Apache2 / MySQL / Mongrel on separate machines

Hi all, I have read and re-read the tutorials on mongrel clusters and have a question. Most, if not all, deal with having everything run on one box, locally. I would like to add more redundancy by having several boxes. Would I do this by editing the apache config as such:

<Proxy balancer://mongrel_cluster>   BalanceMember http://192.168.1.102:8000   BalanceMember http://192.168.1.103:8000   BalanceMember http://192.168.1.104:8000 </Proxy>

My ideal setup would be to have Apache2 run a box fronting all my mongrels, have a cluster of 2-3 mongrel servers running several instances of mongrel on each, and lastly have MySQL plugged into the ring. My aim would be to be able to add mongrel machines as I need to or replace if one goes out on me.

Doing this, what kind of conflict may I be facing? Also will capastrano work well with this also?

Any help appreciated!!! btw, I am using Ubuntu for this.

Yes, you have the idea correct with the above lines.

or replace if one goes out on me.

This is the setup I use and I would think it is fairly common.

You can use the deprec gem (lots of capistrano stuff tied together) which automatically generates all your configuration files etc for Ubuntu.

Great, thanks for the guidance.
