How to open Alibaba Cloud server port

I recently bought an Alibaba Cloud server. After installing Nginx, it could not be displayed normally in the browser. After checking for a long time, after confirming that it was not a problem with the configuration file, I went online. The reason was found. It turns out that Alibaba Cloud servers need to configure open ports in the cloud console. The default open port of Nginx is 80. If you go there and configure it, it will cure the problem.
