You have been provided with a fairly basic installation of Scientific Linux. Apart from a few host-specific items (such as the host certificates), you will need to install the packages that dCache needs, along with the packages containing dCache itself.

The yum command is used to populate a computer with the additional packages necessary to run dCache. However, the yum command must be told from where it can receive these packages. This is achieved by creating files in the /etc/yum.repos.d directory. The following is a list of files to create, each informing yum where to find some necessary packages.
