In the context of the current cluster configuration; the compute nodes are isolated from the outside world and with no Internet access. When it comes to install new packages or to upgrade the old ones, the configuration of local software repositories become necessary. A software repository is a central file storage location to keep and maintain software packages from which the compute nodes can retrieve packages to install them. In this exercise you will learn how to setup a local YUM repository over Apache HTTP web server on CentOS 7 and how to find and install software packages on compute nodes.

Please note that the Apache web server was already configured in Exercise 2: Setting up a minimal netboot environment. No additional configuration of the web server is required.
