How to point default virtual host in Ubuntu 14.04 LTS - php

Question

I recently purchased linode hosting where i did successfully hosted a website. And its opening by domain-name.com and also when i enter server IP it opens default /var/www/domain-name.com/public_html
Now i want to host another site in it and created another virtual host with domain-name-2.com and enabled that and did reload my apache server.
Now when i enter again the server IP in browser like http://11.22.33.44/ it shows the first website (/var/www/domain-name.com/public_html) i hosted by default.
But i want to point some other folder so that when i hit http://11.22.33.44 it will show that folder's index.html not /var/www/domain-name.com/public_html
How to do that?

Answer 1

Not sure if I understand correctly, you want
http://11.22.33.44/ -> /var/www/domain-name.com/some_other_folder
http://domain-name.com/ -> /var/www/domain-name.com/public_html
Am I correct?
If that is the case, go to /etc/apach2/site-available
in 000-default.conf
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/domain-name.com/some_other_folder
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Create a new file called "domain-name.com.conf" in the same folder
Write the following into the file:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/domain-name.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
To enable virtual host, type into terminal:
$ sudo a2ensite domain-name.com

Basically 000-default.conf wasn't working as it was disabled.
enable it by following command -
sudo a2ensite 000-default.conf
I was wondering why it opening my 000-domain-name.com.conf it's because may be as default conf has been disabled so apache search for other conf file alphabetically as act that as default conf.
Also if you want to disable default conf
sudo a2dissite 000-default.conf
Both above command require apache to be restarted by following command -
sudo service apache2 restart
