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. diff --git a/network/keepalived/doinst.sh b/network/keepalived/doinst.sh new file mode 100644 index 0000000000..7062d561a6 --- /dev/null +++ b/network/keepalived/doinst.sh @@ -0,0 +1,23 @@ +config() { + NEW="$1" + OLD="$(dirname $NEW)/$(basename $NEW .new)" + # If there's no config file by that name, mv it over: + if [ ! -r $OLD ]; then + mv $NEW $OLD + elif [ "$(cat $OLD | md5sum)" = "$(cat $NEW | md5sum)" ]; then + # toss the redundant copy + rm $NEW + fi + # Otherwise, we leave the .new copy for the admin to consider... +} + +if [ -e etc/rc.d/rc.keepalived ]; then + cp -a etc/rc.d/rc.keepalived etc/rc.d/rc.keepalived.new.incoming + cat etc/rc.d/rc.keepalived.new > etc/rc.d/rc.keepalived.new.incoming + mv etc/rc.d/rc.keepalived.new.incoming etc/rc.d/rc.keepalived.new +fi + +config etc/keepalived/keepalived.new +config etc/keepalived/keepalived.conf.new +config etc/rc.d/rc.keepalived.new + diff --git a/network/keepalived/keepalived.SlackBuild b/network/keepalived/keepalived.SlackBuild new file mode 100644 index 0000000000..c0a4fd9f4b --- /dev/null +++ b/network/keepalived/keepalived.SlackBuild @@ -0,0 +1,108 @@ +#!/bin/sh + +# Slackware build script for keepalived + +# Copyright 2010 Nilton Moura, Rio de Janeiro, RJ, Brasil +# All rights reserved. +# +# Redistribution and use of this script, with or without modification, is +# permitted provided that the following conditions are met: +# +# 1.
