Topic: Configure and Start Mongrel Cluster for a Simple Installation
Topic type:
The steps necessary for getting a Mongrel cluster up and running in the context of a simple installation as outlined in the installation guide.

Important Note: This step assumes that you are logged in as the user who will be running your Kete. For demos and development this is likely your normal account, for production this is the "kete" account if you have followed the conventions laid forth in the last step.
Configure and start your Mongrel Cluster
You have to configure your Mongrel Cluster (and Nginx) before your Kete application is ready to answer web requests.
We designate which ports our mongrels will be listening on by the "-p" argument, in this case 8000. The -N option specifies how many mongrels to run in your cluster. For development, only one mongrel is necessary, so we put "-N 1" and only port 8000 is used. For demos or a small traffic site, specify "-N 3" and ports 8000, 8001, and 8002 would be used. Make note of the ports you are using for your cluster. You will need them when configuring the Nginx web proxy.
$ cd ~/apps/your_app
$ mongrel_rails cluster::configure -p 8000 -N 1(if you are configuring mongrel for production environment add -e production)
This will write a configuration file to ~/apps/your_app/config/mongrel_cluster.yml.
To start your Mongrel Cluster, use the following:
$ mongrel_rails cluster::start # assuming you are still in ~/apps/your_app directoryYou can safely ignore warnings like "** Ruby version is not up-to-date; loading cgi_multipart_eof_fix"
Your Mongrel Cluster will now be running in the background. If you ever need to stop it, you can do this:
$ mongrel_rails cluster::stopLeave your Mongrel Cluster running before the next step.
If you would like your Mongrel Cluster to start at boot, see the Start Mongrel Cluster at Boot Appendix.
Next step:
Configuring Nginx

I've made a note in the topic above that you can safely ignore the "Ruby is not up to date" warnings from "mongrel_rails cluster::start". On Debian, I wouldn't update Ruby to any later version than what you have installed with apt-get, at least for now.
Things should work fine.
However, if you want to research this issue, please do, and comment here.
Cheers,
Walter
