How to use a Red Hat Storage volume as Red Hat Enterprise Linux OpenStack Platform Cinder block storage back end

by Rudi Kastl, curriculum manager, Red Hat

By default, the packstack installer uses either a volume group named cinder-volumes or a loopback device as back end for the Cinder block storage service. For professional purposes, this is not enough; the usual requirement is to have a redundant storage back end. If you have an existing Red Hat Storage service, you might want to use one of the GlusterFS volumes as back end for the block devices your virtual machines use in the Red Hat Enterprise Linux OpenStack Platform cloud.

Before starting the configuration, you must remove all existing Cinder volumes, or you will run into problems. To figure out if there are any existing volumes with your current Cinder setup issue:

source /root/keystonerc_admin
cinder list

If there are any volumes listed, delete them with:

cinder delete volumename

Now that you have a cleaned-up Cinder setup, you can configure the back end to exclusively use the Red Hat Storage GlusterFS volume(s).

Start off by installing the GlusterFS-fuse package on the Cinder host, available in the Red Hat Storage Native Client repository from Red Hat Network.

yum -y install GlusterFS-fuse

Installing OpenStack with PackStack

by Forrest Taylor (Red Hat)

To install Red Hat Enterprise Linux OpenStack Platform manually can be an odious task, but packstack can assist in making the installation much easier and consistent. Normally, packstack is run from the controller node, which can either be a physical machine or a virtual machine.

Start by installing the machine with the latest Red Hat Enterprise Linux. Subscribe to the Red Hat OpenStack channel, as well as any other channels desired.

Next, install the openstack-packstack package using yum:
~]$ sudo yum install openstack-packstack

As root, use packstack to generate an answer file:
~]# packstack –gen-answer-file ~/answers.txt

Red Hat Training recognizes its top partners, resellers and instructors in Europe, Middle East and Africa

by Jessica Benton (Red Hat)

During this year’s Red Hat Partner Conference EMEA in Madrid, Spain, Red Hat Training gave an update on its new training and certification roadmap. The event covered new delivery methods and courses, including a three day exam marathon during which a total of 70 partner employees had a chance to take a free-of-charge certification exam. In addition, a training partner round table was held to discuss new opportunities for Red Hat Training and our partners. As is tradition, we also held an awards ceremony, recognizing those that have made the biggest impact over the course of the last year in training and certifications.

It is with great pleasure that I reveal the awards given that night:

Training Partner of the Year
Eastern Europe

Datascript, Czech Republic
Datascript is one of our oldest training partners in Eastern Europe and offers our complete training portfolio, from RHCE and RHCA up to the advanced middleware courses in the countries of Czech Republic and Slovakia. For the third year in a row DataScript has earned this prize.

Red Hat Training recognizes its top North America instructors

by Ralph Rodriguez (Red Hat)

During Labor Day Week, Red Hat Training North America held its annual Instructor and Partner Conference in Las Vegas, Nevada. As is our tradition, on the final evening, we held our awards banquet, recognizing the instructors that have made the biggest impact over the course of the last year.

It is with pleasure that I reveal the instructor awards given that night:

Special Award for Training Advocacy
Rhett Williams

Rhett teaches in Southern California, a significant growth region for Red Hat Training. That growth is a result, in part, of his advocacy of Red Hat Training among his students. Without being a “salesman”, he talks to students about Red Hat’s training programs, training tracks, and other courses that will help them, resulting in an extremely satisfied, customer base.

Behind Red Hat Server Hardening (RH413)

by Scott McBrien (Red Hat)

My name is Scott McBrien. I work for the Red Hat Training Curriculum Development Team and was the project leader for the development of the Red Hat Server Hardening (RH413) course. Before joining the Red Hat Training Curriculum Development Team, I worked as both a Red Hat training instructor and consultant. I hope that my field experiences show through in our new class.

When I first started thinking of writing a security focused class, I tried to think about what story would make a compelling course that I, and other systems administrators, would like to attend. One of the topics that I have seen grow to be pervasive in the systems administration community is Security Policy Compliance. Many of us have had the lovely experience of having someone from another team, or an outside consultant, come in to run some type of scanning software against our machine, and say “You’re not in compliance with SECURITY-STANDARD”. In my experience, the systems administrator is told to fix the deficiency without a lot of direction from the person telling them that there’s a problem, or worse, they are given instructions by someone who is not an expert on the technology, which fixes the audit deficiency, but down the line causes problems. A situation that I see over and over again is systems administrators being told to install non-supported software on their Red Hat Enterprise Linux machines because the version they have is “old” or “vulnerable”. In reality, Red Hat does a lot of work to publish updates to Red Hat Enterprise Linux (and other products) so that an administrator can use supported, packaged software from Red Hat and not have software open to known vulnerabilities. Red Hat’s update management and application of updates is the first topic in “Red Hat Server Hardening”.

Red Hat announces new OpenStack certification

by Iain Gray, vice president, global services, Red Hat

Today is an exciting day for Red Hat as we announce our new Red Hat Certificate of Expertise in Infrastructure-as-a-Service and expanded training in support of Red Hat’s OpenStack technology.

We launched Red Hat Enterprise Linux OpenStack Platform at the Red Hat Summit in June as a core part of our open hybrid cloud strategy. There is a huge amount of excitement about OpenStack both at Red Hat and from our customers. In terms of company focus, it truly is “the next Linux.” Our goal is to bring our enterprise experience to the Infrastructure-as-a-Service (IaaS) market and provide an OpenStack platform that our customers can trust.

We are committed to providing services that help our customers use OpenStack to get their products to market faster. We recently launched a range of IaaS-focused offerings. From cloud migration strategy consulting, to Red Hat Enterprise Linux OpenStack Platform product-pilot implementation services, through complete IaaS-based solution development, we can support our customers through every stage in their cloud journey. Red Hat OpenStack Administration (CL210), a course we introduced earlier this year, helps customers build their teams’ readiness to adopt and use this new technology.

Today, we complement and expand these offerings by introducing the Red Hat Certificate of Expertise in Infrastructure-as-a-Service and expanding the Red Hat OpenStack Administration course to cover new capabilities in the latest release and to provide preparation for the Red Hat Certificate of Expertise in Infrastructure-as-a-Service Exam (EX210).
