I have a need to deploy a High Availability Load Balanced reverse proxy solution. We have a back end web service that requires resilience. To achieve this I’ve been looking at Nginx and Keepalived. The Nginx Plus product appears to contain high availability support – but we’re in the realms of zero budget and open source/community supported products. The front end reverse proxy I’ll use is Nginx, but it could be anything. The clever part is going to be using keepalived to pass a single IP address between two servers. Find yourself three fresh unused IP addresses. One for each server and one to share as the HA address. eg. 192.168.1.224, 192.168.1.225, 192.168.1.226 First I installed a pair of Debian Stretch servers (loadbal01, loadbal02) and prepared them as per my usual minimum build with sshd and pretty much nothing else. I used the addresses .225 and .226 for my servers. I’ll use .224 for the “virtual” HA address. Just to test before converting Nginx into a reverse prox...
