How to Install AsmBB on NixOS Latest?

AsmBB is a lightweight forum software written in assembly language, suitable for small to medium-sized communities. In this tutorial, we will guide you through the process of installing AsmBB on NixOS Latest.

Prerequisites

Before we start, make sure you have the following:

A server running NixOS Latest
A terminal with sudo privileges

Step 1: Enable Nixpkgs Unstable

AsmBB is not yet available in the stable channel of Nixpkgs. Therefore, we need to enable the unstable channel to access the package.

Open the /etc/nixos/configuration.nix file with your favorite text editor.

Add the following line to the imports section:

imports = [ <nixpkgs-unstable/lib/modules.nix> ];

Save and close the file.
Run the following command to activate the new configuration:
```
sudo nixos-rebuild switch
```

Step 2: Install AsmBB

Now that we have enabled the unstable channel, we can install AsmBB using the following command:

sudo nix-env -i asm32-asm1x-asm1x

This will install the AsmBB package and all its dependencies.

Step 3: Configure AsmBB

Before we can use AsmBB, we need to create a configuration file. Here's an example configuration file:

#!/usr/bin/env bash

BOARD_TITLE="My AsmBB Board"
BOARD_GUEST="1"
BOARD_GUEST_NAME="Guest"
GZIP="on"
USE_CAPTCHA="on"

SQL_DBNAME="asm_bb_db"
SQL_USER="asm_bb_user"
SQL_PASS="my_password"
SQL_HOSTNAME="localhost"

Save the above code as my_config.sh in a directory of your choice. Be sure to replace the values of SQL_* with your own.

To manually run AsmBB, use the following command:

/admin.pl -m -v -c my_config.sh

To have AsmBB run automatically when the server starts up, create a systemd service unit file:

Create a directory for the service unit file:

sudo mkdir /etc/systemd/system/asm-bb.service.d

Create a new file called override.conf in the new directory:

sudo nano /etc/systemd/system/asm-bb.service.d/override.conf

Add the following lines to the file:
```
[Service]
ExecStart=
ExecStart=/usr/bin/env /usr/bin/perl /path/to/asm_bb_dir/admin.pl -m -v -c /path/to/config.sh
```
Replace /path/to/asm_bb_dir and /path/to/config.sh with the actual paths to your AsmBB installation directory and configuration file, respectively.
Save and close the file.
Reload the systemd daemon:
```
sudo systemctl daemon-reload
```
Start the service:
```
sudo systemctl start asm-bb
```

AsmBB is now up and running on your NixOS server.
