[lvs-users] Questions about getting started with LVS

Hi - I just came across LVS and it looks like a great package. However I am a total Linux newb (coming over from a decade+ on Windows) and I must admit this is way way over my head so I'm trying to get my arms around it. A few questions if you would be so kind:

For reference I am using Fedora 8 core on i386.

1) According to the LVS web site and changelog it looks like the latest released LVS software is 3-4 years old. Am I reading this right? The project seems very popular so I am thinking there may have been several updates since 2004/2005? Am I missing something?

2) I have absolutely no idea how to go about getting this installed and up and running on my Linux box, really. This is despite having read through the documentation.

It looks like I am supposed to start by getting "The IP Virtual Server Netfilter module for kernel 2.6". My my Linux box as root I did wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24-6.src.rpm to get this software.

>From there I really had no idea of what to do next. The Compiling ipvsadm on different Linux distributions at wiki is talking about RedHat 3 and 4 which no longer seem applicable for those on Fedora 8.

Unfortunately this is all just way way over my head. Is there a complete idiots guide to getting up and running with LVS on Fedora 8?

Thanks so much!

this is the level you need to be before we'll help you.

LVS is distribution neutral. If you want to do it in Fedora,
then you'll have to handle the Fedora-isms.

OK, go on then :)

Great. It's all available to you as part of the distro.

You have to understand that there are two parts to LVS - the kernel
modules (which actually do the work) and the userspace parts (which
allow you to configure it). The kernel modules get updated as and when
necessary - you'd have to look at the changelog at kernel.org to see
when that's happened, but the most recent changeset was put into 2.6.24
in November 2007.

You already have the kernel modules - Fedora includes them. You need to
install ipvsadm using Yum:

yum install ipvsadm

That gets you a basic set of tools with which you can make a lot of
stuff happen. If you want high availability, health checking, monitoring
and so on then you need some other tools to do that for you:

keepalived
ldirectord
heartbeat

to name but three.
