Hi,

I just bought an SSL cert and installed on my Apache server. When I restarted something went wrong so I had to change some config stuff and when I tried to restart apache for the second time I got this:

$ sudo apache2ctl start
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

Problem is that apache isn't running. For some reason there is something hogging my tcp 80 port, preventing apache from starting properly. How do I fix this? Is there a way to "free" a port?

find what process is using the resource, using "netstat -plnt" and then kill -9 that pid.

not a Networking question, moved to Linux - General.
