nginx problem accessing virtual hosts

[Sc0rian]

Hello all,

I have nginx running on port 81. I can access all my sites (including virtual ips) on the port 81. However when I forward the traffic from port 80 to 81, the virtual ips have a message saying "Apache is running normally". However I still can access the sites on the port.

All server ip traffic is fine.

Hello,

I've got experience with building front-end & back-end architecture with Nginx and Apache. And I can sure fix it very quickly if you give me root access to your server. Of course it will cost you some money. If you have time to discuss it here on the forums, you need to show your real nginx config with real IPs (you might want to hide some digits there), and other data. Just PM for a quote or post here requested config and results of

ps aux | egrep "apache|nginx"

and

netstat -an | grep LISTEN | egrep ":80|:81"

thanks for the reply and offering your services. I'd rather learn and fix it myself

any ideas ?

I don't see what can cause such a behavior in your case, and don't have time to go through the guide a link to which you gave. Note though I use NGINX with Apache... my configuration differs, and I don't use firewall to forward requests from Apache to NGINX (I used to do so many years ago on FreeBSD). So you should either refer the question to the author of the guide, or wait for somebody's else answer here.

Note, I still can find time and fix you issue in terms of a commerce service.
