Symptom & Impact

Web requests return permission errors after moving content to a custom directory, causing outage for hosted applications on RHEL 8.

Environment & Reproduction

After changing Apache document root, service starts with systemctl but access fails. audit and journalctl logs show AVC denials under enforcing SELinux mode.

Root Cause Analysis

Filesystem labels on the new content path do not match expected httpd_t access rules, so SELinux blocks reads despite normal Unix permissions.

Quick Triage

Run getenforce, ausearch -m avc, and ls -Z on the target path. Confirm Apache unit health with systemctl status and port access through firewalld.

Step-by-Step Diagnosis

Identify denied class and context pairs, compare to expected httpd_sys_content_t labels, and validate current policy booleans relevant to web access.

Solution – Primary Fix

Apply persistent context mapping with semanage fcontext, run restorecon recursively, then restart service via systemctl and confirm AVC denials stop in journalctl.

Solution – Alternative Approaches

Enable required SELinux booleans for approved behaviors or keep content under default labeled paths to avoid custom policy complexity.

Verification & Acceptance Criteria

HTTP requests succeed, ausearch reports no new AVC denials for httpd, and configuration survives reboot without relabel drift.

Rollback Plan

Remove custom fcontext rules, restore original document root, restart Apache, and revert recent package or config changes using dnf history where applicable.

Prevention & Hardening

Include SELinux label checks in deployment pipelines and maintain policy-as-code controls for web content relocation tasks.

Related Errors & Cross-Refs

Similar issues appear with NFS-backed content, CGI execution denials, and nonstandard web ports. Link to your SELinux administration tutorial.
