Hi,

I’m trying to install Ruby on Rails 2.0.2 with Mongrel, following the  
instructions here –  
[http://blog.codahale.com/2006/06/19/time-for-a-grown-up-server-rails-mongrel-apache-capistrano-and-you/](http://blog.codahale.com/2006/06/19/time-for-a-grown-up-server-rails-mongrel-apache-capistrano-and-you/).  
I install the gems successfully, but when I try and run the second  
command under “Configuring the Cluster”, I get the error:

!!! Path to config file not valid: config/mongrel\_cluster.yml  
cluster::configure reported an error. Use mongrel\_rails  
cluster::configure -h to get help.

What does that mean? The full command and output are below. Thanks,

- Dave

You need to run cluster::configure from within the root directory of  
your rails project.
