Why isn’t Apache on CentOS on a Rackspace Cloudserver Working?
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!
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.
