Frequently asked questions

How can I test-drive KernelCare?

You can try KernelCare absolutely free for 30 days on an unlimited number of servers. After the trial period is over, you can purchase licenses through CloudLinux Network (CLN) by logging in to cln.cloudlinux.com.

Can I use a single KernelCare key to register multiple servers?

What happens if I install KernelCare but my kernel is not supported?

If your kernel is not supported, KernelCare will detect it and will do nothing. There is no danger (but also no benefit) of running KernelCare on unsupported kernels. KernelCare will provide a message “Unsupported Kernel” when it doesn’t know anything about a particular kernel. See the list of supported kernels
