mongrel processes I’m using mongrel_cluster . Now, I want to run
Mongrels on Machine’s B and C (ie Cluster 3 Mongrels in three
different machines). Is this possible? If possible then, please

Hi Santhu,

You might want to signup for the Rails-deploy group on google. It’s a
new
group formed to address just this kind of question.

Hi Santhu,

I think what Darushin explained would be the most common setup.

Quick search turned this up:
http://blog.innerewut.de/articles/2006/04/21/scaling-rails-with-
apache-2-2-mod_proxy_balancer-and-mongrel

We have a hw load balancer and are load balancing apache processes and
will soon load balance all the monrels using this too. Outside request
→ LB → [Apache 1, Apache 2, etc] → LB → [Machine 1 Mongrel 1,
Machine 2 Mongrel 1, etc].

Hi Darushin/Bill ,

First of all thanks for the valuble information. I’m looking for some
explicit steps required to set up a distributed “mongrel cluster [I mean a multi machine set up]” (I’m not not using capastrino :frowning: for
the time being) . Please help me
Best regards,
Santhu

Hi Santhu,

I’m replying just so you don’t think I’m ignoring you. There are folks
here
on this list, like Darushin, who can help. It’s way over my head,
though.
If you don’t find the help you need here, the experts are at
rails-deploy.

Best regards, and good luck,
Bill

I think that guide should help you get your hardware going. If you have
issues post them and we will see what we can do.
