CentOS vs. Debian: Overview

CentOS and Debian are Linux distributions that spawn from opposite ends of the candle.

CentOS is a free downstream rebuild of the commercial Red Hat Enterprise Linux distribution where, in contrast, Debian is the free upstream distribution that is the base for other distributions, including the Ubuntu Linux distribution.

As with many Linux distributions, CentOS and Debian are generally more alike than different; it isn’t until we dig a little deeper that we find where they branch.

CentOS vs. Debian: Architecture

The available supported architectures can be the determining factor as to whether a distro is a viable option or not. Debian and CentOS are both very popular for x86_64/AMD64, but what other archs are supported by each?

Both Debian and CentOS support AArch64/ARM64, armhf/armhfp , i386 , ppc64el/ppc64le. (Note: armhf/armhfp and i386 are supported in CentOS 7 only.)

CentOS 7 additionally supports POWER9 while Debian and CentOS 8 do not. CentOS 7 focuses on the x86_64/AMD64 architecture with the other archs released through the AltArch SIG (Alternate Architecture Special Interest Group) with CentOS 8 supporting x86_64/AMD64, AArch64 and ppc64le equally.

Debian supports MIPSel, MIPS64el and s390x while CentOS does not. Much like CentOS 8, Debian does not favor one arch over another —all supported architectures are supported equally.

CentOS vs. Debian: Package Management

Most Linux distributions have some form of package manager nowadays, with some more complex and feature-rich than others.

CentOS uses the RPM package format and YUM/DNF as the package manager.

Debian uses the DEB package format and dpkg/APT as the package manager.

Both offer full-feature package management with network-based repository support, dependency checking and resolution, etc.. If you’re familiar with one but not the other, you may have a little trouble switching over, but they’re not overwhelmingly different. They both have similar features, just available through a different interface.

CentOS vs. Debian: Filesystems

Is the default filesystem a consideration for you? If so, XFS fans can rejoice that it is the CentOS default. Those who are more of the EXT4 persuasion may prefer Debian. Both XFS and EXT4 are popular and well-supported options for CentOS and Debian, so the default filesystem is likely not a determining factor. Besides, both distros support numerous other filesystems, such as ext2/3, NFSv3/4, btrfs, SMB, GFS2 and many more. (Note: btrfs is supported by CentOS 7 only.)

CentOS does not officially support some of the filesystems that Debian offers. Most notably is ZFS. Debian provides ZFS support through a DKMS contribution, but ZFS is not supported on CentOS at all (although ZFS support is available through 3rd parties).

CentOS vs. Debian: Kernel

Need the latest/greatest Linux kernel in your environment to support the newest hardware or kernel features? In that case, you may find Debian’s 4.19 kernel appealing.

CentOS does have kernel-lt-5.4 and kernel-ml-5.10 packages available through 3rd party repos, but CentOS ships with kernel 3.10 (CentOS 7) or 4.18 (CentOS 8).

Both Debian and Red Hat backport security fixes from newer kernels to their current kernels, though, so falling behind with regards to security isn’t usually a concern.

CentOS vs. Debian: Upgrading

One feature that gives Debian an advantage is that of major version upgrades. CentOS supports minor version upgrades, such as CentOS 7.8 to CentOS 7.9, but does not support (or only weakly supports) major version upgrades, such as from CentOS 6 to CentOS 7 or CentOS 8. CentOS major releases typically have a 10-year lifespan, but in-place upgrades can leave a system in limbo, somewhere between one major release and another, so we don’t typically recommend them. (Note: We recommend offline/parallel build upgrades between CentOS major releases.)

Debian’s ability to upgrade from one stable release to another, such as from Debian 9 Stretch (stable) to Debian 10 Buster (stable), can help keep a system up to date after many years. Debian typically releases a new major version on a 2-year release cycle with 3 years of full support and an additional 2 years of LTS (Long Term Support) for a 5-year lifespan, so being able to upgrade to the next stable major release is handy.

Major version upgrades aren’t of much use to those who deploy systems in a more ephemeral manner as it is often relatively easy to update the base images to a newer version, but for those who deploy systems that are expected to have a multi-year lifespan, major version upgrades can pose a significant level of effort.

CentOS vs. Debian: Support

CentOS is largely community supported, but Red Hat does accept bug reports submitted by end users for CentOS and the upstream RHEL release. CentOS commercial support is not provided directly from the CentOS Project (or Red Hat), but is available through 3rd parties, such as OpenLogic.

Debian is primarily community supported, including offering a bug tracker. Debian does offer a list of consultants that can be hired to help resolve issues, but those consultants operate independently.

Some downstream distributions based on Debian have commercial support options, with Ubuntu probably being the most prolific.

Final Thoughts

In the end, choosing the distribution that is best for you comes down to technical requirements, internal resources, support options and business decisions.

If you must run on a RHEL-compatible distribution for application reasons, CentOS is the winner. If your engineering team’s experience is with distributions that use DEB packages, Debian would be a wise choice.

If you can support your systems entirely via your internal talent pool, both CentOS and Debian could be options. But, if you’d like to shore up your options and have commercial support available, maybe the commercial CentOS support options would sway you.

CentOS vs Debian | Detailed Comparison

CentOS vs Debian Detailed Comparison

When it comes to choosing a Linux-based operating system for your server or desktop, the options can be overwhelming. CentOS and Debian rank among the most widely used choices available. Both are open-source, stable, and reliable, but they differ in many aspects. Not sure about the differences? Well, right here, we will delve deep into the world of CentOS vs Debian with a detailed comparison of their unique features, security, stability, and more.

CentOS vs Debian

CentOS is a community-driven project that is derived from the Red Hat Enterprise Linux (RHEL) source code, while Debian is a non-commercial project that is developed by a team of volunteers. Both are widely used by individuals, small businesses, and large enterprises. But if you know the differences, you can make a better choice of which OS is better suited for your needs. So let’s get into the comparison of the two.

1: User Interface and ease of use

CentOS does not come with a default graphical user interface (GUI). Rather, it employs a command-line interface (CLI), which might pose a challenge for novice users. However, CentOS can be installed with various GUIs, such as GNOME and KDE, which make it easier to use.

Debian comes with a default GUI, which makes it more user-friendly than CentOS. The default GUI is based on the Xfce desktop environment, known for its efficient and swift performance. Debian also offers a variety of other desktop environments, such as GNOME, KDE, and LXDE, which users can choose from.

2: Package management

Package management is a crucial aspect of any operating system as it determines how software packages are installed, updated, and managed on the system. CentOS and Debian have different package management systems.

YUM (Yellowdog Updater, Modified) is the package manager utilized by CentOS, enabling users to efficiently install, update, and manage software packages through command-line functionality. YUM offers access to a substantial repository of packages and is commonly employed by system administrators.

Debian, on the other hand, uses the Advanced Packaging Tool (APT) package manager, which is also a command-line tool that allows users to install, update, and manage software packages on the system. APT has a vast repository of packages and is widely used in Debian-based systems.

3: Security

Safety is a paramount consideration for all operating systems, and both CentOS and Debian place a strong emphasis on ensuring security.

CentOS provides security updates and patches via the YUM package manager. CentOS also includes SELinux (Security-Enhanced Linux), a security module that provides mandatory access control policies to enhance the security of the system.

Debian also provides security updates and patches via the APT package manager. Debian also includes AppArmor, a security module that provides mandatory access control policies similar to SELinux.

4: Release Model

CentOS follows a stable release model, which means that new versions are released every few years, and each version is supported for a long period of time. CentOS is a favored option for servers that need extended maintenance and consistency, leading to its popularity.

Debian follows a rolling release model, which means that new versions are released continuously, and users can upgrade to the latest version at any time. Debian becomes a favored choice for those seeking the most recent features and security enhancements.

5: Stability and Reliability

CentOS and Debian are both recognized for their dependability and steadiness, rendering them appropriate for production settings.

CentOS derives from the source code of RHEL, recognized for its dependability and durability. CentOS provides long-term support and maintenance for each release, ensuring that the system remains stable and secure.

Debian is also reputed for its stability and unwavering performance. The rolling release model ensures that users have access to the latest security updates and bug fixes, while the testing and unstable branches provide a way to test new features before they are released.

6: Use Cases

CentOS and Debian are suitable for use in a wide range of settings, including web servers, application servers, and database servers.

CentOS is often used in enterprise environments where stability, security, and long-term support are important. It is also popular for web hosting due to its support for the Apache web server.
