=========================

Cause:
This problem is caused by another service listening to TCP/IP port 80.

Solution:
1. OK $ sudo fuser -k -n tcp 80
     OK $ sudo /etc/init.d/httpd  start
2.  Change the listen port in the httpd config file to 81, by doing this we want to see which service is using port 80.
     just do the following command as root :
#netstat -tlp
after running the command.
Active Internet connections (only servers)

tcp 0 0 :::111 :::* LISTEN 1310/rpcbind
tcp 0 0 :::80 :::* LISTEN 2593/httpd
tcp 0 0 :::81 :::* LISTEN 2593/httpd

now we know that port 80 is utilised by another service, so locate and change system-config-httpd.conf: system-config-httpd.conf system-config-httpd.conf. all of this, restart httpd:
/etc/init.d/httpd start

3.  Third solution is to change binging address in your httpd.conf  like this:
Listen 127.0.0.1:80 ( that means:  instead of  Listen 0.0.0.0:80)
