AlmaLinux
Enterprise-grade stability, open-source reliability
AlmaLinux is a community-driven, 1:1 RHEL-compatible Linux distribution designed for long-term stability and predictable performance. It inherits the enterprise-class reliability of the Red Hat ecosystem while remaining completely free and open source. With strong community backing and commercial support options available, it’s a popular choice for production servers, corporate workloads, and users wanting RHEL-level consistency without licensing costs.
Choose AlmaLinux if you need:
- Enterprise stability for business-critical applications
- Predictable updates and long-term lifecycle guarantees
- Compatibility with RHEL/CentOS ecosystems, tooling, and packages
- Strong security posture, including SELinux and regular security errata
When is AlmaLinux a Good Choice?
Running Web Servers
AlmaLinux’s stability and long-term support make it ideal for hosting Apache, Nginx, or other web servers with minimal downtime.
Hosting with cPanel / WHM or DirectAdmin
Because it’s binary-compatible with RHEL, AlmaLinux works seamlessly with major hosting control panels, offering reliable performance for shared and reseller hosting environments.
Managing Databases (PostgreSQL, MySQL / MariaDB)
Its predictable update cycle and enterprise-grade repository support make it a solid foundation for running production databases safely and efficiently.
Deploying Virtualization Stacks (KVM, libvirt)
AlmaLinux provides a stable kernel and strong hardware compatibility, making it an excellent host OS for virtualization platforms like KVM.
Running Enterprise Apps Built for RHEL-Based Systems
Any workload designed for RHEL runs smoothly on AlmaLinux thanks to its 1:1 binary compatibility, ensuring consistent behavior without licensing costs.
Orchestrating Containerized Workloads (Docker, Podman, Kubernetes)
With strong support for container tools and modern kernel features, AlmaLinux is well-suited for both lightweight container deployments and full Kubernetes clusters.
AlmaLinux Requirements
AlmaLinux is lightweight, but enterprise workloads often benefit from more headroom.
Minimum practical resources:
- 1–2 vCPU
- 2 GB RAM
- 20 GB SSD
Recommended for production:
- 2–4 vCPU
- 4–8 GB RAM
- 40+ GB SSD, depending on workload
Workload suggestions:
- Database servers: add more RAM
- Web servers: prioritize CPU and I/O
- Control panels (cPanel/WHM): aim for 4 GB RAM minimum
AlmaLinux License & Costing
AlmaLinux is fully open-source with no licensing fees.
Everything included in the distribution is free to use, redistribute, and modify.
AlmaLinux Installation Tips
AlmaLinux is lightweight, but enterprise workloads often benefit from more headroom.
Update Immediately After Provisioning
Run dnf update -y to ensure your system starts with the latest patches and security fixes.
Create a Secure Admin User
Add a non-root sudo user right away to maintain safer, best-practice server management.
Enable & Configure Your Firewall Early
Use firewalld to block everything except required service ports before going live.
Harden SSH Access
Set up key-based authentication, disable password logins, and restrict SSH access to trusted IPs when possible.
Install Essential Protection & Monitoring Tools
Tools like fail2ban, system monitoring agents, and resource metrics help maintain long-term stability.
Frequently Asked Questions
What are the AlmaLinux system requirements?
For most deployments, the OS runs comfortably on modest hardware, but performance scales noticeably with more CPU, RAM, and disk throughput. Light services operate fine on small cloud instances, while heavier environments (like databases or control panels) gain clear benefits from extra memory and faster storage.
What are the different AlmaLinux versions?
Alma Linux follows RHEL’s release cycle, so each major version (e.g., 8.x, 9.x) mirrors RHEL’s features, compatibility, and lifecycle. Each major stream receives long-term support, with minor point releases providing security updates and stability improvements.
AlmaLinux vs Debian: What’s the difference?
Debian leans toward a traditional, minimalist philosophy with a vast repository and a slower update cadence. AlmaLinux, by contrast, aligns closely with enterprise-style configurations and workflows. Debian is ideal for those wanting a conservative, community-driven environment; AlmaLinux suits those who prefer structured, enterprise-oriented ecosystems.
AlmaLinux vs Ubuntu: What’s the difference?
Ubuntu tends to favor rapid evolution, broad hardware availability, and developer-oriented conveniences. AlmaLinux emphasizes a steady, predictable operational model. Ubuntu often appeals to teams who iterate quickly; AlmaLinux appeals to environments prioritizing stability above all else.
