Evolution of Red Hat Courses and Exams with Red Hat Enterprise Linux 7

Red Hat Enterprise Linux 7 represents an exciting next step in the continued evolution of the product family and is perhaps the most comprehensive update in the 11 years I’ve been with the company. New tools such as systemd, firewalld, OpenLMI and others changes the paradigm for enterprise Linux administration by providing greater centralization and automation for the administrator. Other enhancements improve performance, security and scalability. Red Hat Training has substantially updated the RHCE level curriculum to integrate these improvements. The technical changes in the new release are such that even veteran, practicing Linux administrators should consider taking additional training.

In addition to incorporating new technical features from Red Hat Enterprise Linux 7, major releases provide an opportunity for Red Hat Training to make structural changes to improve our curriculum. Over the past two years we’ve surveyed our customers, partners and instructors and have been looking forward to the opportunity to make these changes. There are four enhancements I’d like to call out specifically.

1) Red Hat System Administration I (RH124) is the entry point to the Linux curriculum and is the first 5 days of the nine day curriculum leading to RHCSA certification. Based on customer feedback, we have substantially increased the command line administration approaches in the new course, diving right in on day one. In turn we will be retiring the Red Hat Command Line Administration (RH190) course.

2) Following feedback from our certified professionals community, the Red Hat System Administration III course (RH255) has been revised to include several chapters on shell scripting. The course continues to cover key network services such as Apache, DNS, iSCSI and also provides a tech preview of the new container features in Docker.

3) Perhaps the change I’m most excited about is the new Red Hat Certification Lab course (RH300) which replaces the flagship RHCE Rapid Track Course which first ran 15 years ago. The reality is that as Linux has become a true enterprise platform, the requirements to be a Red Hat Certified Engineer have grown commensurately. Red Hat’s courses are dense and its simply not possible to cover the thirteen days of content in Red Hat System Administration I, II and III in four days.

The new Red Hat Certification Lab course seeks to meet the very specific needs of students who have completed their training and desire practice before taking the RHCE exam. Students will spend 80-90% of their time “in labs”, complimented by a handful of lectures by an instructor on key new functionality like systemd, firewalld and the new boot process. Labs will be self-paced, with the instructor serving more as a teaching assistant as students require assistance. Students will have access to the full set of labs for both the RHCSA Rapid Track course (RH200) and the Red Hat System Administration III (RH255), providing comprehensive coverage for the competencies which are presented in the RHCSA and RHCE exams.

4) Over the past four years live virtual training (VT) and self-paced training have become primary delivery methods for our customers. To address those needs, the updated course materials and labs were redesigned to be completely inter-operable between different modalities, ensuring our customers get the same learning experience. Our self-paced training platform, Red Hat Online Learning (ROLE), is ready to deliver the System Administation I & II courses and the RHCSA Rapid Track globally via six Amazon EC2 data centers. The System Administration III course and the RHCE Certification Lab will be available in coming weeks as will translations of all five courses into eight other languages.

Tips For Restoring Permissions and ownership of Files in Redhat 6/7

Problem:
=======
Permissions and Ownership on critical system files (in /etc/) directory modified. This may cause the system to not boot, lots of errors and Kernel Panic.
cause:
=====
Someone accidentally typed chmod -R 777 /etc
Solution:
=========
The RPM package manager maintains a database for all files that it installs onto the system. This includes information such as the filename, installation path, owning package and the file system ownership and permissions (including SELinux file context information). In the event that ownership or permissions are inadvertently changed, for example, through accidental misuse of the chown or chmod commands, it is possible to revert these to their values as stored in the database.
1. To re-set ownership and permissions for all packages on the system:
root@ubuntu12:~# rpm –setperms -a
root@ubuntu12:~# rpm –setugids -a
2. To re-set ownership and permissions for a specific package on the system
root@ubuntu12:~# rpm –setperms <package name>
root@ubuntu12:~# rpm –setugids <package name>
……………….OR …………..
1) To reset uids and gids on files and directories :
root@ubuntu~:# for u in $(rpm -qa); do rpm –setugids $u; done
2) To permissions on files and directories
root@ubuntu12:~# for p in $(rpm -qa); do rpm –setperms $p; done

How To Get A Red Hat Linux Certification

Why Should I Get A Linux Certification?

Well, the first question you might have is why should you get a Linux certification? The answer to this is similar to getting certifications in general. It helps to prove your knowledge in the Linux operating system, by testing and passing a minimum standard of knowledge

.

It can also help you get a job in the industry. Many jobs require or prefer a certification in Linux, such as Linux administrators or general server administrators. It can also add to your existing Linux knowledge, which you could apply to your current job.

Which Linux Certification Should I Get?

This could be an entire post on its own - but I'll include all the information here in one convenient place.

There are four main providers of Linux certifications, and they all offer a range of different certifications for different levels.

Novell

They offer a range of certifications, with labels of Engineer, Professional and Desktop Administrator.

• Certified Linux Engineer 11 (CLE11) - provides engineer-level skills for managers and architects on large systems based on SUSE Linux Enterprise Server 11. You need to have passed the Certified Linux Professional 11 exam to be eligible for this.


• Certified Linux Administrator 11 (CLA 11) - a new certification, focusing on daily operation of SUSE Linux Enterprise Server networks.


• Certified Linux Desktop Administrator (CLDA) - focused on those with Windows desktop experience and wish to learn about SUSE Linux Enterprise Desktop.


• Certified Linux Professional 11 (CLP 11) - provides skills necessary to administrate SUSE Linux Enterprise Server.

CompTIA

ComptTIA only provide a single Linux certification, the Linux+.

• Linux+ - an entry-level certification for those looking to get into the Linux field. Vendor neutral.

Linux Professional Institute

The Linux Professional Institute, otherwise known as LPI, offer a few Linux certifications.

• Linux Professional Institute Certification Level 1 (LPIC-1) - a junior level Linux certification that tests basic skills in major Linux distributions.


• Linux Professional Institute Certification Level 2 (LPIC-2) - an advanced level Linux certification that includes skills in administration. Passing the LPIC-1 is required for this.


• Linux Professional Institute Certification Level 3 (LPIC-3) - a senior-level Linux certification for major Linux distributions that offers several specialties. Passing the LPIC-2 is required for this.

Red Hat

Red Hat offer a few certifications for their distribution of Linux.

• Red Hat Certified System Administrator (RHCSA) - a lower-level Linux certification that covers the basics of administration.


• Red Hat Certified Engineer (RHCE) - more advanced Linux certification, aimed at experienced Linux professionals. Passing the RHCSA is a requirement for this certification.


• Red Hat Certified Virtualization Administrator (RHCVA) - focused on deploying virtual hosts in the Linux environment


• Red Hat Certified Security Specialist (RHCSS) - focused on security features and areas of Linux


• Red Hat Certified Datacentre Specialist (RHCDS) - focused on the requirements for administrating and supporting datacentre environments


• Red Hat Certified Architect (RHCA) - the highest level of Red Hat certification, this focuses on expert topics of Linux administration and usage.

So, the answer to which Linux certification should you get?

It depends on your experience and requirements. There are several junior Linux certifications (Linux+, RHCSA, LPIC, CLE11) that could be useful if you're looking to start out.

More advanced certifications such as the RHCE, LPIC-2, CLA11 and CLP11 can be beneficial if you have more experience. If you're a senior professional in the Linux area, I'd look into the RHCA or the LPIC-3.

However, this article is focused on the Red Hat certifications, so we're going to look at how to get a Red Hat Linux certification in this article.

How To Get A Red Hat Linux Certification

The steps to getting a Red Hat Linux certification are fairly straight forward. I mean, the concept is simple, but actually doing the work and getting the certification can be tough, especially for the more advanced certifications.

The process you can follow is something like this:

• Determine which certification to get. This will come down to two things - which one you want, and which one you're eligible for. Have a look at the requirements and recommended experience for each of the certifications, and make a decision. Many of them are based on junior/intermediate/expert levels, and have prerequisite exams, which limits your choices. The Red Hat Certified System Administrator is a good place to start, if you're not sure.


• Determine the requirements. Confirm the requirements on the official website. This may include previous exams, years of experience, and certain knowledge. You should be eligible to sit the exam before attempting to study for it.


• Enroll in the course. Make an enrolment into the course, and set an exam date. Yes, do this before you even start studying. This will give you a deadline, and subconsciously motivate you to study more and get it done quicker. Without a set date, the study may just never happen.


• Study. Read the material, get familiar with the course work and the included topics. Take notes, practice, and learn.


• Sit the exam. Depending on the exam, it will be either a theory exam based on computers, or a live exam where you perform on a Linux machine.


• Pass. Knowing your material and getting the questions right will mean you pass the exam.


• Celebrate! Well done, you've passed the exam and earned a certification! All your hard work has paid off and now you're Red Hat Linux Certified!

Linux Certification Courses Benefits IT Professionals

Achieving Linux certification is important for IT professionals who want a way to prove to potential employers that they can manage, maintain, and troubleshoot the Linux operating system in an actual business environment. So Linux certification courses have been developed by vendors Red Hat Inc. and Novell, as well as SAIR, LPI and several other vendor-neutral several IT organizations to help candidates for certification prepare for their exams.

Becoming Linux certified at one or more levels benefits IT professionals by opening up employment opportunities, and hiring certified employees benefits employers by ensuring that their Linux operating systems and networks will function smoothly and securely. The Linux certification courses and exams offered by different vendors and institutions vary significantly, however, and many of them focus on theoretical knowledge at the expense of hands-on Linux OS and related software training.

Both the Red Hat and Novell certification courses expose their students to both textbook study of Linux and to lab sessions in which they experience simulated installation and management saturations like those they will have to face in the workplace. Thousands of businesses have migrated from Windows-based operating systems to Linux, which is much more economical, but the operating system, as an open source project, remains a work in progress.

Employers need to know that the IT professionals they hire to work on their Linux applications are prepared to handle their in-house needs as they arise. And Linux certification courses,and Redhat Certification Exam Center in Jaipur to be truly effective, will require students to show they are up to the task.

These courses build their students' theoretical understanding of the various aspects of the operating system, but that classroom learning is secondary to the laboratory work it gives students in the areas of Linux OS installation, software management, networking, troubleshooting, and security implementation. Linux certification candidates who pass the Red hat or Novell exams have shown that they are ready to take it on as it exists in the workplace.

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 6 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 6 is 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, Summer Training in Jaipur 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.
