Overview
Master Rocky Linux 9 administration. Install, configure, secure, and manage enterprise-grade Linux systems with networking, SELinux, firewalls, services, and production best practices.
The Problem
Enterprise Linux administration demands stability, security, and predictability. With the transition from traditional CentOS releases to CentOS Stream, many administrators faced uncertainty about long-term platform reliability.
Common challenges include:
- Migrating workloads from CentOS or other distributions
- Configuring secure firewall and SELinux policies
- Managing storage and filesystem layouts correctly
- Ensuring reliable backup and recovery strategies
- Deploying production services safely
Without structured guidance, production Linux systems can become inconsistent, insecure, or difficult to maintain.
The Solution
Rocky Linux 9 Administration provides a structured, step-by-step path to mastering enterprise Linux management.
You will learn how to:
- Install and configure Rocky Linux 9 properly
- Manage users, packages, and services efficiently
- Configure storage using LVM and RAID
- Secure systems with firewalld and SELinux
- Deploy web and database workloads confidently
- Implement logging, monitoring, backup, and recovery strategies
The result: reliable, hardened, and production-ready Rocky Linux infrastructure.
About This Book
Rocky Linux 9 Administration is a practical, production-focused guide to deploying, securing, and managing enterprise Linux systems with confidence.
When CentOS shifted direction, organizations needed a stable, community-driven enterprise Linux platform they could trust. Rocky Linux emerged as a reliable, RHEL-compatible successor—built for production environments and long-term stability.
This book provides the hands-on knowledge required to administer Rocky Linux 9 in real-world infrastructure settings—from initial installation to security hardening and production best practices.
