Proliferate commands across nodes?

Hi folks.

I've been a developer for far too many years, but know very little of unix. I have setup a very inexpensive cluster of 6 raspberry pi nodes so I can play around with multi node programming. This is only for fun, but I want to learn properly, else what's the point?!

Setup can be a bit of a ball ache with proliferating code and commands.

Could you please suggest software that will allow me to send commands to node 1 and have that proliferated to the other 5? I have searched for this and found a few possibilities, most do a lot more than I need and the one that looks perfect (fabric) doesn't install in Raspbian, no idea why.

I'm sure I could write a bash with ssh and accomplish the basics, but I like the idea of asynchronous replies which I think is going to be a depth to far.

Any suggestions welcome, and if you have an opinion of one thing over another please let me know why.

Many thanks.

4S-BACKEND_SETUP(1J)						      4store						      4S-BACKEND_SETUP(1J)

NAME

     4s-backend-setup -- Create a new 4store KB

SYNOPSIS

     4s-backend-setup kbname [--node node-number] [--cluster cluster-size] [--segments segment-count] kb-name

		      --node  Number of this node in the cluster, values range from 0 to cluster-size - 1.  The default is 0.

		      --cluster
			      The number of nodes in the cluster.  The default is 1.

		      --segments
			      The number of segments in the cluster. The default is 2. We recommend one for each CPU core in the cluster as a good
			      starting point. Higher numbers tend to consume more resources, but may result in increased performance.

NOTES

     Once crated with 4s-backend-setup KBs should be started with 4s-backend(1)

SEE ALSO

     4s-query(1), 4s-size(1), 4s-httpd(1), 4s-backend(1), 4s-delete-model(1)

EXAMPLES

     $ 4s-backend-setup --node 0 --cluster 1 --segments 4 demo

     Creates the indexes for a single-machine KB with four segments, named "demo".
