Non-panel and custom panel limitations

1. In the non-panel environment, for now, we can guarantee all of the following CloudLinux Shared components functionality:

LVE limits
LVE Stats
MySQL Governor
CageFS
PHP Selector
HardenedPHP
Apache mod_lsapi PRO

2. Due to integration restrictions with some panels, we are unable to retrieve panel-related information (e.g. a list of domains or handlers used). As a result, we are currently unable to provide the following components:

PHP X-Ray
Slow Site Analyzer
Website Monitoring Tool
Ruby selector
Centralized Monitoring

3. CloudLinux OS Solo/Admin editions are restricted to one and five users respectively on the UI level and might not work as expected.
4. For the custom panel installations, once integration with the CloudLinux components is set, the following components will work in the CloudLinux OS 9 environment:

LVE limits
LVE Stats
MySQL Governor
CageFS
PHP Selector
HardenedPHP
Python Selector
NodeJS Selector
Apache mod_lsapi PRO
PHP X-Ray
Slow Site Analyzer
Reseller limits

Full support for all control panels ETA

We’re working now to make CloudLinux OS 9 available in other popular control panels: cPanel, Plesk, and DirectAdmin. We expect to introduce the full support of the CloudLinux OS 9 editions – Shared/PRO/Admin/Solo in the year 2023.

How to install

Please note that current release is still in Beta! You can install CloudLinux OS 9 on a new server from the ISO image or convert the existing AlmaLinux 9 server to the CloudLinux 9. Please refer to the documentation for details.
