Enhance Linux Virtual Server with a reliable keepalive feature for uninterrupted and efficient connectivity.
Keepalived for Linux is a powerful tool that aims to enhance the keepalive functionality of the Linux Virtual Server project. Written in C, this project boasts multilayer TCP/IP stack checks with a framework based on three family checks: Layer3, Layer4, and Layer5/7. With these checks, the daemon can efficiently monitor the state of an LVS server pool.
When one of the servers in an LVS server pool goes down, Keepalived informs the Linux kernel through a setsockopt call. This results in the removal of the server entry from the LVS topology. Additionally, Keepalived also implements an independent VRRPv2 stack to handle director failover.
Overall, Keepalived is a userspace daemon that offers robust health checks for LVS cluster nodes and LVS directors failover. If you are using a LVS director to loadbalance a server pool in a production environment, Keepalived is the tool you need to ensure a stable and reliable solution for health check and failover.
