Keepalived User Guide

This guide walks through the concepts behind Keepalived, how to install it and how to configure load balancing and high availability. It started life as the original Sphinx user guide and has been refreshed for this site, with the configuration details aligned to the current keepalived.conf(5) reference.

Some operational examples remain historical illustrations. For the exact keywords and defaults of your release, always rely on keepalived.conf(5), and for current packages see the Download page.
