On this post brief outline of install or update the latest GeoIP Country on Unix/Linux.

Using wget command can download the Geolite file 

# wget -N http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz

Once you have downloaded the database need to uncompress that file using gunzip command,
# gunzip GeoIP.dat.gz

Note : -N option to only download if the file has been updated

Find out location of geoip database,
#  whereis  geoip
geoip: /usr/local/geoip

#  cd /usr/local/geoip/share/GeoIP
# cd /Geo-Ip-Path/share/GeoIP

Before changes take a backup a existing GeoIP database
# cp GeoIP.conf GeoIP.conf_bak

# cp /root/GeoIP.dat .

Once you have updated the GeoIP.dat file need to restart named.

netstat -anp | grep named
