OpenStack is open source software for building public and private clouds. It is now a global success and is developed and supported by thousands of people around the globe; backed by leading players in the cloud space today. This book is specifically designed to quickly help you get up to speed with OpenStack and give you the confidence and understanding to roll it out into your own data centers. From test installations of OpenStack running under VirtualBox to automated installation recipes that help you scale out production environments, this book covers a wide range of topics that help you install and configure a private cloud. This book will show you the following:
How to install and configure all the core components of OpenStack to run an environment that can be managed and operated just like Rackspace, HP Helion, and other cloud environments
How to master the complete private cloud stack; from scaling out Compute resources to managing object storage services for highly redundant, highly available storages
Practical, real-world examples of each service built upon in each chapter, allowing you to progress with the confidence that they will work in your own environments
The OpenStack Cloud Computing Cookbook gives you clear, step-by-step instructions to install and run your own private cloud successfully. It is full of practical and applicable recipes that enable you to use the latest capabilities of OpenStack and implement them.
Chapter 1, Keystone – OpenStack Identity Service, takes you through the installation and configuration of Keystone, which underpins all of the other OpenStack services.
Chapter 2, Glance – OpenStack Image Service, teaches you how to install, configure, and use the Image service within an OpenStack environment.
Chapter 3, Neutron – OpenStack Networking, helps you install and configure OpenStack networking, including new features such as DVR.
Chapter 4, Nova – OpenStack Compute, teaches you how to set up and use OpenStack Compute along with examples to get you started by running OpenStack Compute within a VirtualBox environment.
Chapter 5, Swift – OpenStack Object Storage, teaches you how to configure and use OpenStack Object Storage along with examples showing this service running within a VirtualBox environment.
Chapter 6, Using OpenStack Object Storage, teaches you how to use the storage service to store and retrieve files and objects.
Chapter 7, Administering OpenStack Object Storage, takes you through how to use tools and techniques that can be used to run OpenStack Storage within data centers.
Chapter 8, Cinder – OpenStack Block Storage, teaches you how to install and configure the persistent block storage service for use, by using instances running in an OpenStack Compute environment.
Chapter 9, More OpenStack, explores other features of OpenStack such as Neutron's LBaaS and FWaaS services, Ceilometer, and Heat.
Chapter 10, Using the OpenStack Dashboard, teaches you how to install and use the web user interface to perform tasks such as creating users, modifying security groups, and launching instances.
Chapter 11, Production OpenStack, shows you how to use Ansible for automated installations and introduces you to tools and techniques for making OpenStack services resilient and highly available.
To use this book, you will need access to computers or servers that have hardware virtualization capabilities. In a typical small starter installation of OpenStack, you will need a Controller host, Network host, and Compute host. To run Swift, we provide the steps to create a multi-node environment consisting of a proxy server and five storage nodes.
To set up the lab environment, you will install and use Oracle's VirtualBox and Vagrant. You can access details of how to set up your computer using VirtualBox and Vagrant by visiting http://bit.ly/OpenStackCoobookSandbox.
There are additional recipes to get you started with the lab environment, and these are available at http://www.openstackcookbook.com. Refer to this website for information on the installation of supporting software such as MariaDB/MySQL. More information can be found at http://bit.ly/OpenStackCookbookPreReqs.
To fully utilize the automated Ansible scripts in Chapter 11, Production OpenStack, it is assumed that the reader has access to six physical servers.
This book is aimed at system administrators and technical architects moving from a virtualized environment to cloud environments; who are familiar with cloud computing platforms. Knowledge of virtualization and managing Linux environments is expected. Prior knowledge or experience of OpenStack is not required, although beneficial.
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Controlling OpenStack Object Storage services is achieved using the tool called swift-init."
A block of code is set as follows:
account-server: bind_port = 6000 container-server: bind_port = 6001 object-server: bind_port = 6002
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
[swift-hash]
# Random unique string used on all nodes
swift_hash_path_prefix=a4rUmUIgJYXpKhbh
swift_hash_path_suffix=NESuuUEqc6OXwy6XAny command-line input or output is written as follows:
sudo swift-init all start sudo swift-init all stop sudo swift-init all restart
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "An important field is the Common Name field."
