  • Plesk for Linux

Question

Does Plesk support CentOS 8/RHEL 8?

What are the know limitations of Plesk on CentOS 8/RHEL 8?

Answer

Support for CentOS 8/RHEL 8 is included from Plesk Obsidian 18.0.25 release.

Currently, it has the following limitations:

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

  • Plesk was not tested on the CentOS Stream - a rolling preview release of CentOS. Therefore, it is not recommended to install Plesk on CentOS Stream.

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

  • Webalizer is not available from OS vendor repositories or EPEL for CentOS 8/RHEL 8, and thus not available for installation. Consider to use AWstats instead.

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

  • The following errors during fail2ban service start:

    CONFIG_TEXT: SELinux is preventing /usr/bin/python2.7 from write access on the directory client. For complete SELinux messages run: sealert -l ff30765b-d41a-406a-be9f-c2c863fb1dc5

  • Some third-party extensions might be incompatible with CentOS 8/RHEL 8 if they require installation of system packages. In such cases, report the problem to the extension vendor via their support channel.

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

    Hi Benjamin Hodgetts I have double-checked with CloudLinux and Centos 8 is now supported. I have updated the article.

    Hey Julian Bonpland Mignaquy. I had fixed it by myself with this article (I had maria DB installed):

    Can you please split the list of limitations into what can't be fixed and things that currently don't work?

    Hello,

    Any news on Imunify360? Or is it still in Beta?

    Also, new setup from today on Debian 10 because tests on mail issues, and "Site Import" extension fails install with the following error:

    • The execution of post-install.php has failed with the following message:

    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 Ungovernable77

    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 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.
