[otrs] installing on virtual server

Hello, I run a hosting company, and I'd like to install OTRS to support my clients. But I don't want to install OTRS "globally" on the system. I just want to install it on the main account of my site ( /home/myaccount/ ). Is it possible? Is there a tutorial for that? The ones I read just teached how to install it as root Thanks, Luís Fernando
