Question

Does Plesk support RHEL 8?

Answer

Support for RHEL 8 is available starting from Plesk Obsidian 18.0.25.

Known limitations:

      • No live/in-place upgrade from CentOS/RHEL 7 to RHEL8 available. Plesk R&D team is researching this feature to support it in future Plesk releases.

      • Legacy components mod_bw, mod_perl and mod_python are not available for installation. These components are deprecated.

      • Currently, the following ModSecurity rulesets are available for selection: OWASP, Comodo.

      • Some third-party Plesk extensions might be incompatible with RHEL 8. In such cases, report the installation issues to the extension vendor via their support channel.

      • Webalizer web-statistics feature is not available for installation as its packages are absent in the OS repository for RHEL 8. Consider using AWstats instead.

        Note: as a workaround, the Webalizer package can be installed from the EPEL repository at your own risk.

    Hello Mitchell van Bijleveld

    Yes, it's going to be available. Work on it is currently in progress.

    I performed a migration from an old server with Centos 7 to Centos 8 today. Some options related to mod_bw are still displayed in the service settings.
    Is this a bug? Is there a way to remove them?

    Only the remote docker functionality. Docker managing on the server is still not available.

    Atomic have not yet released their ModSecurity rules compatible with CentOS 8/RHEL 8, since it is not available for selection at Tools & Settings > Web Application Firewall > Settings. Therefore, the following ModSecurity rulesets are available: OWASP and Comodo

    Just checked the AUM script - it appears that CentOS 8 is now supported :-)

    Hello Peter Olsen

    I confirm this was also reproduced on our test server.

    Currently, it's planned to make corresponding updates in Plesk in 18.0.31 (may be changed in case f high priority bugs found).

    Hi Sebastian Ayala,

    This happens because, on CentOS 8, your Plesk installation has mod_bw. It's expected, and if you don't want it the only way is to remove such component.

    Hi My Domain Labs,

    There may be different reasons why permissions change on website files, for example, if it is a WordPress website, some plugins are known to cause this behavior, or a malicious script if the server was hacked. I recommend opening a support ticket with us so we may investigate this further on the server.

    Hi Peter, the ball is on Atomicorp side. As soon as they add support for RHEL/CENTOS 8 we will be able to use it in Plesk. To clarify ETA you may want to reach them here. Meanwhile I do recommend to use Comodo.

    Hi Francisco Roman Garcia Rodriguez,

     

    thanks for your support: Would Docker be supported with CentOS 8 in next release? Could I safely install Docker on the same server of Plesk?

    I will create a UserVoice!

    @Karl May,

    According to Atomicorp support, RHEL 8 is already supported and they have plans to add CentOS 8 support later this year.

    Thank you for bringing this to our attention, stay tuned for the changes in this article.

    Does the latest Plesk Obsidian Version 18.0.33 allow Centos 8 to run docker local on the same server?

    I'd say something needs to happen soon because my Plesk panel had been popping all kind of errors and I'm pretty sure it has been due to this... it seems like every time I run a Plesk repair all on my system I have to run a Plesk repair fs verbose immediately after because I have files that it doesn't like.

    I would like to use CentOS 8 soon, so I check this article regularly. I am mainly interested in whether Atomic now supports ModSecurity. If you update the page, which contains a list of problems, it would be nice to know if you have removed or added items. I can only see that a change has been made to the article, but not what exactly.

    Is there any news about Atomicorp and Modescurity yet? I would like to rent a new CentOS 8.2 server and use "Atomic Advanced" there.

    Hi Francesco Zanti,

    It's the first time I hear about Podman, and I'm not aware of anything regarding this in Plesk.

    I encourage you to create a UserVoice request.

    Hello,

    because of CentOS 8 EOL at December 2021, Plesk should support upcoming CloudLinux 8 Free Edition, because it is already supports the classic version of CloudLinux 8. More at https://blog.cloudlinux.com/announcing-open-sourced-community-driven-rhel-fork-by-cloudlinux
