Install the GeoIP development package

 

Install mod_geoip2 by fetching the latest version with wget. To check the latest version, take a look here first:

I’m installing 1.2.10 here with this, but replace the code in lines 1, 2 and 3 here with their latest version:

If you haven’t got apxs then you’ll need to install httpd-devel.

Be aware that this overwrites httpd so backup your server in case this fails or you get strange results.

 

If this fails with “Error: Nothing to do”, then it’s fairly common. You’ll probably find that /etc/yum.conf is blocking the installation. We can get around this by either editing the configuration file or typing:

 

You should now have mod_geoip2 installed on your server!
