OpenSSI cluster


Install howto for debian sarge (3.1): (really good explanation about howto progress after mastersetup - suggest following this after the below link to setup openssi on etch)

Install howto for debian etch:

Master setup


deb etch main contrib non-free
deb-src etch main contrib non-free

deb etch/updates main contrib
deb-src etch/updates main contrib

deb ./
deb-src ./

deb etch-backports main contrib non-free

There are 2 ways to setup a master distribution load:

  • SMP

- Which will try to fill up a load on one node and then relay to the others - all nodes are simply seen as another CPU and for the system it thinks it's just one huge singular system. This will accept and return queries/data from the same ip.

  • IP server

- This distrubutes loads according to the scheduler chosen and thus try to distribute load evenly across all nodes. This will receive on a seperate IP specified in cvip.conf and return data directly from the nodes (unless NAT is choosing as routing)

SMP setup

  • /cluster/etc/loadlevellist

Must have all the seperate instances of applications which has to run independently - ie clamav and amavisd-new if it's a mailscanner cluster:


IP server (ip loadbalancing)

  • /etc/cvip.conf template
<?xml version="1.0"?>
