Explore the basics of Linux system maintenance. Learn about system and security logs, troubleshooting the boot process, automating reports with scripting, and more.
- [Scott] Once a computer is up and running, it's tempting to just leave it on a desk or leave it in the rack and let it go. But it's important to check in once in awhile and make sure things are going alright. You want to have a sense of whether the computer is able to keep up with its tasks, whether the hardware's running well, and whether there are unpatched security problems you should resolve. Basic system maintenance is a necessary skill set for professional system administrators and hobbyists alike. I'm Scott Simpson, and in this course I'll show you the basics of Linux system maintenance.
We'll start with a video that will help you explore any Linux system you connect to in order to get your bearings if it's unfamiliar. Then we'll move on to a chapter about observing a system without making any changes. These are things you could do on a production system without harming anything, just to get a sense of how a system is performing. After that, we'll take a look at maintenance tasks that involve changing the state of the system. These are things you'd want to schedule some downtime for and double check before you put a system back into production. And then we'll finish up with a quick look at configuring your systems to send their log files to a central server for easy access.
