How to Install Elgg on nixOS Latest

Elgg is an open-source social networking software that allows users to create and manage a social network. In this tutorial, we will guide you through the process of installing Elgg on nixOS.

Prerequisites

• A nixOS machine
• sudo privileges
• Basic knowledge of nixOS

Step 1: Update the System

It is always a good practice to update your system before installing any packages. You can update your nixOS system by running the following command:

sudo nixos-rebuild switch

Step 2: Install Nixpkgs

Elgg is not included in the default nixOS package repository, so we will need to install the nixpkgs-unstable channel.

sudo nix-channel --add https://nixos.org/channels/nixpkgs-unstable unstable
sudo nix-channel --update

Step 3: Install Elgg

Now that the unstable nixpkgs channel is installed, we can install Elgg using the following command:

sudo nix-env -iA nixpkgs-unstable.elgg

Step 4: Configure and Start Elgg

Before we can start using Elgg, we need to create a configuration file.

Create a new file called elgg.ini in the /etc/nixos directory and add the following configuration options:

[nginx]
enable = true
sslCert = "/etc/nixos/elgg.crt"
sslCertKey = "/etc/nixos/elgg.key"

[php]
memoryLimit = 256M

Next, we will need to create the SSL certificate and key files.

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nixos/elgg.key -out /etc/nixos/elgg.crt

Now, we can start Elgg by running the following command:

sudo systemctl start elgg
