Rocky Linux

Overview

Rocky Linux is a community-driven, open-source Linux distribution created as a direct successor to CentOS Linux, following the shift of CentOS from CentOS Linux to CentOS Stream. Rocky Linux aims to provide a stable, secure, and free alternative for users who relied on CentOS Linux for their server needs. It shares the same goals and principles as CentOS, focusing on compatibility with Red Hat Enterprise Linux (RHEL) and providing a reliable platform for enterprise applications.

Why Choose Rocky Linux?

CentOS Continuation: Rocky Linux is intended to continue the traditional CentOS Linux experience, providing a stable and familiar environment for CentOS users.

Stability: Rocky Linux emphasizes stability and long-term support, making it suitable for production environments and critical applications.

Community-Driven: Just like CentOS, Rocky Linux is backed by a community of developers and users who contribute to its development and provide support.

Binary Compatibility: Rocky Linux aims to be binary-compatible with RHEL, allowing users to seamlessly transition their RHEL or CentOS workloads to Rocky Linux.

Security: Rocky Linux receives security updates and patches, ensuring a secure operating system for your infrastructure.

Getting Started

Update Packages: After deploying Rocky Linux, start by updating the system packages using the package manager (typically dnf).

Network Configuration: Configure network settings, including IP address, subnet mask, gateway, and DNS servers, to match your network requirements.

User Management: Create user accounts, set passwords, and manage user privileges using commands like useradd, passwd, and sudo.

Firewall Setup: Configure the firewall using firewalld or other tools to control incoming and outgoing network traffic.

Install Software: Use the dnf package manager to install the necessary software packages for your server's intended purpose, such as web servers, databases, or applications.
