Scripting the build of OpenDayight Controller under CentOS
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:

Once up and running, it’s pretty trivial to point something like an HP switch at the controller. For an HP5400, just decide what VLAN(s) you want to use OpenFlow on. I chose 999 as my test VLAN.
sw-5400-of# conf t
sw-5400-of(config)# vlan 999 name test-openflow999
sw-5400-of(vlan-999)# untagged A3-A4
sw-5400-of(vlan-999)# exit
sw-5400-of(config)# openflow vlan 999
sw-5400-of(openFlow vlan-999)# enable
sw-5400-of(openFlow vlan-999)# controller "tcp:10.17.4.22:6633"
sw-5400-of(openFlow vlan-999)# exit
sw-5400-of(openFlow)# exit
sw-5400-of(config)#
w-5400-of(config)# exit
sw-5400-of# show openflow
sw-5400-of# show openflow

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.
