Re: Unable to run Apache when listening on port 80
I am not familiar with BitNami, but from what I have read in the last few minutes it seems it might typically be installed by normal users and not administrators or root or superusers or whatever you want to call it. Thus you wouldn't have access to lower numbered port (below 1024, I think). Perhaps that is why it defaults to port 8080.
My suggestion is that you search around on the BiNami forum for further insight. (I am not saying we won't continue to try to help on this thread.)
Any follow-up information on your issue would be appreciated. Please have the courtesy to report back.
