OpenTracker is a simplistic, lightweight, standards-compliant BitTorrent peer tracker. It is written in PHP and requires only a single MySQL table to function. It does not create or use files on disk, nor is it a continuously executing process, making it ideal for virtual web hosts.
Compared with other popular trackers, OpenTracker is limited.
It provides no interface for searching or viewing files or statistics. Rather, it is purely a tracker, plain and simple, which in many cases is just what is wanted.

Install:
To run OpenTracker, you need two things: a web server that supports PHP,
and a MySQL database. PHP should be set for magic_quotes_gpc off.
Execute the included dbschema.sql on your database.
This will create the table required by OpenTracker, which is named "peers" by default.
You may rename the table if desired.
Edit config.inc.php,
filling in the appropriate information for your database setup.
That's all there is to it.
Create a torrent using announce.php on your server as the announce URL, and away you go.
