Multi-node Openstack

Hi,

I'm having trouble trying to deploy Openstack on multi-node servers. For example, if I have 3 physical servers and want to have a cluster of openstack. Can anyone share any good material to help me with that? I've found many on internet but some of them don't explain very well.
Also, can you have 3 nodes exactly the same ? Working as compute node, storage and controller ?

Thanks

    What method are you using to deploy?

    Packstack for now.

    So in your answers.txt file you would add the IPs for the multiple machines like as follows:CONFIG_NOVA_COMPUTE_HOSTS=10.15.0.2,10.15.0.8

    Is it a problem to have storage, network and compute in the same node ? For example, having 3 nodes with all those features ? Do I need to configure passwordless ssh access between the machine before packstack to make sure it can connect to those hosts and add them to openstack?

    You will need passwordless ssh between the servers, network should be on the controller if you're combining with some aspects on the compute. You can have storage on a shared node.

    That's great. Thank you for that Amy!

    That worked like a charm! Thank you for the help. I managed to create a 3 node one having all the features and being the controller and the other 2 with compute, networking and storage.
