Configure Yum Server (Part-1)

Configuring Local Yum Server on RHEL 5

Overview:

Yum or yellow dot update manager is the front of RPMs. It is only design for packages dependencies. Yum can collect packages from more than one location. To download & install RPM packages, it use a repository file, a repository is a single collection point for all documents that relate to the program. Generically repository refers to a central place where data is stored and maintained. A repository can be a place where multiple databases or files are located for distribution over the network, or a local machine. Yum first read this file list then it can download & install the packages.

Why Yum?

Generally in every Linux platform, it is difficult to install the packages (Software), because in Linux a single package is related with other packages, so if you want to install any package or packages then you need to know the other related packages/dependent packages name, but it is tough to remember so you can install packages by using yum. By using yum you can solve to installing all the dependent packages, this way you can remove the dependencies problem. Yum could be use as Local server that means by configuring yum you can install packages on local machine or can be use remote machines on your network. You can also download and install packages from internet by using yum.

Pre-requisites of Yum Server:

§  Configure NIC card on every machine
§  Update /etc/hosts file on both Linux system or use DNS system for name resolution.
§  A DVD-ROM with RHEL5 DVD
