How to setup nginx reverse proxy for apache?

Question

Nginx

There is a site to turn on apache. Installed nginx there. centos system. I can't set up nginx as a reverse proxy. error 502 comes out. the site itself at the local address works with a bang (192.168.1.3:8080). at 192.168.1.3:80 the nginx test page comes out.
