Ever wanted to instantly have Drupal, Moodle, OTRS, MySQL, WordPress, Zimbra, Bugzilla, phpBB or a slew of other open source software packages up an running in a hassle-free manner to try out or available for rapid deployment? TurnKey Linux gives you just that.
They provide live CDs that can be installed to disk along with virtual appliances for a wide array of needs. The appliances run in Amazon's cloud or on VMware, VirtualBox, Parallels, and Xen. They describe themselves as:
Turnkey Linux is an open source project developing a free virtual appliance library that features the very best server-oriented open source software. Each virtual appliance is optimized for ease of use and can be deployed in just a few minutes on bare metal, a virtual machine and in the cloud.
Why? Because everything that can be easy, should be easy.
Packaging a solution as a virtual appliance can be incredibly useful because it allows you to leverage guru integration skills to build ready to use systems (I.e., turn key solutions) that just work out of the box with little to no setup.
TurnKey's appliances really are a dream to use. It just doesn't get much easier. As an example, I am going to walk you through getting the WordPress Appliance up and running.
To start this off, I downloaded the WordPress appliance from their site in virtual machine format. I then fired it up in VMware Workstation and saw a nice little surprise... on first boot it downloads and installs all the security updates since the creation of the appliance. Once that was finished I was greeted with a screen that is standard for TurnKey:
Between the info given here and the options located in the advanced menu you should be able to perform most any task.
At this point, you can walk away from the appliance's terminal as everything can be managed via your web browser from here on out... even terminal-based things like manually running updates. This is possible thanks to their "Web Shell" which is actually Shell In A Box.
**As you may have noticed, I logged in as root... be sure to set a password as it is blank out of the box.
Now, the important part is the WordPress site itself. For this just navigate your browser to either the http or the https address listed next to Web: in the console and you will be presented with this:
From here you can dive right in just as you would on any other WordPress site... the difference is that all the real work to get this up and running has been done for you. To put it in perspective, with the exception of the download time for the 178MB ZIP, it took me longer to write this than it did to get the site up and running!
If you decide to give one of the TurnKey appliances a test drive then be sure to read the notes on their respective pages. All the info about credentials is there along with other useful information.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
