GeoIP Block NGINX Ubuntu 20.04

Block or filter IPs based on location in Nginx (tested on 1.18.0) on Ubuntu 20.04.

Install Nginx modules

To make use of the geographical filtering, we must first install the Nginx GeoIP module as well as the GeoIP database containing the mappings between visitors’ IP addresses and their respective countries. To do so, let’s execute:

$ sudo apt install libnginx-mod-http-geoip geoip-database
