Symptom & Impact

Web app returns 403 forbidden even though filesystem permissions seem correct.

Environment & Reproduction

Appears after moving document root to custom path.

systemctl status httpd
curl -I http://localhost

Root Cause Analysis

SELinux context on web content does not match httpd policy expectations.

Quick Triage

Check SELinux status, context labels, and recent AVC events.

sestatus
ls -lZ /srv/www/app
ausearch -m avc -ts recent

Step-by-Step Diagnosis

Correlate 403 events with audit denials and service logs.

journalctl -u httpd -n 100
sealert -a /var/log/audit/audit.log

Solution – Primary Fix

Assign proper SELinux file context and relabel content directory.

sudo semanage fcontext -a -t httpd_sys_content_t '/srv/www/app(/.*)?'
sudo restorecon -Rv /srv/www/app
sudo systemctl restart httpd

Solution – Alternative Approaches

For writeable directories, use httpd_sys_rw_content_t only where required.

Verification & Acceptance Criteria

HTTP endpoint responds with 200 and no new AVC denials are logged.

curl -I http://localhost
ausearch -m avc -ts recent

Rollback Plan

Remove custom fcontext mapping if incorrect and relabel back to defaults.

Prevention & Hardening

Document approved web root paths and SELinux types in deployment pipelines.

Related Errors & Cross-Refs

Can overlap with missing execute bits and restrictive Apache Directory directives.
