Hi
I installed Apache/2.2.13 (Unix) on CentOS 5.4. My prolbem is that when
I try to start and stop it using "sudo /etc/rc.d/init.d/httpd start /
stop / restart"
It gives me the following, I googgled a lot but could not really find a
solution.
1.Command : $ sudo /etc/rc.d/init.d/httpd start
Error Message :

Some other process is already running at port number 80. Use netstat -ltnp | grep ':80' to get the process name and pid.

Thanks Nilesh, netstat reveals the following :

tcp 0 0 :::80 :::* LISTEN 2056/httpd

Strange thing I notice is that start / stop / restart fails, but service is still started, I am just curious if service is failed to start (as error message explains) how come it is started at the first place?

To my view a command 'stop / restart' should kill a started process and free the port '80' and next initialization should get the port without any error.

My http configuration have 'Listen 80'

Not much into linux stuff. Forgive me if I am wrong somehere and correct me please.

Thanks for your help.
