Why study Linux?
Greetings,
If you’re reading these In other words, it’s because you probably made several decisions.
First of all, you, You probably know something about the Free Software movement in Brazil, and its importance for the economy of your country. You’ve probably noticed that there is an availability of source code for projects such as GNU and Linux Kernel, through which you can adapt the operating system for the better meet your needs or the needs of your employer.
Second, you may be using Linux on your PC at home, or maybe you’re an administrator of a system like Solaris, AIX, HP/UX, or some other Unix-owned system, and then you started using Linux at work. Or, you feel ready to work for a company that works as a Linux system full time.
Thirdly, you may have looked in a newspaper and noticed that some job advertisements are already requiring the candidate to have “LPI Certification” “, and you want to know the reason for such a requirement. After all, you already know how to maintain a Linux system!
When I started in Information technology, thirty-five years ago, things were much, much more simple than they are today. A programmer just needed to know how to drill cards and how to write in the FORTRAN (or COBOL) language. There was no Internet or viruses, only poor graphical interfaces, and main memory was measured at kilobytes, no megabytes or gigabytes. Actually, it didn’t even exist Any official title for the position we have today of “administrator of systems”, since each system was executed by “operators” who were concerned with a specific machine, and not with the interactivity of several machines that work together.
Today, we have to worry about security, network traffic and route tables, subnets, and so on network issues. We have to control the migration of data and programs from a system for the other, and the interoperability of various networks and protocols. we we have to be able to plan for growth, in addition to solving problems. And the Based on those needs that originated the tasks and the title of “System Administrator.”
In recognition of the phenomenal growth of the GNU/Linux operating system, the Linux Professional Institute, a A non-profit organization based in Canada, stipulated a series of qualifications that a Linux system administrator must have. They also created tests with the purpose of verifying that these assignments are mastered by the administrator in question.
So, if the administrator master a pre-defined average of those requirements, so he probably has the necessary knowledge to administer GNU/Linux systems. Maintaining In the spirit of Free Software, the institute published the objectives of the tests in your site, so that different study methods can be developed.
This course is an example of a training method to help you achieve this level of knowledge. We also have super complete books, including a Linux certification book PIC 1.
Knowledge of systems of GNU/Linux alone does not develop a master system administration master, but For the manager who is hiring, having someone who passed the LPI test gives you The certainty that he is hiring an administrator with a performance additional and measured through certification.
Of course the contractor also you can check the candidate’s potential with their former employers or teachers. And why not also check the employee’s previous achievements as listed on your resume? But the fact that the candidate passed the LPI exams assures the employer that the candidate in question is certainly a GOOD GNU/Linux system administrator.
For those who wish study and develop a career in Systems Administration, please feel safe using the objectives listed for each of the LPI exams and Think of them as a good study guide with the information you should know. Dots they were developed for system administrators and by administrators of systems. So, even if you don’t intend to take the exams of LPI formally, know that this material will make you a better administrator of systems.
Finally, welcome to this book, because it is a relatively cheap guide to studying and achieve your goal of becoming a GNU/Linux system administrator certificate.
It will not be the end of your learning, but a GOOD start.
