Production Ready OpenStack - Recipes for Successful Environments

By: Arthur Berezin

Overview of this book

OpenStack is the most popular open source cloud platform used by organizations building internal private clouds and by public cloud providers. OpenStack is designed in a fully distributed architecture to provide Infrastructure as a Service, allowing us to maintain a massively scalable cloud infrastructure. OpenStack is developed by a vibrant community of open source developers who come from the largest software companies in the world. The book provides a comprehensive and practical guide to the multiple uses cases and configurations that OpenStack supports. This book simplifies the learning process by guiding you through how to install OpenStack in a single controller configuration. The book goes deeper into deploying OpenStack in a highly available configuration. You'll then configure Keystone Identity Services using LDAP, Active Directory, or the MySQL identity provider and configure a caching layer and SSL. After that, you will configure storage back-end providers for Glance and Cinder, which will include Ceph, NFS, Swift, and local storage. Then you will configure the Neutron networking service with provider network VLANs, and tenant network VXLAN and GRE. Also, you will configure Nova's Hypervisor with KVM, and QEMU emulation, and you will configure Nova's scheduler filters and weights. Finally, you will configure Horizon to use Apache HTTPD and SSL, and you will customize the dashboard's appearance.

Configuring Cinder with the Ceph RADOS block device backend driver

Ceph is an open source, software-defined storage system that runs on commodity x86 hardware. Ceph provides block storage volumes that can be attached as virtual disks. Ceph utilizes multiple hosts' local disks to create a unified virtual disk pool. Ceph can scale massively to petabyte storage pools and takes care of disk replication, rebalancing, and other storage maintenance operations.

Cinder implements an rbd (RADOS block devices) backend storage driver that can utilize the existing Ceph storage pool, manage volumes, and attach volumes to VM instances.

Getting ready

Before getting started with configuring a Ceph rbd backend driver, make sure to install Ceph client packages and the Python rbd binding library on all OpenStack nodes, including controller and compute nodes:

[root@controller ~]# yum install -y python-rbd ceph
[root@compute1 ~]# yum install -y python-rbd ceph

We will need to prepare a storage pool named cinder...
