The VPS server blocks the IP address of a certain country from accessing the one-click script

Recently, some foreign IPs have been posting spammy external link comments to bloggers. There are a lot of them every day. I was thinking about how to only allow users from mainland China to access the website. After some searching, I found a way to directly block them. A script for a certain country can be blocked by blocking the IP of the country that sends spam comments. Let’s share the installation tutorial of this script.
