Hi Ayman,
Welcome to OpenACS. Anyway for me normally when I have a new installed OpenACS I normally run it on a command line and tail -f myserver.log. Normally I forget some stuff and a couple of errors along the way.
Using inittab or daemon tools will make your process restart if it dies even if its because of an error so its not a good idea to use them for your initial startup. Try the normal command line and tail and log file and see if there are any errors. Good luck.
