Is Centos 7 The Same As Rhel 7

Linux

CentOS 7 and RHEL 7 are two popular operating systems in the Linux world. As a technical enthusiast who has extensively used both, I am often asked about the similarities and differences between these two operating systems. In this article, I aim to provide a comprehensive comparison between CentOS 7 and RHEL 7, from a personal perspective.

Introduction

CentOS 7 and RHEL 7 share a common foundation, as RHEL is the upstream source for CentOS. Both operating systems are based on the Red Hat Enterprise Linux (RHEL) operating system, which is known for its stability, security, and enterprise-level support. CentOS aims to provide a free and open-source alternative to RHEL, offering the same functionality and compatibility.

Similarities

CentOS 7 and RHEL 7 have several similarities:

  1. Package Management: Both operating systems use the YUM package manager for installation, removal, and updating of software packages.
  2. Kernel: CentOS 7 and RHEL 7 use the same kernel, which provides the core functionality of the operating system.
  3. Filesystem Hierarchy: The directory structure and organization of files are identical between CentOS 7 and RHEL 7.
  4. Command Line Interface: The command line interface (CLI) and associated utilities are the same in both operating systems, allowing administrators to perform various tasks efficiently.

Differences

While CentOS 7 and RHEL 7 share many similarities, there are some notable differences:

  1. Support: RHEL provides official support from Red Hat, including access to security patches, bug fixes, and technical assistance. CentOS, on the other hand, relies on community support without the formal backing of a company.
  2. Updates: RHEL offers regular updates through its subscription model, providing new features and improvements. CentOS mostly follows the updates of RHEL, but there might be a delay in receiving updates due to the nature of the community-driven development process.
  3. Branding: CentOS and RHEL have different branding and artwork, with RHEL featuring its distinctive “Red Hat” branding.

Personal Commentary

Having used both CentOS 7 and RHEL 7 extensively, I have found them to be equally reliable and stable operating systems. As a user, I appreciate the community-driven aspect of CentOS, which allows for greater flexibility and customization. However, the official support provided by Red Hat for RHEL is invaluable in enterprise environments, where timely updates and dedicated technical assistance are essential.

Both operating systems have extensive repositories of software packages, enabling administrators to easily install and maintain a wide range of applications. The command line interface, common to both CentOS 7 and RHEL 7, offers a powerful toolset for system administration and configuration.

Conclusion

In conclusion, CentOS 7 and RHEL 7 are closely related but have some important differences. While CentOS provides a free and open-source alternative to RHEL, RHEL offers enterprise-level support and regular updates. Choosing between the two ultimately depends on your specific needs and requirements. Whether you opt for CentOS or RHEL, you can be assured of a robust and reliable operating system for your server or workstation.
