Ceph Cookbook

Overview of this book

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe. This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you’ll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you’ll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We’ll also take a look at federated architecture and CephFS, and you’ll dive into Calamari and VSM for monitoring the Ceph environment. You’ll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you’ll get to grips with the best practices to operate Ceph in a production environment.

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...
