How to make nginx and apache2 work on port 80 of the same interface?

Question

Nginx

Given: Ubuntu Server 14.04; Nginx; Apache2
There is an eth0 interface and a subinterface eth0:0. Both have different ip addresses.
There is Nginx, which listens on port 1935 and gives on 80 and 1935 ports eth0.
There is Apache2 which listens on port 8080 eth0:0.
Question: how to make Apache2 listen on port 80 eth0:0?
Any attempt to set port 80 does not let Nginx through. It is necessary to ensure their simultaneous operation on different ip, but on the same port 80.

Answer 1

Are you only setting the port or ip:80 in apache?
You need to hardcode which ip:port to listen to both nginx and apache, otherwise they will listen to all available ip.
