What is the use of nginx's GeoIP?

The GeoIP module in Nginx can block requests for specified IPs, but it is not compiled by default. After opening it, we only need to download another IP rule and configure it in the Nginx server GeoIP module to intercept specified country IP.                                                                                                                                                                                                                                                       ​ I took the time to research this information. The best method found so far is to use Nginx's GeoIP module to achieve region identification. Then configure the ISO name of the relevant country and prohibit access. Record the relevant process. Compile the GeoIP component

The free version of the database provided by maxmind can already meet the needs. Before using the database, you need to compile the GeoIP component first:

wget http://geolite.maxmind.com/download/geoip/api/c/GeoIP-1.4.8.tar.gz
./configure
make
make install

Download IP library

Download the IP packet from maxmind and unzip it. This is the country’s ip data packet:

wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
gunzip GeoIP.dat.gz

This is the city’s ip data packet:

wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoLiteCity.dat.gz

After executing the above command, you will get GeoIP.dat and GeoLiteCity .dat files. Copy these two files to Nginx's conf directory.
