Overview
KernelCare automatically updates your system’s Linux® kernel without the need for a reboot. cPanel & WHM servers allow you to purchase a license for KernelCare from WHM’s Security Advisor interface (WHM >> Home >> Security Center >> Security Advisor).
- Before you purchase and install KernelCare, make certain that your system possesses a compatible kernel. To do this, read the KernelCare documentation.
- To install and run KernelCare, you must disable Secure Boot if you enabled Secure Boot previously.
- You can only install KernelCare on systems that run one of the following operating systems:
- CentOS 6, 7 and 8.
- Red Hat® Enterprise Linux® (RHEL) 6 and 7.
- CloudLinux™ 6, 7 and 8.
- AlmaLinux 8.
For the latest information about the operating systems that cPanel, L.L.C. supports, read our Installation Guide documentation.
Hosting providers can configure whether this option sends the purchaser to the provider’s custom URL, an email address, or the cPanel Store. They can also disable the banner for their licensed servers from Manage2’s Update Company Information interface (Manage2 >> Company >> Update Company Information).
