How to Install IconCaptcha on Arch Linux

This tutorial will guide you through the installation process of IconCaptcha on Arch Linux.

Requirements

Before we begin, make sure you have the following requirements:

• A running instance of Arch Linux
• LAMP stack installed (Apache, MySQL, PHP)
• A web browser

Step 1: Download the IconCaptcha package

The first step is to download the IconCaptcha package from https://www.fabianwennink.nl/projects/IconCaptcha/.

You can either download it directly or use git to clone the repository:

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

Step 2: Extract the files

After downloading the package, extract the files into your web server's root directory. For example, if your web server root directory is located at /var/www/html, run the following command:

$ sudo unzip IconCaptcha.zip -d /var/www/html/

Step 3: Configure the database

Create a new MySQL database and user for IconCaptcha:

$ mysql -u root -p

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

Edit the db_config.inc.php file and modify the database settings to reflect the database and user you just created:

$ sudo nano /var/www/html/IconCaptcha/db_config.inc.php

define('DB_HOST', 'localhost');
define('DB_USER', 'iconcaptchauser');
define('DB_PASS', 'password');
define('DB_NAME', 'iconcaptcha');

Save and exit the file.

Step 4: Create the database tables

The next step is to create the necessary database tables. Log in to the MySQL console and execute the following commands:

$ mysql -u root -p iconcaptcha < /var/www/html/IconCaptcha/iconcaptcha.sql

Step 5: Configure the web server

To allow the web server to access the files, set the correct ownership and permissions:

$ sudo chown -R http:http /var/www/html/IconCaptcha
$ sudo chmod -R 755 /var/www/html/IconCaptcha

Create a virtual host configuration for IconCaptcha:

$ sudo nano /etc/httpd/conf/extra/httpd-iconcaptcha.conf

Add the following lines to the file:

<VirtualHost *:80>
    ServerName iconcaptcha.example.com
    DocumentRoot /var/www/html/IconCaptcha
    ErrorLog /var/log/httpd/iconcaptcha-error_log
    CustomLog /var/log/httpd/iconcaptcha-access_log common
</VirtualHost>

Save and exit the file.

Restart the web server for the changes to take effect:

$ sudo systemctl restart httpd

Step 6: Access IconCaptcha

Open your web browser and go to http://iconcaptcha.example.com. You should see the IconCaptcha interface.

Congratulations! You have successfully installed IconCaptcha on Arch Linux.
