RHCE Training-Understanding YUM

In the early days, you needed to compile your GNU/Linux system manually from source, which used to
be very time consuming and could be problematic if you were not able to get all your dependend packages. In RHCE Training understanding YUM is very important. Not in RHCE, but in real life also. A clear understanding of working of YUM server is very helpful, sometimes.

Red Hat created Red Hat Package Manager (RPM) in 1998 to address the concerns of dependencies and reduce the time needed to install a system (among others). Since then, RPM has been improved by the Open Source community. One such improvement is yum. Yellowdog Updater, Modified (yum) is a package management tool using RPM. It allows RPM to access remote repositories and multiple repositories of RPM files and will automatically download the required RPM files based on the dependency information provided by RPM.

In your RHCE training days, you might have worked with YUM server and YUM client, in detail. No doubt, about that.

But I intend to share something which you might not have done in your RHCE training.
