Obviously, upgrading the Kernel isn’t everything, but it’s certainly a critical part of it. Nevertheless, the only thing that really matters is keeping your IT environment secured. 6.09 Kernel update for CentOS 6.x templates with Hyper-V Cloud Server Pro service guide Download the Linux Integration Services from /en-gb/. One thing is for sure, the kernel version numbers are just that: numbers. “At this point,” Linus Torvalds stated, “the Kernel 5.0 is now ready!”. Linux Kernel 5.0 (Fedora 29) Linus Torvalds: “I am back!” and “the Kernel 5.0 is now ready!” This document assumes that you are familiar with yum and rpm, the software package management. Verify the upgrade of the Linux KernelĪfter the reboot, verify that the kernel upgrade succeeded using the following command: uname -a 0, for CentOS 8 server and RHEL 8, kernel upgrade is not required. For the mainline kernel: sudo dnf config-manager -set-enabled kernel-vanilla-mainlineįor the stable kernel branch: sudo dnf config-manager -set-enabled kernel-vanilla-stableĪfter the kernel upgrade, reboot. Just two lines of code, which give you peace of mind if you need to always stay “ahead of the curve”. Run this to install the latest mainline (aka pre-release) kernel: sudo dnf -enablerepo=kernel-vanilla-mainline update Running the kernel upgrade on FedoraĮither way, installing a Linux kernel upgrade on Fedora 28/29 is a no-brainer. Kernel 5.0 is now live on & Fedora 29! Download kernel repository definitionsĭownload the definitions for the Kernel vanilla repositories: curl -s | sudo tee /etc//kernel-vanilla.repo If you were to prioritize stability and insisted that it was more important to (nearly) never break anything, then kernel-vanilla-stable would be your best choice. It is suitable for a ‘high-risk’ production environment, especially when cyber security is important to your business. This is the most cutting-edge Linux kernel on Fedora. If you wanted to apply the most recent security fixes, you would be looking for the mainline branch kernel-vanilla-mainline. It can take two days or more for the mainline kernel to become the stable kernel. Step 1 - Find current kernel version Use the uname command to display the current version of kernel the system is running.: uname -sr Output: rootvps uname -sr Linux Step 2 - Enable ELRepo Import the public key and install the ELRepo RPM package using the below command. Many critical cyber security fixes make it at first only into the mainline release. To update all packages for the version that is currently installed, without updating kernel to latest release, create a file in /etc// called CentOS. When upgrading your Linux kernel, you are faced with a choice between the mainline and stable branches. Next, install the dnf-plugin-system-upgrade package: $ sudo dnf install dnf-plugin-system-upgrade Mainline vs. Update your system: $ sudo dnf upgrade -refresh You don’t need to concern yourself with the configuration of the grub boot manager, which is a frequent source of trouble on CentOS and RHEL. On Fedora, all it takes is a time-saving two-liner. In CentOS 6.x/7.x and RHEL 6x./7.x, upgrading the Linux Kernel is a painful procedure which requires about a dozen steps. Now update /etc/nf and make sure the new kernel 4.x is selected as default kernel and just reboot your VPS/Dedicated Server to use the new kernel.As zero-day exploits become increasingly common, keeping the kernel up to date is a top priority. Yum -enablerepo=elrepo-kernel install kernel-ml Kernel 4.x is highly optimised and gives a lot of boost in performance to all Linux servers, here are few simple commands to upgrade your Kernel to 4.x on your CentOS 6 / CentOS 7 / RHEL 7 VPS (It will work with any KVM Based VPS like the ones provided by ) or Dedicated server : Upgrade to Kernel 4.x in CentOS 6 or CentOS 7
