How to install

Hello has a bill in the dreamhost and I am trying to install the site
OTRS - Open Ticket Request System

but I don’t know anything much less of linux of perl, seeking in the internet, I got myself to connect in the site through telnet, and I tried to install the package otrs_1.3.2p01-6_all.deb
but of the mistake of permission of user root
I ordered a message in the support, but they said that for me to have the password root need a dedicated servant

Did anybody get to install??? could he/she make a how-to?
or then I could aid myself with the installation?
