ubuntu - Apache2 virtual host missing Document Root -

thank in advance.

i following tutorial digitalocean : https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-14-04-lts . completed instruction when start test configuration , add record parking domain, let example.com , digitalocean vps address 192.168.10.2. in schenario add these 3 virtual host 3 different documentroot:

1. /var/www/domainone.example.com/index.html
2. /var/www/domaintwo.example.com/index.html
3. /var/www/domainthree.example.com/index.html

then in parking domain add 3 different record below :

1. name : domainone.example.com address : 192.168.10.2
2. name : domaintwo.example.com address : 192.168.10.2
3. name : domainthree.example.com address : 192.168.10.2

when execute, happens follow :

1. url domainone.example.com goes /var/www/domainone.example.com/index.html
2. url domaintwo.example.com goes /var/www/domaintwo.example.com/index.html
3. but url domainthree.example.com goes /var/www/domaintwo.example.com/index.html

i sure wrote correct documentroot @ /etc/apache2/sites-available/(for each domain).config , restart apache2 service

thank again
