Install Drupal on Debian 10 - Step by Step Process ?

This article covers how to setup Drupal on Debian Linux System.

Drupal is a powerful CMS that allows you to design stunning websites and blogs with simple tools and drag and drop features in a matter of a few hours.
It offers flexibility in terms of customization of your site to meet your desired results.
You can easily get started with free templates before advancing to premium templates that have more features.

To Configure Apache 2.4:
1. Enable Apache's rewrite module. This module is necessary since Drupal 8 enables Clean URLs by default;

$ sudo a2enmod rewrite

2. Specify the rewrite conditions for your Drupal site’s document root in Apache's configuration file using the text editor of your choice.
If you installed and configured your Apache server using LAMP stack on Debian 10 guide, the configuration file for your site is located at /etc/apache2/sites-available/example.com.conf.
File: /etc/apache2/sites-available/example.com.conf:

<Directory /var/www/html/example.com/public_html>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
          RewriteEngine on
          RewriteBase /
          RewriteCond %{REQUEST_FILENAME} !-f
          RewriteCond %{REQUEST_FILENAME} !-d
          RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

3. Change the ownership of your site's document root from root to www-data. This allows you to install modules and themes, and to update Drupal, without being prompted for FTP credentials.

$ sudo chown -R www-data:www-data /var/www/html/example.com

4. Restart Apache so all changes are applied.

$ sudo systemctl restart apache2
