Installing IconCaptcha on nixOS Latest

IconCaptcha is a captcha plugin that replaces the traditional text-based captcha system with a set of icons that are easier for humans to identify. In this tutorial, we will be discussing how to install IconCaptcha on nixOS latest using Nix package manager.

Step 1: Install Nix

To install Nix on your system, you can run the following command:

$ curl https://nixos.org/nix/install | sh

This will download and install Nix on your system.

Step 2: Clone the IconCaptcha repository

Next, you need to clone the IconCaptcha repository from Github. To do this, run the following command:

$ git clone https://github.com/fabianwennink/IconCaptcha.git

This will download the repository to your local machine.

Step 3: Install dependencies

IconCaptcha requires PHP and MySQL to be installed on the system. On nixOS, you can install these dependencies using nix package manager.

$ nix-env -i php
$ nix-env -i mysql

Step 4: Configure MySQL

To setup MySQL, you need to create a new database and user. To do this, you can use the following commands:

$ mysql -u root -p

This will open the MySQL command-line interface. Once there, you can create a new database and user.

mysql> CREATE DATABASE iconcaptcha;
mysql> CREATE USER 'iconcaptcha'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON iconcaptcha.* TO 'iconcaptcha'@'localhost';
mysql> FLUSH PRIVILEGES;
mysql> EXIT;

Replace the password with a secure password of your choice.

Step 5: Configure PHP

Next, you need to configure PHP to work with IconCaptcha. To do this, you need to edit the php.ini file. You can open this file using the following command:

$ sudo nano /etc/php.ini

In the file, locate the following line and uncomment it:

extension=pdo_mysql.so

Save the file and exit.

Step 6: Install Composer

IconCaptcha uses Composer to manage its PHP dependencies. To install Composer on your system, run the following command:

$ sudo nix-env -iA nixpkgs.composer

Step 7: Install IconCaptcha dependencies

To install IconCaptcha dependencies, navigate to the IconCaptcha directory and run the following command:

$ composer install

This will download and install all the required dependencies.

Step 8: Configure IconCaptcha

To configure IconCaptcha, you need to create a new configuration file. Navigate to the IconCaptcha directory and copy the "config.sample.php" file to "config.php".

$ cd IconCaptcha/
$ cp config.sample.php config.php

Open the newly created "config.php" file using your preferred text editor and set the database details.

$config = [
    'db_host' => 'localhost',
    'db_user' => 'iconcaptcha',
    'db_password' => 'password',
    'db_name' => 'iconcaptcha'
];

Save the file and exit.

Step 9: Start the web server

To start the web server, navigate to the IconCaptcha directory and execute the following command:

$ php -S localhost:8000

This will start the web server and make the application available at "http://localhost:8000/"

Congratulations! You have successfully installed and configured IconCaptcha on nixOS latest. Now you can start using this captcha plugin on your website.
