Detailed explanation of Alibaba Cloud security rule configuration

Two days ago, I took advantage of the Double 11 shopping festival and bought an ECS (server) on Alibaba Cloud. I just configured an nginx and tried to access it as shown below, but found that it could not be accessed.

It turns out that Alibaba Cloud Server needs to configure security rules for security reasons. If you do not set security rules for the port, the browser cannot access it.

So how exactly are security rules configured? See below for details:

(1) Log in to Alibaba Cloud, find [Cloud Server ECS], and click;

(2) Click the number behind the cloud server;

(3) Click [Security Group], find [Configuration Rules] for the corresponding server instance, and click;

(4) Click [Add security group rule]

(5) We take port 80 as an example to configure so that all IP addresses can access port 80;

(6) Then after a while of configuration, one more rule can be added.

(7) At this point, our nginx can be accessed.
