What is the difference between YUM and RPM?
YUM (Yellowdog Updater, Modified) and RPM (Red Hat Package Manager) are both package management tools commonly used in Linux distributions. While they are closely related, there are significant differences between them.
RPM is the lower-level package management system that handles the actual installation, updating, and removal of software packages. It manages individual package files and performs operations based on instructions provided by the package metadata. RPM primarily focuses on managing packages at a local level and does not handle complex dependency resolution.
On the other hand, YUM is a higher-level package management tool that utilizes RPM as its underlying engine. YUM acts as a front-end to RPM, providing a more user-friendly interface and advanced features. It simplifies package management by automatically resolving dependencies during installations or updates. YUM maintains a repository of packages, allowing users to easily search for and install software from a centralized source.
Here are some key differences between YUM and RPM:
- Dependency Resolution: RPM does not have built-in dependency resolution capabilities. Users need to manually handle dependencies when installing or updating packages using RPM. In contrast, YUM automatically resolves dependencies by fetching required packages from repositories.
- Repository Management: While RPM can directly install packages from local files, YUM focuses on managing repositories of packages hosted on remote servers. YUM allows users to add or remove repositories easily and provides commands to search, install, update, or remove packages from these repositories.
- System Updates: YUM excels in managing system-wide updates by handling groups of packages collectively known as “update sets.” It ensures that all installed software remains up to date with the latest versions available in the configured repositories. RPM primarily focuses on individual package operations rather than system-wide updates.
- User Interface: RPM operates through command-line tools with specific options for various operations such as installation or removal of packages. While it provides detailed control over package management tasks, it requires users to manually handle dependencies and other complexities. YUM, on the other hand, offers a more user-friendly command-line interface and can also be used with graphical front-ends like DNF (Dandified YUM).
In summary, RPM is the core package management tool that directly handles package operations, while YUM is a higher-level tool that utilizes RPM to provide advanced features such as dependency resolution, repository management, and system-wide updates. YUM simplifies the package management process and enhances the user experience by automating complex tasks that would otherwise need to be manually performed using RPM.
