Synchronizing a website across many servers

How do I do that effectively?

[FormosaKing]

I'm currently trying to run 5x instances of the same website on load balancers running Apache2 on CentOS. Currently, I either commit changes to subversion and update on each site manually, or I use rsync.

Ideally, I want to make a change to certain files on one server and have them show up live on the rest.

Since most of the files don't change, I was thinking of having a single server with all the files that do change. and have the rest query that server once in a while to keep everything up to date. Subversion + a cron job sounds like it may do the trick.

Any suggestions? Thanks!

Use cron to schedule rsync from the 'master' server to your 'slaves'?
