It is doubtful that a newly installed RHEL 9 system will contain all of the software packages to perform the tasks for which it is intended. Even once all the required software has been installed, it is almost certain that newer versions of many of those packages will be released during the system’s lifespan. In…

Red Hat Enterprise Linux 9 includes the GNOME 40 desktop environment. Although lacking the complexity of Windows and macOS desktops, GNOME 40 provides an uncluttered and intuitive desktop environment that provides all of the essential features of a windowing environment with the added advantage that it can be learned quickly.

In the previous chapter, we looked at installing Red Hat Enterprise Linux 9 on the same disk as Windows. This so-called “dual boot” configuration allows the user to have both operating systems installed on a single disk drive with the option to boot one or the other when the system is powered on. This chapter…

Like most Linux distributions, Red Hat Enterprise Linux 9 will happily co-exist on a hard disk drive with just about any version of Windows up to and including Windows 11. This is a concept known as dual-booting. When you power up the system, you will be presented with a menu providing the option to boot…

There are now two ways in which a RHEL 9 system can be deployed. One method is to either purchase new hardware or re-purpose an existing computer system on which to install and run the operating system. Another option is to create a cloud-based operating system instance using services such as Amazon AWS, Google Cloud,…
