\mymulticolumn{1}{x{5.377cm}}{Apache2 ships with a virtual-host-friendly default configuration. That is, it is configured with a single default virtual host (using the VirtualHost directive) which can be modified or used as-is if you have a single site, or used as a template for additional virtual hosts if you have multiple sites. If left alone, the default virtual host will serve as your default site, or the site users will see if the URL they enter does not match the ServerName directive of any of your custom sites. To modify the default virtual host, edit the file \seqsplit{/etc/apache2/sites-available/000-default}.conf. \newline % Row Count 12 (+ 12)
If you wish to configure a new virtual host or site, copy that file into the same directory with a name you choose. For example: \newline % Row Count 15 (+ 3)

Konfiguracje stosujemy za pomocą dyrektyw (directives) : \newline % Row Count 6 (+ 2)
* ServerAdmin - dyrektywa określająca adres email administratora. Jeśli będzie problem z tą stroną, Apache2 wyświetli błąd wraz z tym emailem, jako adres pod który można zgłosić problem   \newline % Row Count 11 (+ 5)
* Listen - dyrektywa określa port lub adres IP i port, na którym Apache2 będzie nasłuchiwało. Jeśli adres IP nie jest wyszczególniony Apache2 będzie nasłuchiwało na wszystkich adresach IP. Domyślna wartość portu to 80.  \newline % Row Count 16 (+ 5)
* ServerName - opcjonalna dyrektywa określająca 'what FQDN your site should listen to'. The default virtual host has no ServerName directive specified, so it will respond to all requests that do not match a ServerName directive in another virtual host. \newline % Row Count 22 (+ 6)
* DocumentRoot - dyrektywa określa gdzie znajdują się pliki tworzące stronę. Domyślną wartością jest /var/www/html. \newline % Row Count 25 (+ 3)
Gdy skończymy z plikiem, to włączamy naszego nowego VirtualHosta używając do tego komendy a2ensite, i restartujemy Apache2: \newline % Row Count 28 (+ 3)
