Apache – Address already in use: make_sock: could not bind to address

08/06/2005 This error message can be caused by an improper shut down, the apache processes are still hanging around and apachectl restart won’t work.

Solution

just kill off the hanging processes:

# fuser 80/tcp
80/tcp:               3010  3702  4088 16754
# kill -n 9 3010
# kill -n 9 3702
# kill -n 9 4088
# kill -n 9 16754
# apachectl start

or if there’s loads of processes use
#for i in $(fuser 80/tcp);do kill -n 9 $i;done
to kill them all off
