Software Package Management

To keep your system up to date and install or remove applications as you choose, Linux supports multiple methods. One method is to use the source code of the application for compilation and installation on your machine. Another one is using pre-built programs or groups of programs known as packages, which are ready for installation on a particular distribution.

In this chapter, you will learn how to manage these pre-built software packages using RPM and the YUM utility. You will also learn how to add or remove official and third-party repositories in CentOS 7.

In this chapter, we will cover the following topics:

  • Managing applications using RPM
  • Managing applications using YUM
  • Managing official and third-party repositories
  • Creating custom repositories
