My webbserver act as a torrentclient as well.
To start rtorrent in background I using the command screen to do this.
This is how I do:

Your have now started rtorrent in a screen named rtorrent, how to access is just type

And to exit, hold on Ctrl and A release and then press D. Now your are out of rtorrent screen and it still running i background.
