Linux

For an alternative, when I was looking into server os's, from what I can tell RHEL (Red Hat Enterprise Linux) is the go to since it's stable. That said RHEL is not free, so what people use to do is get a free OS which is down stream to RHEL, that's your Alma and Rocky Linux.

However back in 2023 IBM made some changes, and now Alma and Rocky had to rebase off of CentOS Stream which is what RHEL is based off of.

For all intent and purpose I'd recommend using Debain, but Alma and Rocky are alternatives you may want to look into. Personally using Alma and outside of the learning curve of using a RHEL based OS, it has been quite stable.

Debian as host and Incus + Alpine for containers

My favorite Server OS is Alpine Linux. Because its small, easy to use.

Ofcourse its not using the standard GLIBC system, but these days you can run almost anything in docker so thats less of a problem.

Debian, with containers for each app based on Alpine linux.

Surprised there's not more people saying Nixos.

Its a bit annoying to learn, but once you get the hang of it its impossible to break, and amazing if you have multiple server's doing similar things

Debian is a great choice. I'm on Debian and it is solid.

I do have one I like better: I'm transitioning to Fedora IoT from Debian for my homelab stuff. I like using their atomic desktop distros, I want to understand them better, and it seems like a great combination of recent kernel and system stability.

When I’m prototyping some model deployment/application/backend, I choose Ubuntu. I’ve also chosen Debian Stable before.

When te decision has been made to actually write the fucking thing for real enterprise deployment, it’s always Alpine Linux so that we have fine control over literally every aspect of the image.

I’d never recommend Alpine for any other use case, tbh.

I literally once rented a VPS, installed Debian 12, configured automatic updates, installed tor, set the max limit to the VPS limit, enabled the tor relay server.

And now I am unable to login and that thing is just running lol. For the good of the Tor network?!

I am thinking about Fedora IOT or uBlue Core. A lot of stuff needs Docker, even though I think SELinux and secure packages make more sense.

Also keeping an eye on CentOS bootc, which is way more stable but continuously integrated fixes, atomic updates, reversible...

MicroOS and Debian

In 2001 we examined the packaging format of debian and found it lacked a validation feature available in RPM. This killed debian and all derivatives as an option by the build group of the unix vendor I worked with -- please tell me you understand why validation is a pivotal feature for build. The fact the validation carries hard sigs all the way down made the security group happier too. This hasn't changed.

So I'm running CentOS now, Rocky later, and PCLinuxOS once they get a good packer template.

We use ubuntu at work on about 30 servers. It was a mistake made years ago, I’m hoping to switch them to Debian next year. Ubuntu being a Debian based distro means at least 90% of ansible code will work without changes.

Nice overview of enterprise linuxes (or is that Linii in plural?): https://tuxcare.com/resources/learning/enterprise-linux/

I use Debian on my home server and CentOS on my VPS.

Debian.

Proxmox (which is heavily Debian) if the use case is to host VMs and/or LXC containers. Debian on those.

I use FreeBSD 😅

debian and rhel.

if you can do it on debian you can do it on one of the derivatives and same for rhel.

its amazing how many people still don't know that you can run a handful of rhel machines for free.

Ubuntu LTS.

It has the option for PPAs when the distro doesn't offer packages or recent package updates but the upstream project does.

It's a well-established and stable distro.

Gentoo for most of my personal machines. I currently have about 12 that I use actively (bare metal + virtual).

(Among other things,) I currently use Ceph across 3 servers for storage; Buildah/Podman/Skopeo, LXD, and Libvirt for virtualization; Git for versioning/a simple way to keep certain things in sync; and Saltstack to automate updates.

I have a dedicated virtual machine for building software packages which shares those built packages (currently via Virtiofs) with a LXD instance that exposes them over HTTP for my other machines to download so software only needs to be built/packaged once.

Debian. When I have time to mess about with server stuff, I want to be doing the thing I want to do rather than fixing whatever broke in the most recent set of updates

Debian is a pretty safe choice overall but and I’m sure I’m going to get downvoted like crazy but arch has been a fantastic server OS for me for a while. Debian is pretty hands off but I have some pretty unorthodox requirements/hardware setups and the combination of the wiki and such a wide range of packages supported has enabled me to use the hardware to its fullest potential. Also rolling release lts kernel is pretty dope.

I have a (personal use) server with debian for some minecraft servers.

during winter i use gentoo, so the cpu keeps the room cozy

What will you be doing with your server?

Proxmox. VMs and containers are great, especially when you're learning

What we use in my office, depends on the type of servers:

• For virtual server (we made a golden template of it) we use Debian 12
• For virtualization host/ganeti cluster we use Debian 11
• For NAS, we use OpenMediaVault (based on Debian)

I run Rocky Linux 9 on an HPC environment for the package stability and 10 years of support. I also prefer the Red Hat-esque management ecosystem (ie, Foreman) to the others I’ve tried (but it still leaves a lot to be desired).

I am no fan of Red Hat’s corporate shenanigans though, and if it weren’t for the associated tech debt, I might consider switching to Debian or Ubuntu. I’ve run both at previous jobs, but the support lifecycle has come back to haunt us every time.

NixOS. Ubuntu when I just want to test something quickly.

Debian

Debian

lots of debian. its debian all the way down.
