Apache will not restart - How to force restart?

[kpmedia]

Ran into an issue today, Apache webserver would not restart (Plesk 9, CentOS Linux, Apache 2)

Kept getting this while logged in to root:

Address already in use: make_sock: could not bind to port 80

The solution was to:

killall -9 httpd

and then restart Apache with:

service httpd start

And it was back -- and even faster than before it went down.

Easy!
