Im running a 5 node gentoo LVS apache cluster. |
2 |
It has full hearthbeat failover (over ip), and ldirectd functionality. |
3 |
|
4 |
Im using a tweaked direct route setup in which there are two directors, |
5 |
checkup on each other trough hearthebeat. which redirect packages to 3 other |
6 |
nodes, and localnode. |
7 |
All nodes have a full internet connection though, which allows for phased |
8 |
setup. (no need to setup the whole portage / binary replication thing first. |
9 |
each node can keep himself up-to-date.) |
10 |
|
11 |
If we're going to setup a nice wiki tut, il put up my configs aswell. |
12 |
ironically i used a win2k + LVS tutorial to get my system to work as it |
13 |
should. |
14 |
|
15 |
The whole concept of all those LVS monkey releases is something i didn't |
16 |
really grasp at first, since gentoo doesn't install the packages like that, |
17 |
but just keeps them all up to dat trough portage, which is very different to |
18 |
what the LVS docs are talking about. |
19 |
|
20 |
The one thing im still strugling with is a way to share and replicate a set |
21 |
of stable files, they don't change often, but when they do, each cluster |
22 |
node ought to be updated. |
23 |
|
24 |
I had an extra NFS server for this, outside the cluster, connected over |
25 |
local ip's, but the one node i has setup to talk to that (with enough swap |
26 |
space to keep a local cache i figured), crashed on me,making me damn |
27 |
reluctant to try it out on the rest. |
