CentOS Open a Port

I am trying to open port 80 & 443 to everyone.  My et/sysconfig/iptables looks like:

# Generated by iptables-save v1.3.5 on Tue Mar 20 19:14:47 2012
*filter

When i test the ports with a port query tool it tells me they are not open.  What did i miss?

Are you sure Apache is running when you run the port scan?

Do you have anything in /etc/hosts.allow or /etc/hosts.deny ?

/etc/hosts.allow or /etc/hosts.deny are both empty

Apache is not running

Start up Apache and run the port scan again.

What about IPTables and Firewall? Are they running?
JZeollaCommented:
Your syntax seems correct.  

First make sure you start up whatever is going to be connecting to port 80.  Then verify that the system is listening on port 80 using:
netstat --listen -an | awk '/LISTEN/ && /:80 / && /tcp/'

Now run your port scan.  Since it's a tcp port scan, it requires a response to be considered 'up' and therefore it needs to have traffic allowed in addition to a listening service on that server's port 80.
