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

RADOS Gateway standard setup, installation, and configuration


For a production environment, it's recommended that you configure the RGW on a physical, dedicated machine. However, if your object storage workload is not too much, you can consider using any of the monitor machines as an RGW node. The RGW is a separate service that externally connects to a Ceph cluster and provides object storage access to its clients. In a production environment, it's recommended that you run more than one instance of the RGW, masked by a Load Balancer, as shown in the following diagram:

Starting with the Firefly release of Ceph, a new RGW frontend had been introduced: Civetweb, which is a lightweight standalone web server. Civetweb has been embedded directly into the ceph-radosgw service, making the Ceph object storage service deployment quicker and easier.

In the following recipes, we will demonstrate the RGW configuration using Civetweb on a virtual machine that will interact with the same Ceph cluster that...
