Symptom & Impact

A custom application on RHEL 7 fails after deployment because SELinux file labels do not match required policy types.

Environment & Reproduction

Service fails to read or execute files under nonstandard directories despite correct UNIX ownership and mode bits.

Root Cause Analysis

Files copied without preserving labels, new deployment path missing persistent fcontext rule, or accidental relabel operations.

Quick Triage

Check getenforce, run ls -Z on application directories, and verify service state with systemctl status and service status.

Step-by-Step Diagnosis

Inspect /var/log/audit/audit.log and journalctl for AVC denials referencing mislabeled files.

Solution – Primary Fix

Record current labels and define persistent mappings using semanage fcontext before relabeling with restorecon.

Solution – Alternative Approaches

Apply correct context patterns via semanage fcontext -a, run restorecon -Rv on paths, and restart the service.

Verification & Acceptance Criteria

This issue is SELinux-specific, but firewalld should still be checked if service also exposes network listeners.

Rollback Plan

Confirm process start and file access behavior with systemctl status and targeted functional checks.

Prevention & Hardening

Remove incorrect fcontext rules and restore previous labels if newly applied contexts are too broad.

Bake semanage rules into deployment automation and run post-deploy restorecon in controlled steps.
