How to choose a Linux distro for servers
Support length comes first
On a server, the most important number is how long the release receives security updates, because reinstalling or upgrading production systems is costly. Ubuntu LTS releases are supported for five years by default, with extended support available through Ubuntu Pro. Debian stable gets about five years including its LTS period. Red Hat Enterprise Linux and compatible distributions are supported for about ten years per major version.
Our end-of-life tracker lists the exact dates for every supported release.
Debian and Ubuntu, or the Red Hat family?
Debian and Ubuntu dominate cloud images and web hosting, use APT, and have the largest pool of tutorials. The Red Hat family, which includes Red Hat Enterprise Linux, AlmaLinux, Rocky Linux, and CentOS Stream, uses DNF and is common in enterprises that need vendor certification for software such as databases and ERP systems. AlmaLinux and Rocky Linux offer RHEL compatibility without a subscription.
Containers and small systems
Alpine Linux is popular as a base for container images because it is very small. For hosts that mostly run containers, a minimal install of Debian, Ubuntu, or a RHEL-compatible system is usual. Raspberry Pi OS is the simplest choice for home servers on a Raspberry Pi.
Choose what your team can support
In practice the best server distribution is the one your team already knows how to secure, monitor, and recover. Consistency across machines matters more than small technical differences.
Servers: common questions
What is the most used Linux server distribution?
Ubuntu, Debian, and Red Hat Enterprise Linux derivatives are the most common on servers and in cloud images.
What replaced CentOS Linux?
CentOS Linux ended in 2024. AlmaLinux and Rocky Linux are the most common drop-in replacements; CentOS Stream continues as the upstream of RHEL.
Is Debian or Ubuntu better for servers?
Both are excellent. Debian is community-run, very conservative, and has no commercial add-ons. Ubuntu LTS has newer kernels, commercial support, and optional extended security maintenance. Pick the one your tooling and team already use.
Is AlmaLinux or Rocky Linux better?
Both are free RHEL-compatible distributions that started after CentOS Linux ended, and both are suitable for production. The differences are governance and support options rather than technical capability.
What is the best Linux distro for a home server?
Debian and Ubuntu Server are the most common choices for home servers and NAS builds because of their long support and huge documentation. On a Raspberry Pi, use Raspberry Pi OS Lite.
