Hi,
I'm building a cluster based on raspberry. This cluster contains 4 nodes (raspberry). Three of them each host an Apache server, whose purpose is to deploy a Web application designed in PHP. The fourth, I would configure it as a reverse proxy and load balancer at the same time with NGINX. The three Apache nodes have a static IP address of the form 192.168.0.x, so the problem is that the raspberry has only one rj45 interface. How to configure the fourth node (reverse proxy and load balancer with nginx) with 2 ip addresses, one from my router and the other in the same network as the 3 nodes Apache (192.168.0.x)? Will it be necessary to add a rj45 interface? Or is there another alternative? Thank you in advance for your answers.
