I have centOS 6.4 64bit and apache2 (httpd) installed. I do:

 /etc/init.d/httpd start     

And Apache starts up fine with just a green [Ok]

However; when I try to load any webpages hosted on it they fail to load and:

service https status    

Shows that https is stopped.

When using:

service httpd restart    

I get this error:

(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
no listening sockets available, shutting down
Unable to open logs

What could be causing apache to do this?

What happens when you reboot the machine? That is the very first thing you should do in a case like this to see if that clears things up. – JakeGould Nov 15 '13 at 22:42
When you see that error run netstat -nap | grep ''. Look at the far right column which will contain the PID/process that is bound. I've seen this happen when doing a restart sometimes. You may have better luck doing service httpd stop;sleep 1;service httpd start – yoonix Nov 15 '13 at 22:45
The -l option is handy in this situation as netstat then only lists listening ports. Also you must run it as root for the -poption to work. – Ladadadada Nov 16 '13 at 11:02


    netstat -antu|grep 80
    lsof -i -n -P|grep 80

Apache seems to be using a iPv6 address that is taking port 80, can I have some help and fixing/removing that function of it so it only uses iPv4? httpd 10975 root 4u IPv6 1010994 0t0 TCP *:80 (LISTEN) – Mr_Galaxy_97 Nov 15 '13 at 22:52

You probably have a line in your httpd.conf that looks like:

Listen 80

try changing it to:


which will make it listen on all IPv4 addresses. Recent apaches will listen to (only) IPv6 by default if you just have Listen 80 , if the system has as valid IPv6 address (even just a link local self-assigned address).

Don't the messages about not being able to bind to [::]:80 and kind of imply that it can't bind to any IPv6 or IPv4 address ? – Iain Nov 23 '13 at 8:05
