One of the administrator's first tasks will be to manage the machine's local resources. Some of these aspects were basically covered in the GNU/Linux course. In this course, we will cover these management tasks in more depth as well as some of the customisation and resource efficiency aspects.
We will start by analysing the process for starting up a GNU/Linux system, which will help us to understand the initial structure of the system and its relationship with the various services that it provides.
Example 5-1. Note
Local administration covers many varied tasks, which are possibly the ones that the administrator will most use during their daily routines.
We will now learn how to obtain a general overview of the current state of the system, using different procedures and commands that are available for evaluating the various parts of the system; this will allow us to make administrative decisions if we detect any faults or deficiencies in the performance or if we find that we are missing any of the resources.
One of the administrator's main tasks is managing the user accounts, as any configuration of the machine will be designed for the users; we will see how we can define new user accounts and control the levels to which they may access the resources.
With regard to the system's peripherals, such as disks and printers, there are different management possibilities available, either through different servers (for printing) or different filing systems that we can treat, as well as some techniques for optimising the disks' performance.
We will also examine the need to update the system and how best to keep it updated; likewise, we will examine how to install new applications and software and how to make these programs available to the users. At the same time, we will analyse the problems involved in executing predetermined timed tasks in the system.
In the last tutorial, we will learn how to evaluate the state of a machine, following the points that we have seen in this module, and we will carry out some of the basic administrative tasks we have described. In this module, we will discuss some of the commands and subsequently, in the tutorial, we will examine some of these in more detail, with regard to how they work and the options available.
