说明
yum (Yellowdog Updater Modified) is the traditional package manager for Red Hat-based Linux distributions. On modern systems (RHEL 8+, Fedora 22+), yum is a symlink to dnf, which provides the same functionality with improved performance. On older systems like CentOS 7, yum is the native package manager handling package installation, updates, and removal from configured repositories.
