Install GeoIP for Apache and PHP/PHP-FPM on Centos
GeoIP is a C library that enables the user to find the country that any IP address or hostname originates from. It uses a file based database that is accurate as of February 2009. This database simply contains IP blocks as keys, and countries as values. This database should be more complete and accurate than using reverse DNS lookups.

yum install GeoIP{,-devel}
