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 Network File System (NFS) backend driver

Cinder can use network file system (NFS) shares as a storage backend driver using an NFS driver implementation. A Cinder-volume service takes care of mounting the NFS shares and creates volumes on the shares. The NFS driver works differently than other Cinder block storage drivers. The NFS driver does not allow an instance to access a storage block device, instead files are created on an NFS share and mapped to instances, which emulates a block device.

Getting ready

Cinder-volume utilizes the NFS client utilities. Make sure that the nfs-utils packages are installed on the hosts running cinder-volume and nova-compute:

[root@controller ~]# yum install nfs-utils nfs-utils-lib
[root@compute1 ~]# yum install nfs-utils nfs-utils-lib

Make sure that the NFS shares are exported with appropriate file permissions, so the cinder-volume service has read and write access.
