How to Purchase a KernelCare License
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.
You can only install KernelCare on systems that run one of the following operating systems:
CentOS 6 and 7.
Red Hat® Enterprise Linux® (RHEL) 6 and 7.
CloudLinux™ 6 and 7.

If the KernelCare Security alert does not appear in the list of security alerts, one of the following conditions exists on your server:

When you purchase a KernelCare license through the WHM interface, the system automatically selects the appropriate license type for your server and detects the IPv4 address to license. Currently, you can only purchase monthly licenses through the WHM interface. Verify your license order, accept the legal agreements, enter or select the desired payment information, and then click Pay Now.
After the cPanel Store successfully processes your order, a confirmation message will appear, and you will receive an invoice email from the cPanel Store. After you successfully purchase a license, the KernelCare License banner will no longer display in the WHM interface.
If the cPanel Store experiences problems with your order, an error message will appear, and you may receive emails from cPanel Customer Service to help you resolve the issue.
Your server will automatically download and install KernelCare. To verify this, navigate to WHM’s Security Advisor interface (WHM >> Home >> Security Center >> Security Advisor) again and the KernelCare notice will confirm that the installation succeeded.
