Jon Langemak has a great write up on building the OpenDaylight controller under CentOS. Since I’ll have to do this a bunch of times, I though tI’d take what he so generously put online and build a very rudimentary script for deploying ODC under CentOS. The prerequisites are that you already have an account and ssh key at the OpenDaylight GIT repo and that you disable SELinux. Here is the script:``` #!/bin/bash

From here we can see the box in the openflow controller.    

  I’m still having some issues pushing flows, I’m sure I can work it out but here is a quick screencast of me trying to push a flow.  More posts will be added as soon as I can get the flows to push correctly. I suspect it is user error and I just need to read the docs.  More to come for sure.  This controller is very, very slick.
