This course was designed to share my experience as a Linux system administrator through practical examples and scenarios. If you would like to start a career in Linux or simply improve your knowledge, this course is for you. Throughout the course, I will show you many of the tasks you would encounter when administering a Linux server.
Since being a system administrator, I know you might need to deal with more than only one Linux distribution, what I teach in this course, applies to many of them.
I know that the best way to learn something is by actually doing it, so I created this course by showing how to accomplish the tasks rather than just explaining how to do them in theory. Moreover, along with the video lectures, you will also find exercises to help you improve your hands-on experience. You will benefit for free from any new lectures and updates on the course.
Keep in mind that if you are not happy with the course, you can ask for a refund and take advantage of 30-Day Money-Back Guarantee.
This is an introduction lecture to show you the content of the rest of the section.
This lecture explains the role of the runleveles and targets as well as what they are.
This is a practical example of how to identify the current runlevel and also the default one a Linux servers boots into.
This video shows how you can change the default runlevel when using an Ubuntu server.
In this video, you will learn how to list the services that are active in a specific runlevel.
This lecture shows how you can make a program start automatically at boot time as well as disabling them from starting by itself when Linux server boots. This helps you control the boot process.
Newer distributions has replaced the runlevels with targets. However, they have the same role and purpose.
This video shows you how to start/stop processes using systemd instead of init. Attached to this lecture, there is also an exercise to practice what you have already seen in this section
This video explains what LVM is when dealing with disk space.
In this lecture, you will get to know the steps necessary to create a volume group.
These are the steps to extend an existing volume group when you want to add more disk space.
Extend the filesystem and the logical volume with the unallocated disk space from the volume group, after removing the physical volume.
In this lecture, you will understand what NFS is and how it is used to share the files across the network.
In this lecture, you will learn how to implement NFS in order to share files with other Linux servers
In this lecture, you will learn to permanently mount the NFS shared directories, on the client server
This quiz gathers part of the knowledge you should remain with after finishing the course. The questions are similar to the Linux exam certifications.
I am a Linux System Administrator with more than 4 years experience, also M.Sc.Eng. in Computer Science.
I also have several certifications for the field I work in such as:
- LPIC-1: System Administrator
- LPIC-2: Linux Engineer
- ITILv3 Foundation Level
I am glad to be part of Udemy Community and also very eager to share my passion and knowledge about Linux with you.
