The OpenStack Compute and Image services work together to provide access to virtual servers and images through REST APIs. The Identity Service provides a common authorization layer for all OpenStack services. You must use the Identity Service to install the OpenStack Dashboard, which offers a web-based user interface for OpenStack components. The OpenStack Object Storage service provides not only a storage method for virtual images but also a cloud-based object storage system with a REST API to store and retrieve objects such as images or videos. This walk-through starts with Compute and related services and we will add Object Storage at a later date.
This installation walk-through goes through a very specific path for installing OpenStack on Ubuntu 11.04 or 11.10 with root access and specific configuration settings using MySQL for related databases. Here are the overall steps:
Select a set of packages for your repository.
Install the Identity Service (Keystone).
Configure the Identity Service.
Install the Image Service (Glance).
Configure the Image Service.
Install Compute (Nova).
Configure Compute with FlatDHCP networking using192.168.100.0/24 as the fixed range for our guest VMs on a bridge named br100.
Create and initialize the Compute database with MySQL.
Add images.
Install the OpenStack Dashboard.
Launch the Dashboard.
Add a keypair through the Dashboard.
Launch an image through the Dashboard to verify the entire installation.
