How To Create Reverse Proxy On Server B And Redirect To Server A

Hey there -

While I haven't tried to do this myself, I wanted to give you some resources that should be able to help you out.

First off, we have a guide that shows you how to set up reverse proxy with Nginx:

Use Nginx Reverse Proxy

Also, here's Nginx's documentation:

Nginx-Reverse Proxy

We also have another post here in the Linode Community that goes into it a bit deeper and discusses using the Nginx reverse proxy for an outside resource - which may be what you're trying to do:

Reverse-Proxy for Outside Resource

I hope this helps!

This is relatively straight forward to do.

As @rgerke highlighted, this is called reverse proxying.

A sample config would look something like this (this is a site using SSL, so the extra bits are for the SSL):

server {
  listen 443 ssl;
  server_name server-b.com;
  ssl_certificate /etc/ssl/certs/server-b.crt;
  ssl_certificate_key /etc/ssl/certs/server-b.key;

  resolver 127.0.0.53;

  location / {
    proxy_pass https://server-a.com$uri$is_args$args;
  }
}
