The Internet is a veritable treasure trove of Linux educational resources, but here are a few that we’ve hand-picked as especially useful.
First, Google it. Linux is so widely deployed that most common administration issues have been encountered, resolved and written about by others.
While there are a myriad of books available on RHEL administration, one of the most comprehensive is Michael Jang’s “RHCSA/RHCE Red Hat Linux Certification Study Guide”. While targeted towards certification-seekers, this tome covers just about everything you’ll need to know about Linux administration in a single, inexpensive volume.
For those who learn better visually, Michael Jang has also put together a virtual CBT course covering RHEL administration topics. Each section is presented with both narrated slides and screencasts of demos. While it’s more expensive than the book, it’s also far less expensive than an instructor-led course.
Red Hat and other 3rd party vendors offer instructor-led training both on-site and via virtual labs. While comparatively expensive, you are offered opportunities to collaborate one-on-one with expert instructors and test out your newfound knowledge in a safe, lab environment.
