Shell script to update global Maxmind GeoIP databases. This script can be run via cron.

update_geoip_databases.sh

#!/bin/bash

DAT_DIR=/usr/share/GeoIP
DAT_URLS="http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz"

for FILE in $DAT_DIR/*.dat; do
    cp $FILE $FILE.bak
done;

for URL in $DAT_URLS; do
    FILE=${URL##*/}
    curl $URL | gunzip > $DAT_DIR/${FILE%.gz}
    #echo $URL $DAT_DIR/${FILE%.gz}
done;

Thanks, @lukenm!

Super, thanks!

I recommend using http://geolite.maxmind.com/download/geoip/database/GeoIPv6.dat.gz instead of GeoIP.dat.gz since it includes both v4 and v6 IPs.
