nginx: Install GeoIP Module For Country / City Level Geo Targeting

by

To install the GeoIP module for country or city level geo-targeting in Nginx, you can follow these steps:

  1. Install the GeoIP library: You can install the library using your operating system’s package manager. For example, on Ubuntu, you can use the following command:
sudo apt-get install libgeoip-dev
  1. Download the GeoIP database: You can download the GeoLite2 City or Country database from MaxMind’s website. The database provides information about the geographical location of IP addresses.
  2. Compile Nginx with the GeoIP module: To compile Nginx with the GeoIP module, you need to pass the --with-http_geoip_module option to the ./configure script when compiling Nginx from source. For example:
./configure --with-http_geoip_module
make
sudo make install
  1. Configure Nginx with the GeoIP module: After you have compiled Nginx with the GeoIP module, you need to add the following configuration to your Nginx configuration file to enable the module:
http {
geoip_country /path/to/GeoLite2-Country.mmdb;
geoip_city /path/to/GeoLite2-City.mmdb;

server {
...
location / {
if ($geoip_country_code = "US") {
# US visitors see this content
}
...
}
}
}

In the example configuration above, you set the path to the GeoLite2 City or Country database using the geoip_city or geoip_country directive, respectively. You can then use the $geoip_country_code variable in your Nginx configuration to make decisions based on the visitor’s country.

After completing these steps, you should have the GeoIP module installed and configured for use in Nginx.
