PS: I have done a lot of NGINX proxy tests before and forwarded port-based services, but they all ended in failure. This is the only method you can try.

In addition, servers that have NGINX installed may need to uninstall and reinstall, because the patching stage is done in the installation package. At least so far, I have not found a way to patch the installed nginx service. The README only introduces patching under the installation package.
The above introduces the Nginx configuration to implement reverse proxy and load balancing based on the TCP protocol, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
