Apache Address already in use: make_sock: could not bind to port 80 or 443 error and solution

Posted by Vivek Gite [Last updated: September 26, 2007]

Q. How do I fix an error, while restarting Apache ~ Address already in use: make_sock: could not bind to port 80?

A. If you are running SELinux disable temporary for port 80.

Apache Address already in use: make_sock: could not bind to port 80 error and solution

First make sure port 80/443 is not used by any other service or application with netstat command:

# netstat -tulpn| grep :80

If port 80 is bind to httpd, kill all process:
# killall -9 httpd

Now start the httpd:
# /etc/init.d/httpd start

Also make sure you are root while starting the httpd.

I have already used above commands but still the problem persist. When i use netstat then no pid/program name displays associated with it as below output.

netstat -tulpn | grep :80

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN -

Please help me in this situation what should i do.

you must sudo netstat or it won’t show you everything (sudo killall also)

Try to killall -9 php - this should solve your problem
