NginX: Load Balancing, Failover, and Geo Location (Part 3)

NginX: Load Balancing, Failover, and Geo Location (Part 3)

Okay we continue to the third part of this post title, on the previous part we use NginX as load balancer and failover, now we use NginX with Geo IP based to determine the best backend for the visitors to put, here is the illustration.

For instance, we have two backend servers located in UK and DE, then we put the visitors from United Kingdom to the UK backend, visitors from Germany to DE backend, and the rest will be divided into those two backend servers, let’s deal with it.

I assume you have installed NginX in your frontend and two backend servers, you can check the previous post for NginX installation. This GeoIP based location needs GeoIP database for the frontend server to determine where to put the visitor, so first we download and extract Lite version of GeoIP database from Maxmind with geo2nginx.pl script from http://markmaunder.com.

wget https://serversreview.net/pkgs/txt/geo2nginx.pl
chmod 755 geo2nginx.pl
wget http://geolite.maxmind.com/download/geoip/database/GeoIPCountryCSV.zip
unzip GeoIPCountryCSV.zip
./geo2nginx.pl < GeoIPCountryWhois.csv > geo.conf
mv geo.conf /etc/nginx/

GeoIP database has been added to NginX directory, now to the configuration, here is the example of main configuration

Yeah guys, let’s talk about this post title, really it is interesting, i mean for me this is very interesting :p.

So the first thing you need to do is this, do not put your site in shared / reseller hosting. Why? Because in shared hosting, your site is not alone, there are so much neighbor in it, and your site could be exploited from those neighbor, for instance bug in script. Another thing is you cannot get root access from shared hosting, your creativity is limited by non-ssh regular user assigned to your account. So take a look at LowEndBox and get a vps for your shared hosting substitution.

Nuff said for the appetizer, let’s get to the main course. The simplest failover method for website is round robin dns, the illustration would be like this:

where the server has been assigned with two or more ip addresses, so if end user fail to access the server with the first ip address, it will be routed to the second ip address. To use that settings, you simply
