nginx bans an IP from accessing the site

There is an IP that is spamming the website, and I want to block this IP to prevent him from opening the website. After checking the information, many people on the Internet said that /etc/hosts.deny can be implemented. In fact, this is not possible. I don’t want to use iptable, it seems too troublesome. Directly check how nginx blocks IP access.

First create the following configuration file and place it under the conf directory of nginx, named blocksip.conf:

deny 4.4.4.4 //This is the IP that nginx wants to ban

Save it.

Add: include blocksip.conf to the nginx configuration file nginx.conf; and then restart nginx, and it will take effect. When a blocked IP opens a site, it will prompt:

403 Forbidden

blocksip.conf: There are many formats. You can configure only allowed IP access or IP segment access:
deny IP;
allow IP ;
# block all ips
deny all;
# allow all ips
allow all;
The network segment is written like this: 192.168.1.0/24.

The above introduces how nginx prohibits a certain IP from accessing the site, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
