CentOS 문제를 RHEL 호환 도구, SELinux 인식 방식 및 firewalld를 사용하여 분류하고 해결합니다.

centos-linux-triage란 무엇인가요?

이 스킬은 CentOS 시스템에서 발생하는 문제를 RHEL(Red Hat Enterprise Linux) 호환 도구를 사용하여 효과적으로 분류(triage)하고 해결하는 방법을 제공합니다. SELinux(Security-Enhanced Linux) 보안 정책을 인식하고 준수하는 방식으로 문제를 진단하며, firewalld 방화벽 관리 도구를 활용하여 네트워크 관련 이슈를 처리합니다. CentOS와 RHEL 간의 높은 호환성을 기반으로, 이 스킬은 개발자나 시스템 관리자가 CentOS 환경에서 발생하는 일반적인 문제(예: 패키지 설치 오류, 서비스 장애, 보안 정책 위반)를 신속하게 파악하고, 안전하고 표준화된 방법으로 수정할 수 있도록 안내합니다. 주로 Claude Code, Cursor, Codex와 같은 AI 에이전트 플랫폼에서 사용되며, 명령줄 인터페이스(CLI)를 통한 시스템 진단, 로그 분석, 구성 파일 편집 등의 작업을 자동화합니다.

centos-linux-triage은(는) 무엇을 하나요?

CentOS 문제를 RHEL 호환 도구, SELinux 인식 방식 및 firewalld를 사용하여 분류하고 해결합니다.

개요

이 스킬은 CentOS 기반 시스템에서 발생하는 다양한 이슈를 체계적으로 진단하고 해결하기 위한 가이드를 제공합니다. RHEL(Red Hat Enterprise Linux)과의 호환성을 활용하며, SELinux 및 firewalld와 같은 핵심 보안 및 네트워킹 도구를 존중하는 접근 방식을 채택합니다.

주요 기능

  • 문제 분류: 시스템 로그, 서비스 상태, 네트워크 연결 등을 분석하여 문제의 근본 원인 파악
  • RHEL 호환 도구 활용: yum, dnf, systemctl 등의 표준 RHEL/CentOS 명령어를 사용한 문제 해결
  • SELinux 인식 작업: SELinux 모드 확인, 정책 위반 로그 분석, 필요한 컨텍스트 조정
  • firewalld 관리: 방화벽 규칙 확인 및 추가, 영역(zone) 구성, 서비스 허용/차단

사용 예시

  1. 서비스 시작 실패 문제

    • systemctl status <service>로 서비스 상태 확인
    • journalctl -xe로 상세 로그 분석
    • SELinux 거부 로그 확인: ausearch -m avc -ts recent
    • 필요한 경우 firewall-cmd로 포트 개방

  2. 네트워크 연결 문제

    • firewall-cmd --list-all로 현재 방화벽 규칙 확인
    • ping 및 traceroute로 네트워크 경로 진단
    • SELinux 부울(Boolean) 값 확인: getsebool -a | grep http

지원 플랫폼

  • Claude Code
  • Cursor
  • Codex
  • 기타 AI 에이전트 플랫폼

참고 사항

  • 모든 명령어는 루트 권한 또는 적절한 sudo 권한으로 실행해야 합니다.
  • SELinux 및 firewalld 설정 변경 전 반드시 백업을 권장합니다.
  • RHEL 호환 명령어는 CentOS 7, 8, 9 및 최신 버전에서 동작합니다.

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

github/acquire-codebase-knowledge

Use this skill when the user explicitly asks to map, document, or onboard into an existing codebase. Trigger for prompts like "map this codebase", "document this architecture", "onboard me to this repo", or "create codebase docs". Do not trigger for routine feature implementation, bug fixes, or narrow code edits unless the user asks for repository-level discovery.

github/add-educational-comments

Add educational comments to the file specified, or prompt asking for file to comment if one is not provided.

github/agent-governance

Patterns and techniques for adding governance, safety, and trust controls to AI agent systems. Use this skill when: - Building AI agents that call external tools (APIs, databases, file systems) - Implementing policy-based access controls for agent tool usage - Adding semantic intent classification to detect dangerous prompts - Creating trust scoring systems for multi-agent workflows - Building audit trails for agent actions and decisions - Enforcing rate limits, content filters, or tool restrictions on agents - Working with any agent framework (PydanticAI, CrewAI, OpenAI Agents, LangChain, AutoGen)

github/agentic-eval

Patterns and techniques for evaluating and improving AI agent outputs. Use this skill when: - Implementing self-critique and reflection loops - Building evaluator-optimizer pipelines for quality-critical generation - Creating test-driven code refinement workflows - Designing rubric-based or LLM-as-judge evaluation systems - Adding iterative improvement to agent outputs (code, reports, analysis) - Measuring and improving agent response quality

github/agent-owasp-compliance

Check any AI agent codebase against the OWASP Agentic Security Initiative (ASI) Top 10 risks. Use this skill when: - Evaluating an agent system's security posture before production deployment - Running a compliance check against OWASP ASI 2026 standards - Mapping existing security controls to the 10 agentic risks - Generating a compliance report for security review or audit - Comparing agent framework security features against the standard - Any request like "is my agent OWASP compliant?", "check ASI compliance", or "agentic security audit"
