How to install IconCaptcha on Ubuntu Server Latest

In this tutorial, we will be installing IconCaptcha, a captcha alternative that uses icons instead of distorted text, on Ubuntu Server Latest.

Prerequisites

Before installing IconCaptcha, make sure you have the following:

• Ubuntu Server Latest installed on your system
• Apache web server installed and running
• PHP 7.0 or higher installed and running

Step 1: Download IconCaptcha

The first step is to download the IconCaptcha source code from its official website. You can do this by visiting the following link:

https://www.fabianwennink.nl/projects/IconCaptcha/download/

Choose the latest release and download the ZIP file.

Step 2: Extract the archive

Once the ZIP file is downloaded, extract the contents of the archive to the /var/www/html directory. You can do this by running the following command:

sudo unzip IconCaptcha-x.y.z.zip -d /var/www/html/

Note: Replace x.y.z with the version number you downloaded.

This will create a new directory called IconCaptcha-x.y.z in the /var/www/html directory.

Step 3: Set up permissions

Before we can use IconCaptcha, we need to set up some permissions. Run the following command to change the ownership of the IconCaptcha-x.y.z directory to the Apache user:

sudo chown -R www-data:www-data /var/www/html/IconCaptcha-x.y.z

Next, give the uploads directory write permission:

sudo chmod 777 /var/www/html/IconCaptcha-x.y.z/uploads

Step 4: Configure Apache

We need to configure Apache to serve the IconCaptcha files. Edit the Apache configuration file /etc/apache2/sites-available/000-default.conf:

sudo nano /etc/apache2/sites-available/000-default.conf

Add the following lines to the <VirtualHost> section:

DocumentRoot /var/www/html/IconCaptcha-x.y.z/
<Directory /var/www/html/IconCaptcha-x.y.z/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
</Directory>

Save and exit the file.

Restart Apache for the changes to take effect:

sudo systemctl restart apache2

Step 5: Test IconCaptcha

Open a web browser and go to http://<your_server_IP_address>/IconCaptcha-x.y.z/demo.php (replace <your_server_IP_address> with your server's IP address). If everything is set up correctly, you should see the IconCaptcha demo page.

Congratulations, you have successfully installed IconCaptcha on Ubuntu Server Latest!

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
