What Is YUM?

YUM (Yellowdog Updater Modified) server is used for package installation for the client or local system while we use rpm(RedHat Package Manager) some packages are dependent on other so entire packages are not installed so we use yum server. YUMserver removes dependencies of packages

HOW TO INSTALL YUM

First, we have to connect the CD-ROM or iso image to system or server

Step-1: mount /dev/sr0 <space>/mnt

where your DVD or iso image is saved in VMware it is saved in /dev/sr0 or /dev/cdrom and /mnt is used for mounting the folder you can take any folder.

Step-2: cd<space>/mnt

Go to your mounting folder or /mnt

Step-3: ls
