# Installation
|
|
|
|
This is a full NixOS installation guide, from live cd to a working OS.
|
|
Once done, you will be left with a complete system, that uses my configuration.
|
|
|
|
This installation will push to use flakes out of the box, configuration.nix will
|
|
only be needed to add support for flakes and rebuild.
|
|
|
|
## Live ISO
|
|
|
|
This assumes you've chosen one of the ISO images with a graphical installer, and
|
|
followed though with the installation, getting you to a basic NixOS installation.
|
|
|
|
During this installation, make sure you allow non-free programs, and in the desktop environment selection, pick the option without any DE, we'll get to install that ourselves.
|
|
|
|
## Set up configuration.nix
|
|
|
|
First thing you'll need to do is to make your useer account own the
|
|
`/etc/nixos` directory. You'll want to do this to allow you to easily manage
|
|
your config with git (which is a requirement when using flakes). You can use
|
|
system wide git, however it is much more convenient to just leave it to the
|
|
user, as you'll have your git configuration there.
|
|
|
|
```sh
|
|
cd /etc/nixos
|
|
sudo chmod -R itsdrike:users .
|
|
```
|
|
|
|
Out of the box, NixOS only comes with `nano` editor, so we'll have to use that to edit the `configuration.nix` for the first time.
|
|
|
|
```sh
|
|
nano configuration.nix
|
|
```
|
|
|
|
In there, change the `environment.systemPackages = with pkgs; [];` like, and include `git` and `vim`.
|
|
|
|
After that, let's enable flakes, by adding the following at the end of your `configuration.nix` (but still within the function body - before the last `}`):
|
|
|
|
```nix
|
|
nix = {
|
|
package = pkgs.nixUnstable;
|
|
extraOptions = ''
|
|
experimental-features = nix-command flakes
|
|
''
|
|
};
|
|
```
|
|
|
|
Now you can save the changes and rebuild the system:
|
|
|
|
```sh
|
|
sudo nixos-rebuild switch
|
|
```
|
|
|
|
## Set up flakes
|
|
|
|
Now, since a git repository is required for flakes, let's set up git:
|
|
|
|
```sh
|
|
git config --global user.email "itsdrike@protonmail.com"
|
|
git config --global user.name "ItsDrike"
|
|
```
|
|
|
|
Now we have 2 options, the first one I'll show will set up my configuration
|
|
from this repository. Once done, you will have your system set up in the same
|
|
way that I do. In the second option, I will go over a basic setup to create
|
|
your own flake.
|
|
|
|
## Set up with my configuration
|
|
|
|
Finally, we're ready to migrate to flakes. At this point, you can simply pull this repository
|
|
to the `/etc/nixos` directory, to get my setup, like so:
|
|
|
|
```sh
|
|
git init
|
|
git remote add origin https://github.com/ItsDrike/nixdots
|
|
git branch -M main
|
|
git pull origin main
|
|
```
|
|
|
|
## Create your own custom flake
|
|
|
|
Initialize an empty git repository:
|
|
|
|
```sh
|
|
git init
|
|
```
|
|
|
|
Create a very basic `/etc/nixos/flake.nix`:
|
|
|
|
```sh
|
|
{
|
|
description = "ItsDrike's NixOS configuration";
|
|
|
|
inputs = {
|
|
# the version here should match your system.stateVersion in configuration.nix
|
|
nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.11";
|
|
};
|
|
|
|
outputs = { self, nixpkgs, ...} @ inputs: {
|
|
nixosConfigurations = {
|
|
nixos = nixpkgs.lib.nixosSystem {
|
|
system = "x86_64-linux";
|
|
modules = [ ./configuration.nix ];
|
|
};
|
|
};
|
|
};
|
|
}
|
|
```
|
|
|
|
This flake will still rely on your `configuration.nix`, we will eventually get
|
|
to a config which does not need this file, but to make starting out with flakes
|
|
simple, we'll do it in this way for now.
|
|
|
|
Let's add things to git!
|
|
|
|
```sh
|
|
git add flake.nix
|
|
git add configuration.nix
|
|
git add hardware-configuration.nix
|
|
```
|
|
|
|
Now you can run `sudo nixos-rebuild switch`. Yay, you're now using NixOS in flakes mode!
|
|
|
|
> [!NOTE]
|
|
> If you run the `sudo nixos-rebuild switch` command before adding all of these
|
|
> files to git, you will get an error, so it really is a requirement to have
|
|
> your configuration in a git repository when you're using flakes.
|
|
|
|
You can notice that this also created a `flake.lock` file, containing the exact
|
|
versions of all of the packages you're using. Let's add this file to git too:
|
|
`git add flake.lock`.
|
|
|
|
And now we're ready to make our first commit:
|
|
|
|
```sh
|
|
git commit -m "Initial commit"
|
|
```
|
|
|
|
## Updating
|
|
|
|
Over time, to update the software that's installed on your machine, you can use
|
|
`nix flake update`, to update your `flake.lock` file, and then `nixos-rebuild
|
|
switch`, to get switch your system to the new dependencies.
|
|
|
|
> [!TIP]
|
|
> This replaces the legacy (non-flake) regime's command: `nixos-rebuild switch --upgrade`
