Drupal is a powerful open-source content management system (CMS) known for its flexibility and extensibility, making it an ideal choice for developers, marketers, and agencies to build complex websites and applications. This guide is designed to help newcomers navigate the process of installing Drupal on Ubuntu 23.04, offering detailed instructions with real command-line examples for each step of the installation and configuration process.

Step 1: Install Apache and PHP Extensions

Drupal requires a web server and PHP to run. Although you might already have Apache installed from the LAMP stack setup, you need to install specific PHP extensions that Drupal depends on.

1. Update your package index:

   sudo apt update

2. Install PHP extensions required by Drupal:

   sudo apt install php-gd php-xml php-mbstring php-json php-mysql -y

Step 2: Create a MySQL Database and User for Drupal

Drupal stores its content in a database. Here’s how to create a MySQL database and a user for Drupal:

1. Log in to MySQL as the root user:

   sudo mysql -u root -p

2. Create a database for Drupal:

   CREATE DATABASE drupal_db;

3. Create a MySQL user and grant all privileges on the Drupal database:

   CREATE USER 'drupal_user'@'localhost' IDENTIFIED BY 'password';
   GRANT ALL PRIVILEGES ON drupal_db.* TO 'drupal_user'@'localhost';
   FLUSH PRIVILEGES;
   EXIT;

Make sure to replace 'password' with a strong password of your choice.

Step 3: Install Drupal

With the environment ready, you can proceed to download and install Drupal.

1. Navigate to the Apache web root directory:

   cd /var/www/html

2. Download the latest version of Drupal: You can find the latest version of Drupal on the official Drupal website. Use wget to download it directly to your server, for example:

   sudo wget https://www.drupal.org/download-latest/tar.gz -O drupal.tar.gz

3. Extract the Drupal archive and move it to a directory named drupal:

   sudo tar -zxvf drupal.tar.gz
   sudo mv drupal-* drupal

4. Set the correct permissions for the Drupal directory:

   sudo chown -R www-data:www-data /var/www/html/drupal
   sudo chmod -R 755 /var/www/html/drupal

Step 4: Configure Apache for Drupal

Create an Apache virtual host file for your Drupal site.

1. Create a new Apache configuration file for Drupal:

   sudo nano /etc/apache2/sites-available/drupal.conf

2. Add the following configuration to the file, adjusting ServerAdmin, ServerName, and DocumentRoot as necessary:

   <VirtualHost *:80>
       ServerAdmin admin@example.com
       ServerName example.com
       DocumentRoot /var/www/html/drupal

       <Directory /var/www/html/drupal>
           AllowOverride All
           Order allow,deny
           allow from all
       </Directory>

       ErrorLog ${APACHE_LOG_DIR}/error.log
       CustomLog ${APACHE_LOG_DIR}/access.log combined
   </VirtualHost>

3. Enable the new site and Apache’s rewrite module, then restart Apache:

   sudo a2ensite drupal.conf
   sudo a2enmod rewrite
   sudo systemctl restart apache2

Step 5: Finalize Drupal Installation

Navigate to your website in a web browser and follow the Drupal installation process. You’ll need to enter the database details you created earlier and configure your site settings.
