How to Install IconCaptcha on Manjaro

IconCaptcha is a simple and effective captcha system developed by Fabian Wennink. In this tutorial, we will go through the steps to install IconCaptcha on Manjaro, a popular Linux distribution.

Prerequisites

Before we can start with the installation, we need to ensure that the following prerequisites are met:

• A Manjaro Linux installation with root access or sudo privileges.
• A web server with PHP installed, such as Apache or Nginx.
• Git, a version control system must be installed.

Step 1: Clone the IconCaptcha Repository

The first step is to get the IconCaptcha code from Github by cloning the repository. To accomplish this, follow the steps below:

1. Open the terminal on your Manjaro system.

2. Type the following command to install Git:

   sudo pacman -S git
   

3. Next, navigate to the web directory for your server. For Apache server, it is usually /var/www/html/ , and for Nginx, it's /usr/share/nginx/html/.

4. Clone the IconCaptcha Github repository using the following command:

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

5. This will download IconCaptcha code to your web directory.

Step 2: Configure the Captcha

Now, we need to create a configuration file for IconCaptcha. To do that:

1. Go to the IconCaptcha directory that you cloned in the previous step.

   cd IconCaptcha
   

2. Rename the config.example.php file to config.php.

   mv config.example.php config.php
   

3. Open the config.php file using a text editor, such as nano.

   sudo nano config.php
   

4. Customize the configuration settings such as the captcha type, the number of characters, and the fonts. Update the following line to select the captcha:

   define('ICON_CAPTCHA_LIBRARY', 'char;'); // Available libraries: char, sprite, greek, arabic, blackwhite.
   

   You can find more instructions on different options in the config.php file's comments.

5. Save and exit the configuration file.

Step 3: Test the Captcha

Now that we've installed and configured IconCaptcha, we need to verify it's working correctly. Follow these steps to test the captcha on your web server.

1. Navigate to your web server, and add /IconCaptcha/ to the URL.

2. You should be taken to the IconCaptcha demo page, which will display a captcha challenge.

3. Solve the captcha and click on Verify.

4. You should see a success message if the captcha was successful.

Congratulations! You have successfully installed IconCaptcha on Manjaro Linux. You can now integrate the captcha system into your own web applications.
