PS: A lot of NGINX proxy tests have been done before, and port-based forwarding services have all ended in failure. only this method can be used.
Another server with NGINX installed may need to be uninstalled and reinstalled because it is played in the installation package during the patching phase. at least so far, I have not found a patch for the installed nginx service. README only introduces patching under the installation package.
The above describes how to configure Nginx to implement reverse proxy and load balancing based on the tcp protocol, including some content, and hope to help friends who are interested in the PHP Tutorial.
