Dnf was firstly introduced in Fedora 18, and does replace yum in the last version of Red Hat Enterprise Linux. To manage the relationships between packages, and avoid the infamous dependency hell, first yum package manager (Yellow Updater Modified) and then its evolution, dnf (Dandified YUM), were adopted. Although very powerful, it is focused on single packages, so it is not able to resolve dependencies. To ease the management of rpm packages, the rpm package manager was created. RPM: The Red Hat Package Manager and yum/dnf RHEL and CentOS uses the rpm package format which was invented by Red Hat itself: in this tutorial we will see how to install and manage rpm packages on Red Hat Enterprise Linux 8.

But what exactly is a package? A package is basically a compressed archive which contains the files associated with a specific software, like compiled binaries and libraries, plus metadata and instructions about where and how those files should be installed on the system, the external dependencies the software needs to run correctly and more. In RHEL 8 / CentOS 8, like in all modern linux distributions, software is organized in repositories, in the form of packages. $ – requires given linux commands to be executed as a regular non-privileged user # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command Permission to run command with root privileges. The utilities used in this tutorial are installed by default, there is no need for additional software.
