What is Rocky Linux?

Rocky Linux is a community-driven, enterprise-grade Linux distribution designed to be a seamless replacement for CentOS Linux. It aims to provide a stable, reliable, and free alternative to CentOS, particularly for organizations and users who were relying on CentOS for their production environments and enterprise workloads.

Key features of Rocky Linux include:

  1. Stability and Reliability: Built on a solid foundation, Rocky Linux inherits the stability and reliability of its predecessor, CentOS Linux.
  2. Community-Driven Development: Rocky Linux is developed by the community, with contributions from volunteers, organizations, and developers around the world. This ensures transparency, accountability, and responsiveness to the needs of users.
  3. Binary Compatibility: Rocky Linux aims to maintain binary compatibility with Red Hat Enterprise Linux (RHEL), providing a compatible environment for applications and workloads developed for RHEL.
  4. Long-Term Support (LTS): Like CentOS Linux, Rocky Linux offers long-term support (LTS) with regular security updates and maintenance releases, providing stability and peace of mind for enterprise users.
  5. Free and Open Source: Rocky Linux is distributed under open-source licenses, allowing users to freely use, modify, and distribute the software, in alignment with the principles of the open-source community.

Rocky Linux was initiated by Gregory Kurtzer, one of the original co-founders of CentOS Linux, in response to the shift in CentOS’s focus from being a downstream rebuild of RHEL to CentOS Stream. It aims to fill the gap left by CentOS’s transition and provide a viable alternative for users seeking a stable, community-driven Linux distribution for their production environments and enterprise workloads. Thus Rocky Linux may be be considered as the best alternative for CentOS 8 by Linux enthusiasts.

What is Minimal Installation?

Minimal installation refers to installing an operating system with only the essential components required for basic functionality. It typically includes only the core components and essential system services necessary for the system to boot and perform basic operations.

In the context of Linux distributions like CentOS, Fedora, or Ubuntu, a minimal installation option is often provided during the installation process. Choosing this option installs the operating system with a minimal set of packages, resulting in a lightweight and streamlined system with minimal disk space and resource requirements.

Here are some characteristics of a minimal installation:

  1. Basic System Utilities: Minimal installations typically include essential system utilities such as a shell, package manager, and basic command-line tools necessary for system administration and management.
  2. No Graphical Interface: A minimal installation usually does not include a graphical desktop environment or any graphical applications. This helps reduce the disk space and memory footprint of the system.
  3. Limited Pre-installed Software: Minimal installations come with only a small set of pre-installed software packages, focusing on core system components rather than additional applications or utilities.
  4. Customizable: Users can add additional packages and software as needed after the minimal installation is complete, using the package manager to install only the software they require.
  5. Resource Efficient: Minimal installations consume fewer system resources (such as CPU, memory, and disk space) compared to full installations, making them suitable for resource-constrained environments or specialized use cases where performance is critical.

Overall, a minimal installation provides a lightweight and efficient base system that users can customize and expand according to their specific requirements, making it a popular choice for servers, virtual machines, containers, and other deployments where resource efficiency and flexibility are important.
