Missing nginx.conf or reinstall?

For some reason my ngnix.conf is blank. I tried modifying one from the source but not having much luck. Is there a sample nginx.conf I can use anywhere or do I just need to reinstall.

Also is there a good method to reinstall rockstor on the same box?

Looks like a yum reinstall rockstor did it for me along with killing nginx and restarting it.
I probably have to reinstall everything though since my rockons seem to have been messed up.
