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 RBD backup driver

Cinder supports a backup mechanism to back up Cinder volumes on external storage devices. Cinder has a Ceph rbd backup driver implementation allowing you to back up Cinder volumes to a dedicated backup Ceph pool.

Getting ready

Before getting started with configuring the Ceph rbd backup driver, make sure to install Ceph client packages and Python rbd binding library on node running cinder-backup service:

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

We will need to prepare a storage pool named cinder-backups:

[root@ceph-node1 ~]# ceph osd pool create cinder-backups 128

Also, we will need a copy of ceph.conf and Ceph keyring files with appropriate permissions on all controller nodes running the cinder-backup service:

[root@ceph-node1 ~]# ceph auth get-or-create client.cinder-backup mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=cinder-backups'
[root@ceph-node1 ~]# ceph auth get-or-create client.cinder-backup...
