Question

Ask how to forward the addresses of multiple servers on nginx and solve cross-domain problems

Answer 1

There are relevant configurations in the nginx configuration file
The http part can be configured with upstream
upstream phpserver {
server 127.0.0.1:9000 weight=10;
server x.x.x.x.:xx weight=10;
server x.x.x.x.:xx weight=10;
server x.x.x.x.:xx weight=10;
}
Just configure the server IP and service port
