Sysadmins, what GNU/Linux distribution 🐧 runs on your server(s)?

@carlchenet I wanted to use CentOS in the first place because it's a RedHat clone (RH is often used in corporations). But, I needed to reinstall one of my servers and I wanted to use Proxmox, but it didn't work well so I came back to Debian since

@carlchenet But, I still use CentOS as my main OS for servers. The Debian one is more like an exception to my rule ;)

Debian meilleure distribution pour avoir un maximum de communauté sans avoir d'entreprise qui décide dans son coin. Stabilité à toute épreuve et team sécurité au top. On a un parc de 1200 serveurs Debian et juste un peu de Raspian ou PfSense Opnsense à côté

@Bridouz I'm curious (again), any specific reason for this choice?

@carlchenet Lightweight, minimal and multi-platforms.

PS: I use it on a Rpi at home, no jobs involved.

@carlchenet for my owr I use Debian, but my companie use centOS

@Sp3r4z I'm so surprised to see the important use of Centos

@linuxmario not really, I think it's more about years of support and maybe being related to RedHat


@carlchenet it's probably because of RedHat source. Like "nice, a free red hat" (free as beer).
And long time support


50/50 between debian and ubuntu servers.

Formerly, I used CentOS for some servers. It was for stability purposes on HPC system. However, I moved to debian on these systems, in order to get more updated packages.
Nevertheless, I know that many people are still using CentOS, because of certified drivers/modules/packages from RedHat (sometimes, debian derivatives are not working at all). For example, in HPC, ib drivers are certified for RedHat (and therefore, for CentOS too).

@Fritange ok, nice one, very interesting, I didn't know for the driver part, thanks 👍

@ScriptFanix 🤣 so many distros, seems quite difficult to maintain 😅

Gnu Guix parce que c'est uniquement pour du perso, que je suis contributeur et amoureux du modèle déclaratif pour la configuration :)

@carlchenet I've sysadmined on one level or another for hundreds of clients over the years. I dont think I've recently seen a single server that runs RedHat proper in years. I wonder why that is even on the list.

Seems the most popular would be debian, ubuntu and CentOS.. for me I'm most likely to run ArchLinux though

@freemo yes, it usually is used by large companies. License fees omg 😅

@carlchenet No doubt some companies out there do. But even of the large companies I have admined for I never came across it in modern times

@freemo yeah, I haven't been working with it in years neither. I worked with it mostly in finance/banking environment.

@carlchenet Thats actuallty not surprising. Finance and banking tend to be a decade behind on tech it seems.

Depending on whether you ask me on my job or private me, it is CentOS or NixOS


CentOS for stable stuff, fedora server for the test homelab

@bortzmeyer je vois pas d'options pour faire un sondage à choix multiple 😓 mais j'ai reçu plein de réponses indiquant un second choix 😆

@carlchenet for servers that are supposed to run for a bit longer. Eg I set up our development server back in 2008 and it‘s still humming nicely.
CentOS for production servers because we swap machines at their end of warranty anyway. This gives a chance for a fresh CentOS Install every 5 years.

@dirkolmes as long as you can install security patches, that's great 👍

@carlchenet is a rolling release. Due to its source-based nature I expect security fixes much quicker than for Package distros.

@carlchenet I use Void Linux and Devuan.

I do not use systemd-linux, which is the proper name of "Gnu" Linux. Debian, Redhat - all rely far more on Systemd than Gnu. Gnu provides a compiler, but those distributions don't use, nor do they support, the Gnu init system.

(I don't use it either; compared to runit, it's overcomplex. )

@carlchenet Oh, I should also mention that for virtualization, I use xen - and _can_ use kvm, but I prefer xen (:

Under that, I am using - again - devuan for most items (stability) and a few void (development things.)
also doing some work with Openbsd, but you asked about Linux (:

I _have_ run into a few issues with devuan that I have not worked through for php7 - mainly that the current debian packages rely on systemd for php7-fpm. I am not the biggest fan of php in the first place, but will need to do something about a php7 package for devuan that is up to date and NOT requiring systemd. Because we should have the choice of init systems - even if lots of people don't care, those that do, or need to know what is going on with their servers with fine grained control...)

For the Xen setup, I've used both Alpine and Devuan. I prefer the Devuan setup (:

(Devuan is debian - just without systemd. Some folks said it would never last, but it has (: )

work-related servers - Ubuntu / CentOS
personal servers - Debian. Arch on my personnal servers. Mostly Debian for work ones.

@Darks never tested Arch 🥺 I should give it a try sometimes !

@carlchenet Au taf on utilise majoritaire du Debian (un ou deux milliers d’instances je dirais, sur quelques centaines de dédiés). Quelque CentOS et Ubuntu traînent pour raisons historiques, mais on refuse d’en installer ou reprendre d’autres.

En perso, c’est du full Arch, simplement parce que ça demande pas beaucoup de maintenance pour rester à jour, et que j’en ai l’habitude.

@Steve12L I'm a bit surprised to see the current results indeed 🤔
