Overview of this book

This Learning Path takes you through the basics of Ceph all the way to gaining in-depth understanding of its advanced features. You’ll gather skills to plan, deploy, and manage your Ceph cluster. After an introduction to the Ceph architecture and its core projects, you’ll be able to set up a Ceph cluster and learn how to monitor its health, improve its performance, and troubleshoot any issues. By following the step-by-step approach of this Learning Path, you’ll learn how Ceph integrates with OpenStack, Glance, Manila, Swift, and Cinder. With knowledge of federated architecture and CephFS, you’ll use Calamari and VSM to monitor the Ceph environment. In the upcoming chapters, you’ll study the key areas of Ceph, including BlueStore, erasure coding, and cache tiering. More specifically, you’ll discover what they can do for your storage system. In the concluding chapters, you will develop applications that use Librados and distributed computations with shared object classes, and see how Ceph and its supporting infrastructure can be optimized. By the end of this Learning Path, you'll have the practical knowledge of operating Ceph in a production environment. This Learning Path includes content from the following Packt products: • Ceph Cookbook by Michael Hackett, Vikhyat Umrao and Karan Singh • Mastering Ceph by Nick Fisk • Learning Ceph, Second Edition by Anthony D'Atri, Vaibhav Bhembre and Karan Singh

Installing the Ceph RGW multi-site v2 environment 


You need to install two clusters, and on each cluster, you need to install a minimum of one RGW daemon for client I/O and for RGW replication.

How to do it...

In this recipe, we will use the ceph-node1, ceph-node2, and ceph-node3 VMs for the first cluster, and in this cluster, we will use the us-east-1 VM for the RGW node. In the second cluster, we will use the ceph-node4, ceph-node5, and ceph-node5 VMs for cluster nodes and the us-west-1 VM for the RGW node.

You should use Chapter 1, Ceph – Introduction and Beyond, for installing both clusters and Chapter 4, Working with Ceph Object Storage, for installing RGW nodes in both clusters:

  1. Bring up all eight VMs with the help of the vagrant up command: 
        $ vagrant up ceph-node1 ceph-node2 ceph-node3 ceph-node4 ceph-node5 
          ceph-node6 us-east-1 us-west-1
  1. Once all VMs come up, log in and update to CentOS release 7.4 and then reboot to CentOS 7.4:
        # vagrant ssh <vm-name>
