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

I was getting following error while starting apache
============================

CT-5080444-bash-4.1# /etc/init.d/httpd start

Starting httpd: (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

 
==============================

To fix this issue:

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

========

root@srv2 [~]# netstat -tulpn| grep :80

If port 80 is bind to httpd, kill all process:

  

root@srv2 [~]# killall -9 httpd

Now start the httpd:

root@srv2 [~]# /etc/init.d/httpd start

Also make sure you are root while starting the httpd.
