What is Keepalived ?
|
|
|
|
The main goal of the keepalived project is to add a strong & robust
|
|
keepalive facility to the Linux Virtual Server project. This project
|
|
is written in C with multilayer TCP/IP stack checks. Keepalived
|
|
implements a framework based on three family checks: Layer3, Layer4
|
|
& Layer5/7.
|
|
|
|
This framework gives the daemon the ability of checking a LVS server
|
|
pool states. When one of the server of the LVS server pool is down,
|
|
keepalived informs the linux kernel via a setsockopt call to remove
|
|
this server entrie from the LVS topology. In addition keepalived
|
|
implements an independent VRRPv2 stack to handle director failover.
|
|
So in short keepalived is a userspace daemon for LVS cluster nodes
|
|
healthchecks and LVS directors failover.
