The architecture mode is nginx -> haproxy -> apache
How does haproxy get the real IP passed by nginx?
Of course nginx adds a field to the http request header and forwards the real address to the backend. What are you thinking about?
It’s very simple. Just add the following command in the configuration optionsoption forwardfor except 127.0.0.1
