Set different data/folders for different domains on apache - apache

Question

So I have Ubuntu 16 installed with LAMP and couple of other things on it (like FTP server...).
IP of my VPS is 1.2.3.4.
I have 2 domains, example.com and mydomain.com - both of these domains have their A record pointed at 1.2.3.4
If I access 1.2.3.4 and example.com and mydomain.com in my browser, all those three are showing the SAME data, specifically the contents of /var/www/html - if I change content of this directory it affects example.com and mydomain.com and the 1.2.3.4.
Now how can I set additional folders for domains to read from? I want different data on example.com and on mydomain.com - I want to make them read from different folder on server. How can i setup this please?

What you want to achieve is technically defined as setting virtual hosts which could be set using the following steps:
Under your Apache configurations directory, usually at /etc/apache2/, you will find a directory named sites-enabled.
For each of your domains, you will need to configure a special configuration file in order to point them to the right direction. The name of the file is typically your-domain.conf.
Here's an example of the file:
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port
# that the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
ServerName your_domain
ServerAlias www.your_domain
ServerAdmin webmaster#your_domain
DocumentRoot website_directory
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
<Directory website_directory>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
After saving the file you will need to restart the Apache server
/etc/init.d/apache2 restart
Repeat the above steps for each of your domains.
If everything goes right, your site will show when you access your domain.
