I have been using CENTOS 7 successfully for a while, but now I have a problem. Need to update the kernel to 4.14.87. Found a tar of that kernel release and tried to install, but just came up with problem after problem, because of the need to update other parts of the OS before I could move forward with the kernel update. Failed at this point, so searched for a later release of CENTOS 7. I believe CENTOS 7.7 is what I need. Found CentOS-7-x86_64-Everything-1908.ISO, which was 10GB file, so downloaded and burned to Blu Ray disc. Too big for DVD. This was successful, but when I tried to install to a new sata disk it went through all the usual processes, but just ended up with a prompt, showing a very old kernel version 3.10.

Anyone got any ideas of how to move forward on getting and installing CENTOS 7.7 with much more up-to-date compilers etc., so that I can install the required kernel release ?

Normally, a yum update should be sufficient to go to the latest version of Centos 7. It's not clear to me what you did with the everything-ISO; I hope your system is still OK.

3.10 is the kernel version for all Centos 7 releases. To go to a version 4 kernel, you need to install Centos 8 (based on kernel 4.18 if I am not wrong) or use a different distro.

The currently installed Centos version can be found in /etc/centos-release.

They could install the latest kernel (kernel 4.x or 5.x) from elrepo, they just need to add the elrepo repo to yum's repolist.

Best question I have is WHY you 'need' to update the kernel, past what comes with the distro and standard repos. What are you needing the new kernel for? What's it going to do that the stock kernel doesn't?

All CentOS 7 releases (and the RHEL ones they are based on) will be with a 3.10 kernel with BACKported security patches (so it is NOT a stock 3.10 kernel).
To update the system you will have to upgrade to either CentOS 8 or CentOS Stream (which currently is still almost identical to 8, but is a "continous" release, so will get updated packages etc without any versioned new release).
See for the install images on centos.org

Running CentOS Linux 7.7.1908 -- Current kernel is Linux 3.10.0-1062.4.1.el7.x86_64 on x86_64

Yes, you should probably update to 7.7.x No, that won't get you the 4.14.87 kernel.

Repeating the question: Why do you want to use a newer kernel?

Thanks for the replies. I have not tried to update my master CENTOS 7 disk. I had a copy and tried to install the 4.14.87 kernel and that is where everything went wrong. So I located the CentOS-7-x86_64-Everything-1908.ISO, believing that it was a version that would be more up to date. Used a new disk, just as a precaution, so nothing lost when it failed to install and load correctly. I need to update to the 4.14.87 kernel because I have compatibility issues with releasing a driver. It must have same kernel release as end user system or it won't work. I will try to locate a CENTOS 8 release and start again. Forgive me for asking, but where is best site to download CENTOS 8 ?? I prefer to leave my master CENTOS 7 disk installation alone and start from scratch with a new installation, just as a precaution.

Um. centos.org
