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.
