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 logical volume management backend driver


Cinder's default backend storage provider is LVM. When cinder LVM backend driver is configured, a Cinder-volume service consumes a preconfigured volume group of the host Cinder-volume runs on. Cinder-volume manages the logical volumes of the configured volume group and uses an iSCSI target helper to provide a direct connection path to the volume.

Getting ready

In this recipe, we will configure LVM Cinder backend storage provider. A cinder-volume service will utilize a volume group of the host cinder-volume service runs on. Before getting started with configuring the Cinder backend driver, we need to make sure that the database, message broker, and Keystone are set for Cinder.

Additionally, make sure that the Nova-compute hosts are set to consume Cinder API.

[root@controller ~]# grep cinder.API /etc/nova/nova.conf
volume_api_class=nova.volume.cinder.API

To create an LVM volume group to be consumed by the cinder-volume service...
