Apache2 / MySQL / Mongrel on separate machines

Rails
1

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

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.

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.
