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.

Catching up with New Horizons Computer Learning Centers of Southern California

Based in Southern California, with five offices in Los Angeles, Orange, San Diego and San Bernardino counties, New Horizons Computer Learning Centers of Southern California was recently named Red Hat Training’s Ready Partner of the Year at the annual Red Hat Training Partner Conference in Las Vegas, NV. As part of the world’s largest independent IT training company, New Horizons Computer Learning Centers of Southern California is a learning solutions provider for the industry’s top vendors, and has been a Red Hat Training Partner since 2010. We recently caught up with New Horizons Computer learning Centers of Southern California’s CEO, Kevin Landry, for his thoughts regarding the state of the training industry today and how it will change tomorrow.

Who are you training these days?
The market we’re in is a little bit unique. 70% of our business is considered B2B or enterprise business, companies like Disney, Southern California Edison, and Ingram Micro. Working with Red Hat over the past several years, we’ve continually seen this business double year after year. Developers in training is the largest growth area, but the greatest area of interest we’ve seen increase has been in the consumer market, where individuals fund their own training. I’d say 30% of the individuals that we train fall into this latter group, and are funding training on their own or have alternative government funding, such as VA benefits or unemployment benefits.

What are the most common reasons people are getting trained right now?
Skill shortage is the main reason that individuals are seeking training, and being that it’s more likely these days to see Linux or Red Hat in a job description, we’ve seen a lot of growth in consumers seeking Red Hat Certifications.

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”.
