Nginx reverse proxy 502 bad gateway error

cruise · April 12, 2013, 6:24pm

Hello,

I am getting 502 bad gateway error while trying to setup nginx server as
reverse proxy server with caching enabled. Both servers are on seperate
machines, another server having apache web server.

Given below are my config files, please help me.

nginx.conf

Please note www.example.com is replaced with actual domain, and ip

I have done the lnmp installation using the script available here :

First of all, try the following:

Configure you error log at some sensible level, e.g. “notice”.
Reproduce the issue and look into error log.

If after the above steps you still won’t be able to resolve the
issue yourself, try asking here again with error log information
included.
