Installing Lila on NixOS

Lila is a free, open-source chess server which allows users to play, learn and analyze chess games. In this tutorial, we will go through the steps required to install Lila on the latest version of NixOS.

Step 1: Update your system

Before we can install Lila on our system, it's important to ensure that our system is up-to-date. To do so, open your terminal and run the following command:

sudo nix-channel --update && sudo nixos-rebuild switch

This command updates your NixOS channels, and applies any pending system updates.

Step 2: Install Lila

To install Lila, we will use a package nixpkgs which is available in the official NixOS repository. To install it, run the following command:

sudo nix-env -iA nixpkgs.lila

This command installs Lila on your system.

Step 3: Configure Lila

Once Lila is installed on your system, you need to configure it to your liking. The configuration file for Lila is located at /etc/lila/lila.conf. You can edit this file using your favorite text editor.

Here is an example configuration file:

session {
  secret = "secret_token"
}

http {
  interface = "0.0.0.0"
  port = 8080
}

database.default {
  url = "jdbc:postgresql://localhost/lila"
  username = "username"
  password = "password"
}

security {
  domain = "example.com"
}

Note: Don't forget to change the secret, username, password, and domain values with your own.

Step 4: Start Lila

To start Lila on your system, run the following command:

sudo systemctl start lila

This command starts Lila as a systemd unit.

Step 5: Enable Lila

If you want Lila to start automatically at system startup, run the following command:

sudo systemctl enable lila

This command enables the Lila systemd unit.
