The Apache HTTP Server (commonly known as Apache) is one of the most trusted and feature-rich open-source web servers. When deployed on Rocky Linux 9—a community-supported, RHEL-compatible enterprise OS—Apache benefits from exceptional stability, long-term support, and seamless integration with modern Linux server environments.
Why Use Apache on Rocky Linux 9?
Rocky Linux 9 is a downstream rebuild of Red Hat Enterprise Linux 9, with the same package structure, ABI compatibility, and security features. It offers a rock-solid platform for hosting Apache in production systems, including:
- Linux Kernel 5.14 LTS
- SELinux enabled by default
- dnf with modular stream support
- systemd 250+ for service management
- OpenSSL 3.0+ for modern TLS/SSL
This makes it suitable for regulated industries, high-availability hosting, and cloud-native web applications.
Apache HTTP Server – Core Features on Rocky Linux 9
Apache on Rocky Linux 9 is capable of running diverse workloads with a focus on configurability and security:
| Feature | Description |
|---|---|
| Virtual hosting | Host multiple websites/domains from a single server |
| modular design | Use only the modules you need (mod_ssl, mod_rewrite, mod_proxy, etc.) |
| HTTPS support | Strong TLS/SSL with OpenSSL 3.0 and mod_ssl |
| Reverse proxy support | Built-in modules for load balancing and API proxying |
| .htaccess configuration | Per-directory overrides for access control, redirects, rewrites |
| Multiprocessing modules | Support for worker, event, and prefork MPMs |
| Logging and observability | Integrated with journald, logrotate, and custom log formats |
Use Cases and Scenarios
Apache on Rocky Linux 9 is suited for:
- LAMP stack deployments (Linux, Apache, MariaDB, PHP)
- CMS platforms like WordPress, Drupal, Joomla
- Reverse proxy and SSL offloading in microservices architecture
- Dynamic web applications using PHP, Python (WSGI), or CGI
- Security-sensitive environments where SELinux and audit logging are needed
- Enterprise dev/test/staging environments
Apache vs Other Web Servers on Rocky Linux 9
| Feature | Apache | Nginx | OpenLiteSpeed |
|---|---|---|---|
| Dynamic content support | mod_php, php-fpm, CGI | php-fpm only | Native LSAPI/PHP |
| .htaccess override | ✅ Yes | ❌ No | ⚠️ Partial |
| SSL/TLS support | ✅ mod_ssl, OpenSSL 3.0 | ✅ Excellent | ✅ Strong |
| Performance (static) | Moderate | High | Very High |
| Reverse proxy/load balancing | ✅ mod_proxy family | ✅ Native | ⚠️ Basic |
| System integration | Excellent with SELinux, systemd, dnf modules | Excellent | Requires tuning |
Apache excels when deep per-directory configuration, plugin compatibility, or legacy application support is required. Nginx and OpenLiteSpeed may be better suited for high-throughput static content or API gateway roles.
Integration with Rocky Linux 9 Toolchain
Apache benefits from a full range of enterprise-grade system tools available in Rocky Linux:
- ✅ systemd: Simplified management with
systemctl - ✅ SELinux: Apache runs under confined
httpd_tcontext for secure execution - ✅ FirewallD: Predefined
httpandhttpsservices for fast port configuration - ✅ dnf modules: Enable custom PHP streams (e.g., PHP 8.1, 8.2)
- ✅ logrotate: Manage access and error logs on a schedule
- ✅ Podman: Run Apache in containers without needing Docker
Apache is also compatible with Cockpit, Rocky’s browser-based server management interface, enabling easier monitoring and virtual host control.
Security and Maintenance Advantages
Rocky Linux 9 provides security-focused defaults that align well with Apache:
- Enforcing SELinux: Prevents unauthorized access to system files and ports
- Timely CVE patches: Backported security fixes with minimal impact on configuration
- TLS 1.3 Ready: OpenSSL 3.0 support with modern cipher suite configurations
- Role-based access control via tools like
polkitor LDAP
Administrators benefit from predictable behavior, long support windows, and community-driven stability similar to what CentOS once offered.
Apache in Cloud and Virtualized Environments
Apache on Rocky Linux 9 scales well in:
- Cloud VPS platforms (e.g., AWS, Shape.Host, Linode)
- Podman containers
- Load-balanced clusters
- Service-oriented architectures using reverse proxy modules
Pairing Apache with MariaDB, Redis, and PHP-FPM yields a stable, performant backend stack for modern applications while maintaining full compatibility with enterprise tooling.
Apache HTTP Server on Rocky Linux 9 offers a mature, secure, and highly configurable web platform backed by the reliability of an enterprise-grade Linux distribution. Ideal for everything from traditional LAMP stacks to reverse proxy gateways, Apache remains a cornerstone of web infrastructure.
Rocky Linux 9 enhances Apache with robust SELinux confinement, systemd reliability, and future-proof OpenSSL support—making it a great choice for developers, sysadmins, and organizations looking for a CentOS alternative with long-term viability.
Step 1: Create a Shape.Host VPS
Go to https://shape.host and log in.
Click “Create” → “Instance”.
Choose your preferred location.
Select Rocky Linux 9 (64-bit) as the OS.
Pick a plan with at least 1 CPU and 1 GB RAM.
Click “Create Instance”.
Copy the instance’s IP from the Resources section.
Step 2: Connect to Your Rocky Linux VPS
Use SSH to log in:
ssh root@your-server-ip
Step 3: Update System and Install Apache
Update all packages:
dnf update
Install Apache:
dnf install httpd
Step 4: Start and Enable Apache
Start the web server:
systemctl start httpd
Enable Apache to launch at boot:
systemctl enable httpd
Check its status:
systemctl status httpd
Step 5: Configure Firewall
Unmask and start firewalld:
systemctl unmask firewalld
systemctl enable firewalld
systemctl start firewalld
Allow HTTP, HTTPS, and SSH traffic:
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
firewall-cmd --permanent --add-service=ssh
firewall-cmd --reload
Visit http://your-server-ip in your browser — you should see the Apache test page.
Step 6: Replace Default Web Page
Add a custom HTML welcome message:
cd /var/www/html
echo "<h1>Hello from Apache on Rocky Linux 9</h1>" > /var/www/html/index.html
Reload your browser at:
http://your-server-ip
Step 7: Uninstall Apache (Optional)
If you want to remove Apache:
dnf remove httpd
dnf autoremove
