Introduction to Linux administration

What is Linux administration? I didn't find any exact phrase for it. Linux administration always described as job that Linux system administrator does. If that so, then Linux administration means everything about Linux such as Linux installation, create and manage user accounts, permissions, ownerships, hardware, software and data management, Linux networking system, Linux system and network security, software installation, system upgrade, backup and so on. That's basically true. To do administration on Linux system, a user needs to know everything about Linux. However, we don't do Linux installation everyday. So I would say, Linux administration is an on going tasks to make Linux operating system works in proper order, safe and secure.

This tutorial is the introduction of basic Linux administration tutorials available in website.It supposes to give some exposure before user skip to the administration section where the real deal is. Let's take a brief description about all Linux administration tasks mention above. I am not going to exposed the Linux system administrator's job. That's the big scope. Rather, the system administration that average Linux users need to know and implement on their system.

You probably know about Linux installation process and procedure. In reality, we don't install Linux everyday as I already mentioned but we do upgrade the system occasionally. The Linux administration really starts after the system is up and running. And probably the first thing we do is creating a new user account. It's a good practice not to use root account in daily use. That's why we need to create a normal user account and use su(switch user) to gain root privilege when we need to do system administration task.

If you have several other users in the system, then, the administration task normally would be creating user account, change password, disabling and removing user account. Other administration task maybe you need to set groups, file and directory permissions.

In a network environment, such as home networking or small office network, basically you have to setup network printer, file sharing server and Internet access. These tasks involve many processes and system administrations you need to do frequently. For example, you need to setup and manage network, system monitoring and software updates. Perhaps make regular backup too.

The most important administration task every Linux user need to do, whether in a network environment or standalone is to monitor Linux system. Monitoring disk usage frequently and setting up disk quota is recommended.
