This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.Red Hat Enterprise Linux 7 (RHEL 7) is the first major release of RHEL to allow in-place upgrades from the previous RHEL major release (RHEL 6).An in-place upgrade offers a way of upgrading a system to a new major release of Red Hat Enterprise Linux by replacing the existing operating system.Such analysis includes checking for removed packages, packages replaced by partially incompatible packages, changes in libraries, users and groups and various services.
A report of this analysis can help the administrator with the in-place upgrade - by identifying potential troubles and by mitigating some of the incompatibilities.
With our Product Security Team's support of Red Hat Enterprise Linux, you can safely deploy apps across physical, virtual, and cloud environments.
It was the first Linux distribution to use the RPM Package Manager as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.
Red Hat Linux 9, the final release, hit its official end-of-life on April 30, 2004, although updates were published for it through 2006 by the Fedora Legacy project until that shut down in early 2007.
Red Hat Linux introduced a graphical installer called Anaconda developed by Ketan Bagal, intended to be easy to use for novices, and which has since been adopted by some other Linux distributions.
NOTE: You can (and should) run Preupgrade Assistant multiple times to address anything that could cause problems before running the actual upgrade.
