starting daemons at server start

[Micke P]

Hi Subhro :-),

Good information. After checking, I didn't have the
"local_startup" line in my /etc/rc.conf file. 

This didn't work on restarting just now, but I added
the line pointing to the rc.d apache dir where I had
added the file apache.sh earlier (below). Still had to
start apache by hand. I don't know if the script is
correct, because there was no example script and I
changed the script from another daemon. If so, I'm
still missing something.

       ;;

       /usr/local/apache/bin/apachectl stop
       ;;

       echo "Usage: 'basename $0' (start|stop)" >&2
       exit 64
       ;;
esac

exit 0
