***   Change the Root Directory of an Apache server
( https://www.geeksforgeeks.org/linux-unix/how-to-change-the-root-directory-of-an-apache-server/ )

config file:
Ubuntu/Debian: /etc/apache2/sites-available/000-default.conf

    Find the DocumentRoot directive. It will look something like this:

DocumentRoot /var/www/html

    Change the path to your desired directory. For example, if you want to change it to /home/yourusername/public_html_gfg, modify the line to:

DocumentRoot /home/yourusername/gfg_html

    Update the <Directory> section if present. You might find a section that looks like this:

<Directory /var/www/html>
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

    Change it to match your new DocumentRoot:

<Directory /home/yourusername/gfg_html>
Options Indexes FollowSymLinks
  AllowOverride None
  Require all granted
</Directory>

Step 3: Update Permissions

    Make sure the Apache user (normally www-data or apache) has the read permission on the new directory. You can adjust the permissions using:You can adjust the permissions using:

sudo chown -R www-data:www-data /home/yourusername/gfg_html
sudo chmod -R 755 /home/yourusername/gfg_html

Step 4: Test the Configuration

    It is a good idea to check the settings for syntax issues before restarting Apache:

sudo apachectl configtest

Step 5: Restart Apache

    Restart Apache to apply the changes:

$ sudo service apache2 restart

Step 6: Verify the Change

To test the effectiveness of changing the root directory, open your web browser and enter your server’s IP address/domain name. You should see the content from the new DocumentRoot directory you created.
