Web server

In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients". Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

The computer that a server program runs in is also frequently referred to as a server (Server machine).

How do I change the root directory of an apache server

https://www.digitalocean.com/community/tutorials/how-to-move-an-apache-web-root-to-a-new-location-on-ubuntu-16-04

Please note, that this only applies for Ubuntu 14.04 LTS and newer releases.

In my Ubuntu 14.04 LTS, the document root was set to /var/www/html. It was configured in the following file:

/etc/apache2/sites-available/000-default.conf

So just do a

sudo nano /etc/apache2/sites-available/000-default.conf

and change the following line to what you want:

DocumentRoot /var/www/html

Also do a

sudo nano /etc/apache2/apache2.conf

and find this

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

and change /var/www/html to your preferred directory

and save it.

After you saved your changes, just restart the apache2 webserver and you'll be done :)

sudo service apache2 restart
