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.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description. Line
|
||||
# up the first '|' above the ':' following the base package name, and the '|' on
|
||||
# the right side marks the last column you can put a character in. You must make
|
||||
# exactly 11 lines for the formatting to be correct. It's also customary to
|
||||
# leave one space after the ':'.
