Overview

This document describes how to install the KernelCare software. KernelCare automatically updates your system's Linux kernel without the need for a reboot.

Important:

You must run these commands as the root user.


Install KernelCare

Check for compatible kernels.

Before you purchase and install KernelCare, make certain that your system possesses a compatible kernel. To do this, read the the KernelCare documentation.




Choose and run your preferred command.

You can choose between two different SSH commands to begin the KernelCare installation process. To begin the KernelCare installation process, run one of the following commands:

curl -s https://repo.cloudlinux.com/kernelcare/kernelcare_install.sh | bash
wget -qq -O – https://repo.cloudlinux.com/kernelcare/kernelcare_install.sh | bash




Register the license key.

The KernelCare license key deploys and registers your server. To register your key, run the following command:

kcarectl –register $kc_key




Check for applied patches.

After you register KernelCare, you will need to check for applied patches. This ensures that the automated kernel security updates ran properly on your server. To check for applied patches, run the following command:

/usr/bin/kcarectl –info





Manually check for patch updates.

KernelCare will automatically check for new patches every four hours. If you want to check for new patches yourself, run the following command:

/usr/bin/kcarectl –update
