Deploying a small OpenStack test environment using Crowbar

Contents 1 Introduction 2 Requirements 3 Steps 4 Troubleshooting

Introduction

This tutorial describes how to get a small OpenStack environment up and running for testing purposes inside Crowbar.

Requirements

• A running crowbar system. See [here] for more details.
• You should be on a recent Crowbar with the newer UI. The build should be no older than Sep 27 2011
• 8GB Ram in your virtual environment (You might be able to get away with 4 if you're doing nothing else)
• For debugging and following along with what Crowbar's up to, log into your crowbar server and tail the Rails logfile:

tail -f /opt/dell/bin/crowbar_framework/log/production.log

Note: If you're in development mode, tail the dev log.

Steps

• Start up your crowbar node, and clear out all clients and nodes.
• Spin up a new node.
  • Click on Barclamps -> Mysql -> Create Proposal (Feel free to give this a different name.)
  • Make sure your new node is set as the 'MySQL Server' and Apply it
  • Wait until the server is running.
  • Click on Barclamps -> Glance -> Create Proposal
• Spin up your second node. Give this one 2GB Ram
  • Once that node is up, go into your prior MySQL proposal and add your new node as a mysql client and apply.
  • Create a Proposal for Nova.
  • Put your new node in Nova-Single-Machine, with no other nodes in any other role.
  • If you're running in a virtual environment, set your libvirt_type to 'qemu'
  • Apply the barclamp.

Congratulations, you now have a running, working deployment of OpenStack.

Bigger install: 5 nodes - allocate OS to each node

1. Prob mysql pre-first
2. Glance on node 1 first
3. Nova
   1. Master on node 1
   2. multi-compute on 2 other nodes
4. Nova-dashboard on node 1
5. Keystone on node 1 (Dashboard doesn't work without it)

1. Nova Dashboard
2. Keystone

Troubleshooting

• Check the nodes inside the Crowbar ui. Your MySQL/Glance server should have the appropriate roles applied. If there is no glance server, Nova won't install.
• Clean nodes are important. If you're installing over older nodes, make sure they're completely wiped clean. Delete all prior proposals and node data in both Crowbar and Chef Server.
• The Mysql-client role via the barclamp should provide a node attribute 'mysql-server'.If you're having trouble with this being generated, you can create the attribute directly on the node in chef. The value should be the address of your mysql-server node.
