Damnit, this one catches me every time.  I setup new cloudserver instances so infrequently that it never hits muscle memory.  Open up that damn firewall port 80!

Edit /etc/sysconfig/iptables:

vi /etc/sysconfig/iptables

Add the following line

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

Save and restart iptables.

service iptables restart

I’m not sure if it is CentOS or Rackspace that is locking down the instances. I do know that I don’t have to do this for my local CentOS machines.
