Understanding YUM (Yellowdog Updater, Modified)

YUM is a powerful tool for Red Hat Linux systems that simplifies software package management. It automates the process of resolving dependencies and downloading required packages from configured repositories.

Key Features of YUM:

• Automatic Dependency Resolution: YUM finds and installs all needed dependencies for a package, preventing software problems.

• Repository Management: YUM works with repositories, which are central stores of software packages, allowing easy installation and updates.

Command Examples:

• Install a Package: yum install [package-name]

• Update All Packages: yum update

• Search for a Package: yum search [keyword]

Understanding RPM (Red Hat Package Manager)

RPM is the underlying package management tool for Red Hat Linux, providing a strong way to manage individual software packages.

Key Features of RPM:

• Direct Package Management: With RPM, you can install, update, and remove packages directly without using a repository.

• Package Verification: RPM can verify the integrity and authenticity of packages installed on your system.

Command Examples:

• Install a Package: rpm -ivh [package-name].rpm

• Upgrade a Package: rpm -Uvh [package-name].rpm

• Remove a Package: rpm -e [package-name]

Learning Outcomes

By the end of this lab, you will be able to:

• Install & Update Software Packages: Gain skills to install new software & update current ones using YUM and RPM.
