12 Best Linux Server Operating Systems and Who Should Use Them

Moe Long 13-02-2017

Linux operating systems are exceptionally prevalent and wide-ranging. While certain Linux distros are suitable for power users, others are simpler, and perfect for switching from Windows. Linux distributions often benefit from strong community resources.


Although the Linux operating systems offer excellent desktop environments, Linux can be excellent for server set ups as well. Linux typically offers enhanced permissions, increased flexibility, and stability.

Therefore, Linux distros are ideal server landscapes. Check out the 12 best Linux server operating systems and who should use them.

What Is a Linux Server Operating System?

What differentiates a Linux server operating system from a general Linux distribution? Consider server hardware. Servers are essentially computers with specialized specifications. For instance, server hardware ensures maximum uptime, efficiency, and security. Additionally, servers balance computing power with power consumption. Similarly, Linux server operating systems prioritize security and resource consumption.

A Linux server operating system serves content to client devices. Accordingly, server operating systems feature tools for simple server creation. Because servers commonly run headless, the graphical user interface (GUI) in a Linux server operating system remains less important.

According to IDC, hardware sales data indicates that 28 percent of servers are Linux-based. However this likely doesn’t account for home labbers. While there are dedicated Linux server operating systems, you may roll your own. The key here is to use a Long Term Service (LTS) iteration and install your desired software. LTS flavors provide stability and a longer support cycle.

1. Ubuntu Server

12 Best Linux Server Operating Systems and Who Should Use Them ubuntuserver 640x195

Ubuntu is arguably the most well-known Linux operating system. With a plethora of Ubuntu derivatives, it’s a stable distribution. Ubuntu and its variants offer excellent user experiences. Ubuntu Server is available in two versions: LTS and a rolling-release. The LTS Ubuntu Server release boasts a five year support cycle. Although the support cycle isn’t five years, the non-LTS variant features nine months of security and maintenance updates.

While Ubuntu and Ubuntu Server are pretty similar, Server offers different amenities. Notably, Ubuntu Server provides OpenStack Mitaka, Nginx, and LXD. Such inclusions cater to system administrators. Using Ubuntu Server, you can spin up web servers, deploy containers, and more. Moreover, it’s server-ready out-of-the-box.


Although it’s not a server distro, Ubuntu LTS does feature a five year support cycle. I’m currently using Ubuntu 16.04 LTS to run a dedicated Plex server as well as a Linux game server. LTS distros can function perfectly well as Linux server operating systems. You’ll just need to install server software on your own.

Who should use this: If you’re new to Linux or server operating systems, Ubuntu is a great choice. Ubuntu remains one of the most popular Linux distros in part because of its user friendliness.

SUSE Linux debuted in 1993. In 2015, open-source variant openSUSE migrated toward SUSE Linux Enterprise (SLE). There are two openSUSE derivatives: Leap and Tumbleweed. Leap features longer release cycles whereas Tumbleweed is the rolling release. Tumbleweed is better for power users with its up-to-date packages like the Linux Kernel and SAMBA. Leap is better for stability. Updates bolster the operating system.


Default tools posit openSUSE as a fantastic Linux server operating system. openSUSE includes openQA for automated testing, Kiwi for Linux image deployment on several platforms, YaST for Linux configuration, and the comprehensive package manager Open Build Service. In abandoning its previous nine month release cycle and focusing on stability like SLE, openSUSE became a viable Linux server environment. CIO even dubbed openSUSE “…the CentOS and Debian of SUSE.”

Who should use this: openSUSE is more suited to power users like system administrators. It’s great as a web server, home server, or home server/web server combo. System administrators benefit from tools like Kiwi, YaST, OBS, and openQA. The versatility of openSUSE makes it one of the best Linux server operating systems. In addition to solid server capabilities, openSUSE does sport a lovely desktop environment. For more basic servers, openSUSE is usable but a bit overkill. Still not convinced?

If you did a double take when reading “Oracle Linux,” you’re not alone. Oracle Linux is a Linux distribution powered by tech giant Oracle. It’s available with two kernels. One features the Red Hat Compatible Kernel (RHCK). This is the same kernel as found in Red Hat Enterprise Linux (RHEL). Oracle Linux is certified to work on lots of hardware from the likes of Lenovo, IBM, and HP. Oracle Linux features Ksplice for enhanced kernel security. There’s also support for Oracle, OpenStack, Linux containers, and Docker. It’s branded with an Oracle theme including an Oracle penguin.


There is support, but it’s paid. Unless you’re running Oracle Linux in an enterprise environment it’s not worth the price. If you need to spin up a public or private cloud, Oracle Linux is a stellar server operating system. Alternately, try Oracle Linux if you simply need the Oracle-branded Linux penguin.

Who should use this: Oracle Linux is best for datacenters or creating clouds with OpenStack. More advanced home server users and enterprise-level settings are best for Oracle Linux.

4. Container Linux (Formerly CoreOS)


CoreOS rebranded to Container Linux in 2016. As the name suggests, Container Linux is a Linux operating system built for deploying containers. There’s a concentration on simplifying containerized deployments. Container Linux is a superb operating system for secure, highly scalable deployments. Clustered deploys are easy and this distro includes means for service discovery. There’s documentation and support for Kubernetes, Docker, and rkt.

However, there’s no package manager. All apps must run inside containers, so containerization is mandatory. Nevertheless, if you’re working with containers Container Linux is the best Linux server operating for a cluster infrastructure. It offers an etcd which is a daemon running across each computer within a cluster. You’ve got install flexibility too. In addition to an on-premise installation, you can run Container Linux on virtualization mediums like Azure, VMware, and Amazon EC2.

Who should use this: Container Linux is best for servers in a cluster infrastructure or with containerized deploys. This likely won’t mean the average home labber. But with official Docker images from the likes of Plex, Container Linux can function as anything from a basic home media server to complex clustered set up. Ultimately, use Container Linux if you’re comfortable with containers. Along with openSUSE, Container Linux is one of the best new and updated Linux operating systems The Newest Linux Operating Systems for Every Niche Linux operating systems are constantly updated, with some are more substantial than others.

CentOS provides a stable environment. It’s an open-source derivative of Red Hat Enterprise Linux (RHEL). Thus, CentOS delivers an enterprise-class server experience. The Red Hat sponsored operating system uses the exact source code as found in RHEL. CentOS employs the RPM package manager. In 2010, survey data found that about 30 percent of all Linux servers operated on CentOS. There’s a reason: it’s a very stable server environment with Red Hat sponsorship (which now translates to funding from IBM IBM Buys Red Hat: What Does This Mean for Open Source? Fedora developer Red Hat has been bought by tech giant IBM. What does this mean for the future of Linux and open source software? Read More ).

Notably, CentOS functions well on mainframes. For users that prefer a GUI, KDE and GNOME are both available. CentOS can be used as a straightforward desktop environment. Because of Red Hat support and a thriving community, CentOS remains bug free.

Who should use this: CentOS provides the functionality and stability of Red Hat Enterprise Linux. Therefore it’s perfect for advanced Linux server operating system. Use CentOS if you’re looking for a free RHEL alternative. However CentOS is fairly beginner friendly because it retains a package manager. Overall, CentOS is best as a free Red Hat Enterprise Linux alternative.

6. Arch Linux

Many servers limit power consumption. Reducing power draw is a major benefit particularly for always-on machines. Similarly, Linux server operating systems should consume few resources. Allotting resources properly is key for maximum uptime and server efficiency. Many Linux distributions use fewer resources than Windows or macOS counterparts. Arch is a simple, lightweight distribution that abides by the KISS (Keep It Simple Stupid) principle.

There’s a dedicated server section of the Arch Linux Wiki. You can learn all about configuring Arch Linux as a server operating system. While there’s not a pre-packaged server release available for download, this Wiki provides the steps to creating your own. You can install popular server software including MySQL, Apache, Samba, and PHP for Arch.

Who should use this: Arch Linux is a great all-around Linux server operating system, ideal for turning an old PC into a server. But although it’s lightweight, Arch is equally as a functional on beefy hardware. Additionally, Arch Linux is best for users with technical knowhow since you’ll have to set up Arch as a server.

7. Mageia

    For the past two years we are deploying Zentyal Linux server for our small/medium customers (from 5 users to few hundred). We mainly deploy it as a domain and directory server and file server, but depending on the customer needs we also use other modules (mail/gateway/proxy/CA...). It is an Ubuntu-based distro with nice GUI and it comes with Samba so it works well in Windows environments. It also has good documentation that helps to get started (, definitively recommend to check it out.

    I use Koozali's SME Server, based on CENTOS.
    The latest stable release is v9.2 and v10 is at Alpha 3 stage.

    The server is very stable with management through a web browser, very good documentation and many addons available to add more functionality beyond file-store, RAID 1 and 5, backup to USB, user management, firewall and email system.

    I use it initially because of its simplicity but now because of the addon backup software, AFFA, which not only does incremental backups to a user defined schedule, but can use those backups to reboot as the server being backed up if the main server fails, a process which takes about 20 minutes with my 500Gb of data. By reboot as the server, I mean, it can be reboot with the IP address, netbios name and server name of the main server and with all the user data intact and permissions correct.

    I have used AFFA to give remote support - when a user contacts me to let me know the server is dead, I can have them back online in 20 minutes or so without leaving home. I even managed to do that once from the Manly Ferry in the middle of Sydney harbour.

    For simplicity and reliability this is my favourite Linux server distro.

    "28 percent of servers are Linux"
    I don't think that's what it's stated in the linked text, which says:
    "Linux servers accounted for 28% of all server revenue"
    Quantity of machines is not the same as revenue ammount, right?

      Hahaha, well I like to ensure that Linux server beginners are aware of what they're getting into. As a Linux advocate, I encourage everyone to try it out. And truthfully, a GUI is much easier starting out. Using something like Ubuntu Server is an excellent jumping off point for server and Linux newbies. But yes, for *most* Linux server users, sans-GUI should be fine.

    What are the criteria?
    The fact that rhel isn't on here (but oracle Linux is) should be a big warning sign since much enterprise software only provides official support for rhel and suse (NOT oracle Linux).
    Btw, why do you think rhel doesn't have a "package manager"? It does. It's rpm with user friendly front ends providing by yum (though rhel 8 should be migrating to dnf).

        Not that I'm wholly supporting the idea, but in Microsoft's favor, if you ever have an issue rises to the level of an approved support incident, Microsoft will move heaven and earth to see your issue (that impacts eight people) resolved. 30 engineers working round the clock for four days? No problem.

        There's also something to be said for uniformity in management tools, but if you're in a heterogeneous environment, you probably don't have that anyway.

        Since I deal with both, I'll say that it's stuff like a certain Active Directory or .NET feature not being implemented on older systems that most often drives me nuts, or the realities of dealing with licensing costs that Linux folks MOSTLY don't have to think about. For example, I have some Windows Small Business Server machines set up for web server duties because of the way that licensing MSSQL on that OS works. They're ancient and they aren't directly exposed to the internet, but they're the biggest hassle in the world for me to manage. They'd cost a fortune to replace though, because of the number of database client access my customer would have to buy.

        Anyway, on the Linux side? Whatever. Put it in front of me. I'll deal with it. Slackware is probably more work than I care to do to get something up and running but Centos? Debian? Sure. I do sort-of reject the idea that anything *nix needs to be defined as "server" or "desktop." The only real question is whether the default install includes the stuff I'm interesting in using at the moment. On Windows there is more of a distinction, since Microsoft does artificially limit what some systems are allowed to do, but even with that, I can say that I've been in plenty of small offices where the "server" is just whichever desktop had an extra hard drive and a hard wire to a shared printer.
