From your output:
no listening sockets available, shutting down
what basically means, that any port in which one apache is going to be listening is already being used by another application.
netstat -punta | grep LISTEN
Will give you a list of all the ports being used and the information needed to recognize which process is so you can kill
stop
or do whatever you want to do with it.
After doing a nmap
of your ip I can see that
80/tcp open http
so I guess you sorted it out.
