CentOS Project Announces Early End-of-Life Date for CentOS 8

We recently found out that the CentOS Project accelerated the End-of-Life date for CentOS 8, meaning that no further operating system updates will be available after December 31, 2021.

In the meantime, even though Plesk will continue supporting both CentOS 7 and 8 and CloudLinux 7 and 8 until their planned end-of-life dates, the Plesk team strongly recommends switching to AlmaLinux OS, supported since Plesk Obsidian 18.0.35.

CentOS also announced other critical changes to its roadmap that have an impact on the Plesk products and our users and partners:

  • CentOS 8 will be transformed to an upstream (development) branch of Red Hat Enterprise Linux called CentOS Stream, where previous CentOS versions are part of the stable branch.
  • Although CentOS 7 life cycle remains unchanged, updates and security patches will be available until June 30, 2024. The life cycle timing is subject to change.

For additional information on the CentOS Project changes, you can also read their detailed blog post or refer to the CentOS FAQ page.

Plesk Support for CentOS 8

Plesk Support for CentOS 8 - CentOS 8 Announces Early End-of-Life Date - Plesk

If you’re wondering how CentOS 8 End-of-Life policy could affect your Plesk, here are some workarounds that you may want to hear. The good news is that Plesk has already been investing in product support for Ubuntu for decades, and will continue to support CentOS 8. 

Plesk Obsidian supports Ubuntu 20.04 LTS starting from Plesk Obsidian 18.0.29, and Plesk Onyx 17.8, Ubuntu 18.04 LTS. Nonetheless, if you’re a Plesk Onyx user, note that from April 22, 2021, it will no longer be available for new purchases and will stop receiving further development and technical support requests. Please read this article to learn how to upgrade to the latest Plesk Obsidian and how to automate renewals to keep your Plesk updated at all times.

When to Transition and Other Alternatives

CentOS 7 still remains a good choice for new servers, and it is the most popular choice amongst Plesk users. That’s why, it will be officially supported by RHEL (and also Plesk) until June 30, 2024.

As an alternative to CentOS 8, though, the Plesk team strongly recommends switching to AlmaLinux OS, supported starting from Plesk Obsidian 18.0.35. In this case, in-place conversion of CentOS 8 to AlmaLinux is as easy as running a script from the AlmaLinux team. Please refer to this page for more information.

AlmaLinux OS is a free new RHEL fork from the CloudLinux team, and it’s been developed in close cooperation with the community.

Additionally, we’ll also consider supporting CentOS Stream based on actual industry flow. So, people who will make a decision to follow the official RHEL distro will have CentOS Stream as an option. RHEL states that switching from CentOS 8 to CentOS Stream will be in place and smooth. 

Plesk will also keep supporting CloudLinux OS 8. This additional supported operating system provides an upgrade path for customers with CloudLinux 6 or 7 deployments. CloudLinux is another commercially supported operating system that many of our partners benefit from. CloudLinux includes many advanced features such as improved user resource limitations, increased user visibility, and advanced customer isolation.

  1. Please note the official RedHat Enterprise Linux 8 is now available for free for individuals and small organisations (up to 16 servers): https://access.redhat.com/discussions/5719451

  2. Will you support RHEL forks that keep 1:1 mirroring such as the new AlamaLinux?

      Hi Brad, yes, as explained in the blog post, we also plan to deliver AlmaLinux OS support for Plesk in summer 2021. Thank you!

  3. I’m running CentOS 8 and it clearly seems that I will need to migrate to a new system. Since I see no mention of supporting in place upgrading to AlamaLinux. What OS would you recommend at this point that is also supported by majority of extensions?

      Hi Abel, please refer to this page for all operating systems which are receiving updates and support from the OS vendor and are therefore supported by a current and supported version of Plesk. Thanks!
