I just look around for a helpdesk system and found OTRS have alot of features. But unlucky, i can not install it on my site yet.

Could anyone help me to install OTRS using cPanel ? If it possible please teach me step by step.

Do you have root on the server or just a hosting account? cPanel doesn't really have anything to do with installing OTRS though. You'll need an SSH connection to your server and install a package or install from a source .tar.gz. Just check out the documentation: http://doc.otrs.org/2.0/en/html/c218.html Nils Breunese.
