FYI:
http://www.freehao123.com/openshift-wp-dz/
I chose these cartriges:
use shell to connect
[mssssssssseng.rhcloud.com 5720d2ssssssssss001b]\> ls app-deployments app-root git jbossews mysql phpmyadmin
app-root/runtime/repo
[msssssssssng.rhcloud.com repo]\> ls pom.xml README.md src webapps
then I can mkdir and do somethings under this directory.
But How To Build? Still Studying...
