Official Documentation
The official SELinux documentation is the most authoritative resource, covering fundamental concepts (MAC, TE, RBAC), configuration files (e.g., /etc/selinux/config), command syntax (e.g., sestatus, setenforce), and advanced policy management. It is regularly updated to reflect changes in CentOS releases and is essential for understanding SELinux’s role in system security.

Community Tutorials
Websites like and 筋斗云 offer step-by-step guides tailored to CentOS users. Topics include enabling/disabling SELinux (temporary/permanent), configuring policies with semanage and audit2allow, and troubleshooting common issues (e.g., missing dependencies, kernel compatibility). These tutorials often include practical examples (e.g., allowing Apache to access custom ports) and are suitable for beginners to intermediate users.

Video Tutorials
Video platforms host beginner-friendly tutorials (e.g., “通俗易懂的Linux之CentOS7.x教程”) that visually demonstrate SELinux setup and configuration. Videos are particularly helpful for visual learners, showing commands in action and explaining complex concepts (e.g., security contexts, policy modules) through demonstrations.

Books
Books such as 《Apress Foundations of CentOS Linux, Enterprise Linux On the Cheap》 provide comprehensive coverage of SELinux within the CentOS ecosystem. They include chapters on installation, configuration, and best practices, making them suitable for readers who prefer structured, in-depth learning over scattered online resources.

Tools & Utilities
Key tools like semanage (for managing ports/contexts), audit2allow (for generating custom policies from logs), and setools (for analyzing policies) are critical for managing SELinux on CentOS. The official documentation and community tutorials often include practical examples of using these tools to solve real-world problems (e.g., resolving “AVC denied” errors).

Best Practice Guides
Guides focused on best practices (e.g., enabling SELinux in enforcing mode, optimizing policy rules for performance, regularly reviewing audit logs) help administrators use SELinux effectively without compromising system usability. These guides emphasize backup strategies (before making changes) and monitoring (via /var/log/audit/audit.log) to ensure system stability and security.
