Learning To Love Learning Linux

As 2015 comes to a close, I have come to realize a great truth: the best thing I ever did was to dump Windows and switch completely to Linux. I speak from my own experience but I also speak for many of my EzeeLinux clients who feel the same way. Of course, your mileage may very.  This article is not intended to sell you on Linux. Chances are good that if you’re reading this you already know about Linux and you may be using it every day. This article is for those who can’t seem to let go of Windows or Mac and are hanging on to those proprietary OS’s out of habit or because you’re not quite comfortable putting your entire computing life into the Linux space.

That being said, I can totally understand this because I was a Windows power user with some solid MS IT training under my belt. I knew the system and I was very confident in my ability to recover from a major Windows meltdown and get things going again, but I wasn’t so sure about Linux. I felt like I wasn’t quite ready to reformat my hard drives and go completely Linux because I was just a tad bit unsure of what I would do if something went wrong. Afraid to jump out of what I thought was my comfort zone, I made excuses every time I entertained the thought of making the break from Windows entirely. This state of mind stayed with me for years, so I kept my desktop machine loaded with Windows 7 and considered it my main PC while I ran Ubuntu on my laptop. I figured if the laptop died it would be no big deal, right? The funny thing was that the laptop ran damn near perfect for all of those years while I constantly chased Windows crashes, viruses and performance issues. The laptop just chugged along, doing its thing and hardly every complained. Still, I hung on to Windows, not quite ready to jump to Linux full time; not quite able to make the jump because I couldn’t get over all the what-ifs.


So, what was it that broke me out of this rut? It was a combination of things, really. First off, Ubuntu 14.04 came along and for the first time, I saw everything working right after I upgraded from 12.04, no tinkering required. The second thing that happened was that I bought a book about Linux Mint 16 called “Linux Mint Essentials” By Jay LaCroix. I eagerly awaited its arrival thinking I would gain tremendous insight into the inner workings of Linux Mint. While I did learn a lot of new stuff, I was kinda surprised at how much I already knew after finishing with it. The book really only whetted my appetite for more knowledge and so I decided that it was time to get serious about this Linux stuff and seek some training.

I didn’t have to look too far because I quickly came across The Linux Foundation’s “Introduction To Linux” course available through edX.  I’m not bragging, but I found the edX class to be somewhat like the book in that I found I knew a lot more than I thought I did. It seems that the previous ten years worth of reading about Linux, watching YouTube videos about Linux and fooling around with Linux myself had taught me a great deal. I felt my confidence rising more and more the further along I got in the course. And when it was done I knew for sure that I was ready to deal with just about any problem a Linux box might throw at me. The course is designed to be the first step toward becoming a certified Linux SysAdmin and there’s much in it that the average home user wouldn’t need on a daily basis but knowing a bit about networking, scripting and the command line certainly helps when you’re trying to figure out how to do something with your computer that goes beyond point and click. The main thing I took from the experience was the feeling that I had the knowledge required to make the system do my bidding and meet my computing needs. Microsoft’s days were numbered on my computer and I wouldn’t have to wait long before I had no choice but to take the leap.

The last straw turned out to be a dying hard drive. My Windows installation started freezing and a quick check of the disk’s stats revealed rising operating temperatures and a growing bad cluster count. I popped some new SSDs into my old Dell and loaded them with Linux and I haven’t looked back since.  All of the pitfalls I was so worried about have turned out to be non-issues. I have found software to do everything I need and in most cases it does a better job than what I was running on Windows. Reloading Linux is no big deal and I spent a few months doing some distro hopping, but now I have settled down into a groove that works great. The laptops run the latest and greatest Ubuntu and my desktops are happy with Linux Mint.
Notice that we have switched from singular to plural here. I now have a whole network of computers and I can honestly say that I wouldn’t have ever bothered with as many machines as I have now if they were running anything other than Linux. The main reasons I say this are because of the expense of buying a copy of Windows for each one and also because I would probably go crazy chasing down malware, viruses, updates and drivers for all of those Windows machines. One machine has five separate user accounts for family members and all I have to do is keep it updated when I log in with my admin account. Other than that, It just keeps on going.

Another thing that happened because of the jump to Linux was that I felt confident enough to convert my word-of-mouth freelance IT consulting side business into an outreach program to help other people get off of the Microsoft Money-go-round and get into Linux. All of that has led me here, writing this article for you and looking forward to what wonderful Linux-related things will come along in 2016.

One more thing I have found out is that I didn’t know Windows nearly as well as I thought I did. Looking back, I remember all of those times I stared at the screen asking myself, “What the &%$! is this thing doing?” It’s not like that with Linux. I usually can figure out what’s going on when my Linux machines have a hiccup or I at least know where to start looking. Never before in the 30 years that I’ve been working with computers have I ever felt so in control. Linux has made computing fun again and pretty much worry free.
If you’re sitting on the fence with Linux, take a look at the Linux Foundation “Introduction To Linux” course. You can audit it for free. What have you got to lose? Make it your New Year’s Resolution. Happy Holidays to you and yours where ever you are and whatever Holiday it is you celebrate. 2016 is going to be a wonderful year for Linux. I’m glad you’re here.

Why you want a bare metal hypervisor and how to choose

nce upon a time, there was nothing but native, or bare metal, hypervisors (a.k.a. virtual machine managers). In the 1980s, I cut my teeth on IBM System/370 mainframes running VM/CMS, but bare metal’s history goes all the way back to the 1960s. With bare metal hypervisors, the hypervisor runs directly on the hardware. There is no intervening operating system.
The formal definition of bare metal hypervisor, or, as it was called in its day, Type 1 hypervisor, goes back to Gerald Popek and Robert Goldberg’s seminal paper, Formal requirements for virtualizable third generation architectures. They also defined bare metal’s great competitor, the Type 2, or hosted hypervisor.
Today, bare metal virtual machines are still very much with us. VM/CMS evolved into IBM’s z/VM. And there are many other bare metal systems. Chances are you and your crew are using one even now.
Citrix’s open-source XenServer powers Amazon Web Services (AWS). Oracle VMfor SPARC and x86 are both based on Xen. There’s VMware’s ESX and ESXi,Microsoft Hyper-V, and HP’s Integrity VM.
While the implementations are quite different, the name of the game is to provide a minimal operating system that provides just what’s needed to run virtual machines. No more, no less. If you have an extra layer, like an operating system, between your VM and the hardware, that opens the door to performance, latency, security, scalability, and VM isolation problems.
There are corner cases of course. For example, you can still get a hot argument going in some circles if you suggest that KVM isn’t really a bare metal hypervisor.
For your servers, whether it’s just one Xeon box in the server closet, a thousand servers in your data center, or ten-thousand in your private cloud, what you really want is a bare metal hypervisor.

How to choose

For the mainstream operating systems there are four main choices: KVM, ESX/ESXi, Hyper-V, and Xen, in one form or another. You can argue until you’re blue in the face about which one is “better,” but generally speaking they all do an excellent job. More to the point of justifying the purchase to your CFO, each has its own role to play.

Install and Deploy JBoss Application Server

In this tutorial let's go over the process to setup JBoss application server to run web applications.
Install JDK 5.0
You can run the java -version command from your operating system's command line to check the version of your current JDK installation. If you are running a JDK earlier than 5.0, you need to upgrade. For Linux/Unix and Windows users, you can download the latest JDK from Sun'shttp://java.sun.com/j2se/1.5.0/download.jsp web site. For Mac OS X users, you should download the beta version of Apple JDK 5.0 from the http://www.apple.com/java/ site.
In order to run JBoss AS successfully, you also need to set the JAVA_HOME environment variable and point it to your JDK 5.0 installation directory. On a Windows system, you can do that via the XXX tool (i.e., XXX --> XXX --> XXX --> XXX). On a Unix / Linux / Mac OS X system, you can do it via shell scripts.
Install JBoss AS
To install JBoss AS, you first have to download it from thehttp://labs.jboss.com/portal/jbossas/download web site. Make sure that you download the installer file (e.g., the jboss-4.0.4-installer.jar file). Run the installer with the java -jar jboss-4.0.4-installer.jar command. You will go through a series of screens to consent the license terms, and select an installation directory (see Figure 1)
Select an installation directory
Figure 1. Select an installation directory
When the installer prompts you to select a server configuration, select either "ejb3" or "ejb3 with clustering" (see Figure 2).
Select the EJB3 modules to install
Figure 2. Select the EJB3 modules to install
You will be asked to choose a configuration name for this installation, leave it as default (see Figure 3). This way, you will be able to start the server without extra command line arguments.
Use "default" as the configuration name
Figure 3. Use "default" as the configuration name
The installer will also give you options to secure JMX remote invokers. Those invokers allow remote users to look into your running server and even do things with it. Do secure all those and give a username/password combo to protect those resources (see Figure 4.).
Secure all JMX invokers
Figure 4. Secure all JMX invokers
How about the Seam library?
Since an independent Seam container needs to be loaded for each Seam application (see ???), thejboss-seam.jar file should be included in the application EAR file.
Deploy and Run Applications
To deploy a web application, you only need to copy the .ear application file (i.e., the build target from the source code) into the JBoss AS's server/default/deploy directory. To start the server, run bin/run.sh (or bin\run.bat on Windows). You can now access the web application URL http://localhost:8080/myapp/. Of course, replace myapp with the application URL configured in your EAR (or WAR) file.
Ant
In order to build the example application from source code, you should also have Apache Ant installed. Please refer to the Ant documentation on how to install and use it.

JBoss Application Server 5 compatibility issues

The following are current compatibility issues for JBoss AS5:
  1. JBossAS 5 runs under Java 5 but there is an ongoing task to make it run safely under Java 6, too http://jira.jboss.org/jira/browse/JBAS-5031. If using a Sun Java 6 runtime, you may want to set -Dsun.lang.ClassLoader.allowArraySyntax=true, as described in http://jira.jboss.org/jira/browse/JBAS-4491.
  2. If using proprietary JBoss/EJB3 annotations, those have moved into the org.jboss.ejb3.annotation package, http://jira.jboss.org/jira/browse/EJBTHREE-1099. Those are now included in a new artifact, jboss-ejb3-ext-api.jar
  3. Work on EJB3 Extended Persistence Context support is not completed, http://jira.jboss.org/jira/browse/EJBTHREE-1026.
  4. Interoperating with previous JBoss EJB3 implementations may present problems due to serialVersionUIDs issues, http://jira.jboss.org/jira/browse/EJBTHREE-1118.
  5. EJB 2.1 View requirements
    • Home extending EJBLocalHome? or EJBHome must be defined
    • Remote or Local interface must either be defined via @Local/@Remote or via return type of “create<METHOD>” methods of the Home
    • EJB 2.1 Remote/Local interfaces must extend EJBObject/EJBLocalObject
  6. @Local/@Remote may be used to define either EJB 3.0 View Business Interface, or EJB 2.1 View Remote/Local interface
  7. Use of JBoss Cache 2.x. JBC 2.x has a significantly different API from the 1.x releases used in JBoss AS 4.x and 3.2.x.

RHCSA: A New Base Level Certification From Red Hat

The new version of Red Hat Enterprise Linux 7 is now released and with this new arrival, certifications under RHEL 7 will no longer be current. Red Hat Certified Technician (RHCT) exam is no longer offered by Red Hat. RHCT exam is now replaced by RHCSA (Red Hat Certified System Administrator). This article attempts to provide a clear picture about new changes in RHCE certification.

RHCSA is the new addition to the performance based certifications, to strengthen IT professionals with superior training and performance based assessments in the IT industry. The certification title itself indicates more precise description of the duties held by people with this certification. More over RHCSA is built with thorough analysis of the knowledge and skills needed for modern system administrators. This is an outcome of technical survey, task analysis and feed backs from professionals world wide. In effect RHCSA is similar to RHCT except with some additions to include the result of feed backs from professionals.

RHCSA is the base system administration certification. Now onwards those wishing to earn RHCE on RHEL 7 must get RHCSA and write separate exam for RHCE. RHCE is now upgraded as a higher level system administration certification. A current RHCE will remain as prerequisite for advanced level certifications from Red Hat.

The main changes with RHCE exam on RHEL 7is that previous RHCE Exam (RH302) will be replaced by RHCSA Exam (EX 200) and updated RHCE Exam (EX300). These two exams are now separate and RHCSA is not embedded with RHCE as RHCT was earlier. It is not necessary that one must get RHCSA first, before being eligible to write RHCE exam. If one passes RHCE exam first, then their record will be retained and when they passes RHCSA the earlier RHCE will be clubbed and person will be then RHCSA and RHCE. RHCSA exam is also performance based which evaluates skills through hands-on lab based system.

Certifications from Red Hat provide validation of a professional's technical expertise and knowledge. Nowadays enterprises looking for employees can give more preference to certifications as an input into hiring, promotions and other allowances, as these certifications are obtained from performance based exams.

Best Linux Certifications for 2015

If there's one major star in the vendor-specific Linux certification firmament, it's got to be Red Hat. Where Novell has history and deep knowledge of certification programs to its credit, Red Hat has major market presence and serious duration as a commercial provider of Linux platforms and technologies.
Like so many other certification programs, Red Hat offers a typical administrator -- engineer -- architect ladder; unlike many other such programs, however, it offers highly-regarded and -- valued credentials at each rung, along with demanding and hands-on oriented exams and an excellent training curriculum to match. All exams for the following Red Hat certifications are performance based, and last 2 hours or longer.
The giveaway for Red Hat certifications is that all come with acronyms that start with RH, as follows:
  • Red Hat Certified Systems Administrator (RHCSA): The foundation Red Hat certification, which vets essential skills in handling files, working at the command line, and using system documentation, along with managing systems (boot-up, identifying processes, start/stop virtual machines, controlling systems), configuring storage partitions and logical volumes, and more. $400
  • Red Hat Certified Engineer (RHCE): The cornerstone Red Hat certification, it is designed to test and validate the skills and knowledge necessary to work as a senior level Linux system administrator. Topics covered include advanced IP routing and services, managing runtime kernel behavior, working with iSCSI, automating maintenance tasks with shell scripts, and working with networking services for Web, FTP, NFS, SMB, SMTP, SSH and more. An RHSCA is a pre-requisite for the RHCE. $400
Because Red Hat Linux is widely used in the business world, it makes an excellent choice for those interested in a more platform-focused path into the Linux world. Of course, for those who already work with or around Red Hat, it is a natural certification choice as well.
Table 4: Red Hat Administrator, Engineer and Architect Credentials
Certification Name:Red Hat Certified Systems Adminsitrator (RHCSA)
Red Hat Certified Engineer (RHCE)
Red Hat Certified Architect (RHCA)
Prerequisites & Required Courses:After the RHCSA, each subsequent level takes the preceding level as a pre-requisite, courses are not mandated, but exams are often bundled with and taken immediately after their conclusion (as seniority climbs, more candidates take the classes).
Number of Exams:1 practical hands-on exam for RHCSA and RHCE; the RHCA requires 5 exams. See preceding certification links for exam ID details and sign-up.
Cost per Exam:RHCSA and RHCE exams cost $400; each of the RHCA exams costs $600 ($3,000 total).
URL:www.redhat.com/training/certifications/#certifications
Self-study Materials:Red Hat offers online and in-class training for its credentials, with excellent coverage for most of them on the aftermarket. Start with Amazon searches on RHCSA and RHCE to get a sense for what’s available. See also the Red Hat Training Resources links.
