(13)Permission denied: make_sock:

while starting apache i'm getting this error

(13)Permission denied: make_sock: could not bind to address [::]:80
no listening sockets available, shutting down
Unable to open logs

Plz guide me to resolve this issue..

Simple:
There is a rule that says any port under 1000 can only be used by root...

oracle_rajesh_k,

Please see if your system is already usng port 80.What user did you use for the apache service?
