how to configure 2 droplets with HAProxy + keepalived
About that response by a DO member team:
“If your load balancer went down in the environment described in this article (1 droplet as HAproxy + 2 droplets as webservers), your site would become unavailable. The easiest way to avoid having the load balancer be a single point of failure is to set up active/passive HAProxy pair. This would require two HAProxy servers and a virtual IP that can float between the two servers. The active HAProxy server would handle all of the requests unless it went down, at which point the passive HAProxy server would take over the requests.”
Can I have a virtual IP that can float between the two servers with Digital Ocean?
How can I configure this?
I have two droplets with active/passive HAProxy pair + keepalived, but I don’t know how to set up the Virtual IP.
