Keepalived uses the IP Virtual Server (IPVS) kernel module to provide transport layer (Layer 4) load balancing, redirecting requests for network-based services to individual members of a server cluster. IPVS monitors the status of each server and uses the Virtual Router Redundancy Protocol (VRRP) to implement high availability.
The configuration file for the keepalived
daemon is /etc/keepalived/keepalived.conf. This
file must be present on each server on which you configure
Keepalived for load balancing or high availability.

documentation, and the versionkeepalived(8) and
keepalived.conf(5) manual pages.
