@jarey I tried that cartridge and it wont install at all...check the issues.
Got it working!!!! (NodeBB that is) http://nodebb-paez.rhcloud.com/ names prolly gonna change to forum if that links doesnt work.
Try these two.....
https://github.com/icflorescu/openshift-cartridge-nodejs
https://github.com/transformatordesign/openshift-redis-cart
One problem I only just noticed trying to install nodebb was that nodejs wasnt actually finishing its compiling....that prolly caused a bunch of my probs...mainly the liwp not working.
That redis is at 2.8.13 so up to date and is forked off the one recommended.
