How do you install a service using the yum package manager?

To install a service using the yum package manager, the command yum install package_name is employed. This command specifically facilitates the installation of a specified software package from the repositories configured on the system. When this command is executed, yum resolves dependencies, downloads the necessary files, and installs the specified package along with any additional required packages, allowing users to deploy applications and services seamlessly.

Using yum install is a fundamental step in managing software on RPM-based systems like CentOS, Fedora, and Red Hat Enterprise Linux. The command not only ensures that the requested software is installed but also manages the installation of any dependencies that the software requires to operate correctly.

In contrast, while apt-get install package_name pertains to Debian-based systems, and yum upgrade package_name is focused on upgrading rather than installing new software, the command dnf install package_name is a more modern replacement for yum in some distributions, but is still considered distinct from the legacy process. Thus, while dnf may also install packages, the context of using yum is specifically captured by the correct choice.
