Overview of this book

<p>OpenStack is an open source cloud operating stack that was born from Rackspace and NASA and became a global success, developed by scores of people around the globe and backed by some of the leading players in the cloud space today.<br /><br />OpenStack Cloud Computing Cookbook, Second Edition will show you exactly how to install the components that are required to make up a private cloud environment. You will learn how to set up an environment that you manage just as you would a public cloud provider like Rackspace with the help of experienced OpenStack administrators and architects.<br /><br />We begin by configuring the key components such as identity, image compute, and storage in a safe, virtual environment that we will then build on this throughout the book. The book will also teach you about provisioning and managing OpenStack in the datacenter using proven DevOps tools and techniques.<br /><br />From installing or creating a sandbox environment using Vagrant and VirtualBox to installing OpenStack in the datacenter, from understanding logging to automating OpenStack installations, whatever level of experience or interest you have with OpenStack there is a chapter for you. Installation steps cover compute, object storage, identity, block storage volumes, image, horizon, software defined networking and DevOps tools for automating your infrastructure OpenStack Cloud Computing Cookbook, Second edition gives you clear step-by-step instructions to installing and running your own private cloud.</p>

Stopping and starting Nova services


Now that we have configured our OpenStack Compute installation, it's time to start our services so that they're running on both of our OpenStack Compute virtual machines (Controller and Compute), ready for us to launch our own private Cloud instances.

Getting ready

If you haven't done so already, ssh to our OpenStack Controller and OpenStack Compute virtual machines. If you created these using Vagrant, you can log in to these using the following commands in separate shells:

vagrant ssh controller
vagrant ssh compute

This ensures that we can access our virtual machines, as we will need access to spin up instances from your personal computer.

The OpenStack services that we have running as part of our sandbox environments are as follows:

Controller:

  • nova-api

  • nova-objectstore

  • nova-scheduler

  • nova-conductor

Compute:

  • nova-compute

  • nova-network

  • libvirt-bin

How to do it...

Carry out the following steps to stop the OpenStack Compute services we have running:
