How to install into linux hosting?

Hello all,
I am new year. I have website
http://www.occau.com/musicalinstruments. I want to track all the information like refferal and other just to this page not other page.

Though actually i am taking other external site to track it.
But i want to use this software to track.

I am running under linux hosting and php and mysql (database).
Could you please tell me how to setup this software.

On the other hand i would like to track the refferal that come searching with the keyword musical instruments.

I would be grateful if somebody tell me about this.

Thank you
waiting for your reply.

I hope you understand what i wanted.
