How to Set Up Apache Virtual Hosts

Virtual hosts let you serve multiple websites from a single Apache server.

Create a Virtual Host

Create /etc/apache2/sites-available/example.com.conf:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/html
    ErrorLog ${APACHE_LOG_DIR}/example.com-error.log
    CustomLog ${APACHE_LOG_DIR}/example.com-access.log combined
</VirtualHost>

Create Web Root

mkdir -p /var/www/example.com/html
echo "<h1>Hello from example.com</h1>" > /var/www/example.com/html/index.html
chown -R www-data:www-data /var/www/example.com

Enable the Site

a2ensite example.com.conf
systemctl reload apache2
