Symptom & Impact

httpd returns 403 or blank pages while files appear readable from the shell.

Environment & Reproduction

Web files are mislabeled and blocked by SELinux policy in enforcing mode.

Root Cause Analysis

Run getenforce, ls -Z on document roots, and sudo journalctl -t setroubleshoot for AVC hints.

Quick Triage

Identify denials with sudo ausearch -m avc -ts recent and map them to target files.

Step-by-Step Diagnosis

Relabel content with sudo restorecon -Rv /var/www and add semanage fcontext rules if custom paths are used.

Solution – Primary Fix

Restart web service via sudo systemctl restart httpd and recheck access behavior.

Solution – Alternative Approaches

Confirm no new AVC denials appear and pages load successfully from remote clients.

Verification & Acceptance Criteria

Remove incorrect fcontext entries with semanage fcontext -d and relabel again.

Rollback Plan

Apply proper labels during deployment rather than disabling SELinux protections.

Prevention & Hardening

Track AVC volume trends from audit logs and alert on sudden spikes.

Related Errors & Cross-Refs

Embed semanage fcontext and restorecon tasks in playbooks for repeatable web deployments.
