses UEFI or Legacy Boot for the next step.

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

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

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";
  };
}

Do the installation

nixos-install

Set root password

setting root password...
Enter new UNIX password: 
Retype new UNIX password:

If everything went well
```
reboot
```
