The GitHub repository that you linked to has not been updated in over five years, so there is a good chance that the software will not work for you. However, it looks like a standard Drupal installation with some custom plugins, so you might be able to install it with a normal LAMP stack.

Here's how:

Install the Apache Web Server

  1. Open Terminal (if it's not already open)
  2. Update your sources:
    sudo apt update
  3. Install Apache:
    sudo apt install apache2
  4. If you are running UFW, allow Apache through:
    sudo ufw app list
    You will see something like this:
    Available applications:
       Apache Full
       Apache Secure
  5. Allow Apache to have access:
    sudo ufw allow in "Apache"
  6. Test Apache is working by visiting or http://localhost in your browser. You should see a standard Apache page.

Install the MySQL Database Server

  1. Install MySQL:
    sudo apt install mysql-server
  2. Configure the database server:
    sudo mysql_secure_installation
    You will be asked for a password, and if you want to remove example accounts and databases. Feel free to answer these questions any way you'd like.
  3. Test MySQL by connecting and creating a database and account for Book Crossing:
    sudo mysql
    If everything is good, you should now be connected to MySQL:
    mysql> CREATE DATABASE `drupal` DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
    mysql> CREATE USER 'books'@'localhost' IDENTIFIED WITH mysql_native_password BY 'superSecretPassword!123';
    mysql> GRANT ALL ON `drupal`.* TO 'books'@'localhost';
    Note: Do not copy the mysql> part. That's just to let you know it's a command for MySQL.
  4. Exit from MySQL:
    mysql> exit;

Install PHP

  1. Install PHP and some common packages:
    sudo apt install php libapache2-mod-php php-mysql php-xml php-json php-mbstring php-gd php-devel
  2. Restart Apache:
    sudo service apache2 restart
  3. Test PHP is working by creating a simple file in the /var/www/html directory:
    sudo vi /var/www/html/test.php
    Note: Feel free to use any text editor you prefer.
    Paste the following code into the new file:
    <?php phpinfo(); ?>
    Save the file.
  4. Check that PHP works by visiting or http://localhost/test.php in your browser. You should see a long page describing PHP with all the settings and packages.

Install Book Crossing

  1. Make sure you're in /var/www/html:
    cd /var/www/html
  2. Download the .zip file from GitHub to your /var/www/html directory:
    sudo wget https://github.com/bookcrossing/bkxng-core/archive/refs/heads/master.zip
  3. Unzip the file:
    sudo unzip master.zip
  4. Change permissions for all files and folders in the html directory to ensure Apache can access them all:
    sudo chown -R www-data:www-data /var/www/html
  5. Start the installation process by visiting or http://localhost/install.php in your browser.
  6. Follow the steps on the screen, remembering to enter the same MySQL account credentials as you created when testing MySQL earlier.

There are a lot of steps, but this is not too difficult so long as you go slow and pay attention the first few times you do this.
