Centos Linux Triage
Diagnose CentOS or RHEL-compatible server failures with numbered triage, remediation commands, and post-change validation.
Overview
centos-linux-triage is an agent skill for the Operate phase that diagnoses and resolves CentOS issues with RHEL-compatible commands, SELinux awareness, and firewalld checks.
Install
npx skills add https://github.com/github/awesome-copilot --skill centos-linux-triageWhat is this skill?
- Structured output: Summary, numbered Triage Steps, Remediation Commands, Validation, Rollback/Cleanup
- Uses RHEL-compatible tooling: systemctl, journalctl, dnf/yum, and log inspection
- Calls out SELinux and firewalld considerations on remediation paths
- Copy-paste-ready commands with verification after each major change
- Optional inputs for CentOS version, problem summary, and constraints
- Five numbered instruction steps in the skill workflow (confirm release, triage, remediate, verify, SELinux/firewalld, ro
Adoption & trust: 8.4k installs on skills.sh; 34.6k GitHub stars; 2/3 security scanners passed (skills.sh audits).
What problem does it solve?
Your CentOS server is misbehaving and you need ordered triage steps—not random forum commands that ignore SELinux or firewall state.
Who is it for?
Solo builders maintaining CentOS or Stream hosts who need systemd, dnf/yum, and security-module-aware incident response in one pass.
Skip if: Pure local macOS or Windows desktop debugging, managed PaaS-only deploys with no SSH access, or greenfield app feature implementation.
When should I use this skill?
Triage and resolve CentOS issues using RHEL-compatible tooling, SELinux-aware practices, and firewalld when production or staging Linux hosts misbehave.
What do I get? / Deliverables
You receive a documented triage path, remediation commands, validation checks, and rollback steps aligned with CentOS/RHEL practices.
- Numbered triage and remediation command blocks
- Post-change validation commands
- Rollback or cleanup steps when remediation fails
Recommended Skills
Journey fit
Production Linux triage belongs in Operate when services, firewalls, or packages break after you have already shipped. The skill targets OS-level infrastructure—systemd, package managers, SELinux, and firewalld—not application feature code.
How it compares
Incident-focused Linux triage playbooks—not a generic “learn Linux” course or a cloud-only Terraform skill.
Common Questions / FAQ
Who is centos-linux-triage for?
Indie devops-ish founders and small teams who SSH into CentOS or RHEL-family servers and need expert-style triage without a dedicated SRE.
When should I use centos-linux-triage?
In Operate (infra) when services fail to start, packages conflict, firewalls block traffic, or logs show SELinux denials on a CentOS host.
Is centos-linux-triage safe to install?
The skill instructs privileged system commands—you must review proposed changes before running them; check the Security Audits panel on this Prism page before install.

READMESKILL.md - Centos Linux Triage
# CentOS Linux Triage You are a CentOS Linux expert. Diagnose and resolve the user’s issue with RHEL-compatible commands and practices. ## Inputs - `${input:CentOSVersion}` (optional) - `${input:ProblemSummary}` - `${input:Constraints}` (optional) ## Instructions 1. Confirm CentOS release (Stream vs. legacy) and environment assumptions. 2. Provide triage steps using `systemctl`, `journalctl`, `dnf`/`yum`, and logs. 3. Offer remediation steps with copy-paste-ready commands. 4. Include verification commands after each major change. 5. Address SELinux and `firewalld` considerations where relevant. 6. Provide rollback or cleanup steps. ## Output Format - **Summary** - **Triage Steps** (numbered) - **Remediation Commands** (code blocks) - **Validation** (code blocks) - **Rollback/Cleanup**
