CentOS 8/RHEL 8 support in Plesk

  • Plesk for Linux

Question

Does Plesk support CentOS 8/RHEL 8?

Answer

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

Known limitations:

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

      • Plesk has not been tested on CentOS Stream. Therefore, it is not recommended to install Plesk on CentOS Stream.

      • 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 CentOS 8/RHEL 8. In such cases, report the installation issues to the extension vendor via their support channel.

      • PHP 7.0 and earlier PHP versions are not available for installation, because CentOS 8 system libraries are not compatible with them.

      • Webalizer web-statistics feature is not available for installation as its packages are absent in the OS repository for CentOS 8/RHEL 8, moreover, Centos 8 is going to be EOL at the end of 2021. Consider using AWstats instead. There are plans to add Webalizer support during Q1 2022 for Almalinux OS which is the easy in-place conversion from CentOS 8.

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

Workaround for Webalizer installation on Centos 8 OS
  1. Log into the server via SSH.
  2. Enable the EPEL repository with the command:

    # yum install epel-release

  3. Run the command below to install the Webalizer package:

    # dnf install webalizer

  4. Execute the following command to refresh installed server components:

    # plesk sbin packagemng -sdf

    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 Jonathan

    This wasn't tested but should work. Use this instruction to register custom PHP version in Plesk: https://support.plesk.com/hc/en-us/articles/115000497853

    Let me note that enabled custom repositories sometimes prevent Plesk form installing updates.

    Hello Peter

    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).

    Hello Bryan Joshua Pedini

    Imunify360 supports CentOS 8 starting from version 4.9, which is currently in beta.

    As far as I know, the "Site Import" issue was investigated in a ticket.

    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.

    It seems like there are now Docker packages available for CentOS 8?

    Hello Mitchell van Bijleveld it seems like yes, thank you for brining our attention to this! We will do research on this to see if we can add support for Docker on CentOS 8.

    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.

    Klinging on what Steve Yates wrote above: CentOS Linux will be retired and support end of 2021. Are there any plans to support CentOS Stream instead of the "normal" releases of CentOS 8 so have a proper subsitute?

    Specifically CentOS 8 will be retired at that point, CentOS 7 will still be supported until June 30th, 2024.

    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

    I just performed the following tests with:

    1 - OS: CentOS Stream 8
    Product Plesk Obsidian Version 18.0.32 Update # 2, last updated on Jan 14.

    2 - OS CentOS Linux 8.3.2011
    Product Plesk Obsidian Version 18.0.32 Update # 2, last updated on Jan 17, 2021

    ** Migration tool: Plesk Migrator Version 2.20.2-962

    **** - Server to be migrated:
    * OS CentOS 6.10 (Final)
    Product Plesk Obsidian Version 18.0.31 Update # 3, last updated 12/25/2020

    Result:

    Both CentOS 8 (Stream and Linux 8.3) worked correctly. Much faster Stream version, but ....

    * Grafanna does not respond with Stream version.
    * Plesk Migrator does not
    * PHP versions 5.6 and earlier did not respond.
    * Wersites with summer prior to PHP 7.1 do not respond with ioncube_loader.

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