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

Accessing the Ceph object storage using S3 API


Amazon Web Services offer Simple Storage Service (S3) that provides storage through web interfaces such as REST. Ceph extends its compatibility with S3 through the RESTful API. S3 client applications can access Ceph object storage based on access and secret keys. S3 also requires a DNS server in place as it uses the virtual host bucket naming convention, that is, <object_name>.<RGW_Fqdn>.

How to do it…

Perform the following steps to configure DNS on the rgw-node1 node. If you have an existing DNS server, you can skip the DNS configuration and use your DNS server.

Configuring DNS

  1. Install bind packages on the ceph-rgw node:
        # yum install bind* -y
  1. Edit /etc/named.conf and add information for IP addresses, IP range, and zone, which are mentioned as follows. You can match the changes from the author's version of the named.conf file provided with this book:
        listen-on port 53 { 127.0.0.1;192.168.1.106; }; 
        ### Add DNS IP...
