YUM Server

YUM (Yellow dog Updater Modifed) Server

The Yellowdog Updater, Modified (YUM) is an open-source command-line package-management utility for RPM-compatible Linuxoperating systems and has been released under the GNU General Public License. It was developed by Seth Vidal and a group of volunteer programmersYUM stands for Yellow dog Updater, Modified because it is based on YUP, the Yellow dog Updater. Yellow Dog is a version of Linux for the Power Architecture hardware. YUP, and later YUM, were written by the Linux community as a way to maintain an RPM-based system. If a package installation or upgrade request is made and requires the installation or upgrade of additional packages, YUM can list these dependencies and prompt the user to install or upgrade them.

YUM Server Requirements

1. vsftpd package to install rpm packages within a network.

2. Dump location to copy the contents from a RHEL CD or DVD  ie. /var/ftp/pub

3. deltarpm, python-deltarpm and createrepo packages

4. Repository file.
