This Linux training course, Using and Administering Linux – Zero to SysAdmin, consists of three volumes. Each of these three volumes is closely connected, and they build upon each other. For those new to Linux, it’s best to start here with Volume 1, where you’ll be guided through the creation of a virtual laboratory – a virtual network and a virtual machine – which will be used and modified by many of the experiments in all three volumes. More experienced Linux users can begin with later volumes and download the script that will set up the VM for the start of Volumes 2 and 3. Instructions provided with the script will provide specifications for configuration of the virtual network and the virtual machine. Refer to the following Volume overviews to select the volume of this course most appropriate for your current skill level. This Linux training course differs from others because it is a complete self-study course. Newcomers should start at the beginning of Volume 1 and read the text, perform all of the experiments, and complete all of the chapter exercises through to the end of Volume 3. If you do this, even if you are starting from zero knowledge about Linux, you can learn the tasks necessary to becoming a Linux system administrator, a SysAdmin. Another difference this course has over others is that all of the experiments are performed on one or more virtual machines (VMs) in a virtual network. Using the free software, VirtualBox, you will create this virtual environment on any reasonably sized host, whether Linux or Windows. In this virtual environment, you are free to experiment on your own, make mistakes that could damage the Linux installation of a hardware host, and still be able to recover completely by restoring the Linux VM host from any one of multiple snapshots. This flexibility to take risks and yet recover easily makes it possible to learn more than would otherwise be possible.
