since I’ve decided to run my discourse in the old way,I upgrade the source to the latest version,and it require ruby with version 1.9.3 above,so I switched to using rvm and followed this guide[enter link description here](https://github.com/lee-dohm/install-discourse)
Everything seems go fine but only "502 Bad Gateway"error appears when I tried to visit my forum.So what should I check?Thanks a lot.

Unless you need to use 1.9.3 for something else, try using Ruby 2.0.0. Also, this guide still works as of the other day, so maybe give that a shot? [https://github.com/discourse/discourse/blob/master/docs/INSTALL-ubuntu.md](https://github.com/discourse/discourse/blob/master/docs/INSTALL-ubuntu.md)

We regret that we can only support the Docker based installs here. Sorry.
