Upgrading UEK Kernel on Oracle Linux 7

In general I work almost exclusively on Macs these days. However, for work and various other reasons I always tend to have a VM with Linux on my Mac to test, run, script things. My VM runs Oracle Linux (OL) on VirtualBox. Oracle Linux just makes a lot of sense for me as we run everything on Oracle Linux internally and in general it is a solid Linux distribution. Of course, once in a while I have to update my Linux version as well to make sure that my Linux environment remains on the latest and greatest. Right now is such a time again as Oracle Linux 7 Unbreakable Enterprise Kernel 5 just released. In the past I was always a bit scared about upgrading kernels because I had little clue of what I was doing.  Turns out that it is a lot easier than one might think, and here is how you do it:

tl;dr

1. Download new repo list: wget http://yum.oracle.com/public-yum-ol7.repo
2. Enable the new repo: yum-config-manager --enable ol7_UEKR5
3. Upgrade the environment: yum upgrade
4. Reboot the environment: reboot

Download the New Repo List

What I would like to outline in this post is how to upgrade the Unbreakable Enterprise Kernel, short UEK. The steps are actually fairly simple. You will need to have access to the root user as this upgrade can only be performed by root.

As a first step it’s always good to check what you already have. So let’s see what the current repository list for yum looks like by heading over to a terminal as root and type yum repolist:

[root@localhost ~]# yum repolist
Loaded plugins: langpacks, ulninfo
repo id repo name status
ol7_UEKR4/x86_64 Latest Unbreakable Enterprise Kernel Release 4 for Oracle Linux 7Server (x86_64) 704
ol7_addons/x86_64 Oracle Linux 7Server Add ons (x86_64) 273
ol7_latest/x86_64 Oracle Linux 7Server Latest (x86_64) 26,884
repolist: 27,861

In my example I have three repositories configured:

1. The ol7_UEKR4 repository for UEK4 updates
2. The ol7_addons repository for various addons such as Docker Engine.
3. The ol7_latest repository for the latest releases of OL7 core packages

To be able to upgrade to UEK 5, the new version, I have to enable that repository (ol7_UEKR5) for yum so that it can see the new packages, download them and perform the upgrade. Luckily, Oracle always keeps an up to date yum repositories file available on the web at http://yum.oracle.com/public-yum-ol7.repo which contains the latest repositories information. All I have to do is to download it into the right directory where yum expects it, which is /etc/yum.repos.d/:

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# wget http://yum.oracle.com/public-yum-ol7.repo
--2018-07-02 17:44:13-- http://yum.oracle.com/public-yum-ol7.repo

Note that wget doesn’t overwrite the original but saves the new version with an .1 at the end. You will have to manually overwrite the old file. Then it’s time to enable the new repository and disable the old one:

When issuing yum repolist another time you should now see the ol7_UEKR5 repository instead of the ol7_UEKR4 one:

[root@localhost yum.repos.d]# yum repolist

repolist: 26,967

Note that also the ol7_addons repository has disappeared as it is not enabled by default. I can easily enable it again via yum-config-manager --enable ol7_addons.

Upgrade the Environment

The next step is to upgrade the environment. This will install the new version of UEK as well as a lot of packages that have new versions for the new kernel. At this point I should point out that you should not light heartedly type the next following commands as it will perform a full on Linux kernel upgrade. yum actually allows you to decide between updating to the latest packages and deleting the old ones, i.e. upgrade, or to update to the latest packages and keep the old ones, i.e. update. As I don’t have any needs for the old packages I usually choose yum upgrade, here we go:

[root@localhost yum.repos.d]# yum upgrade
Loaded plugins: langpacks, ulninfo
ol7_UEKR5 | 1.2 kB 00:00:00
ol7_addons | 1.2 kB 00:00:00

Complete!

After yum completed the upgrade you can verify once more that the upgrade of UEK was successful via yum list installed kernel-uek:

[root@localhost yum.repos.d]# yum list installed kernel-uek
Loaded plugins: langpacks, ulninfo
Installed Packages
kernel-uek.x86_64 4.1.12-94.3.8.el7uek @ol7_UEKR4
kernel-uek.x86_64 4.14.35-1818.0.9.el7uek @ol7_UEKR5

The output shows me that the new kernel-uek version from the ol7_UEKR5 repository has been successfully installed.

Reboot the Environment

Last but not least it’s time for a reboot to boot the OS with the new kernel. This can be easily done via the reboot command:

[root@localhost yum.repos.d]# reboot
Connection to localhost closed by remote host.
Connection to localhost closed.

After the reboot you can verify that the OS is running the latest kernel via the uname -r command. You should see that the version matches with the version that the yum list installed kernel-uek command showed you for the ol7_UEKR5 installed kernel:

[root@localhost ~]# uname -r
4.14.35-1818.0.9.el7uek.x86_64

Bonus Task: Uninstall the Old Kernel(s)

After everything is up to date and rebooted you are good to go. However, you may want to remove the old kernel which yum couldn’t remove as the OS was running it while upgrading itself. You don’t have to do this but if you would like to keep your environment clean it’s a good thing to do. By typing yum list kernel* I can quickly see which kernels are still installed:

[root@localhost ~]# yum list installed kernel*
Loaded plugins: langpacks, ulninfo

kernel-uek-firmware.noarch 4.1.12-94.3.8.el7uek @ol7_UEKR4

The above output shows me that I have three different kernel versions installed:

1. kernel.x86_64 3.10.0-862.6.3.el7 from the @ol7_latest repository
2. kernel-uek.x86_64 4.1.12-94.3.8.el7uek from the @ol7_UEKR4 repository
3. kernel-uek.x86_64 4.14.35-1818.0.9.el7uek from the @ol7_UEKR5 repository

I actually don’t need the kernel.x86_64 nor the kernel-uek.x86_64 4.1.12-94.3.8.el7uek versions and can just delete them. Fortunately, yum will skip the currently running kernel, so I can just do a yum remove kernel* kernel-uek*:

[root@localhost ~]# yum remove kernel* kernel-uek*
