it is complicated work so i suggest hire skilled administrator to do that or your server may be unbootable.
last time i asked PSM to upgrade kernel for my server and i needed to contact DC twice for reboot :dVN-SG Hosting | Shared Hosting | Reseller at very affordable price |

It's not difficult to explain how to compile a kernel.
The problems will arise in there being numerous kernel options that you probably wont know how to answer wether you want the driver/support compiled in, not compiled in, or as a module if possible.
In a bad attempt, you may compile and install a kernel that is missing support for something important. Say, you forget to compile in the correct network ethernet nic driver... your machine will boot up and be running just peachy... you just wont beable to connect to it through the network. Thus, having some sort of remote serial console ability, or a quick ability to have someone in a datacenter console into the machine and select a different kernel to boot will be important if this is a production machine.
Worst case, it will be missing something important and will kernel panic on boot up.
It would also help to know several specifics:
What OS?
What Distribution?
What is the current kernel you are running?
What control panel software you are using if any?
Why do you think you need to, or want to upgrade your kernel to the latest stable version?
What problems are you having with the current kernel?
Many further questions will probably come up based on the answers to those questions...

Have you ask your server provider? If it is unmanaged, get a third party person / server management company to handle it.

If you are using Redhat varient (Like fedora, ubuntu, centos, redhat etc) then you can just use the following command to update your kernel:

This message shown on WHM when I logged in today:
There are several known Linux kernel exploits which may allow local privilege escalation. These exploits have become commonplace in recent weeks and can be avoided by ensuring that your kernel is updated to the latest available version. While cPanel will help ensure your system services and software are up to date, kernel updates are outside the scope of cPanel. Kernels with known vulnerabilities include, but are not limited to, 2.6.9-22 and 2.6.9-34. Please check your running kernel for updates periodically. This will help ensure the overall integrity of your server and data.
does this affect Kernel 2.4.29-am02 #1 SMP ?

Is that an allmanaged server ? You should put in a request to get the Kernel upgraded in that case. That isn't involved in the same kernel exploits, but it's not the latest version.

how did you know that's an allmanaged server? well, I'm afraid upgrading might break things. some have said not to while some say to use the latest. I really don't know what to do...

And after this update no problem should occur, as it only updates some specifications under kernel.

We've had a fleet of them in the past. We still have a few. For your needs, I would SERIOUSLY recommend, you put in a request to the helpdesk to upgrade the Kernel to the latest 2.4x series. If you're not sure what you're doing, you're likely to void the agreement with AM. So put in the request, and they will do that for you.
AM hasn't ever agreed to do our servers with 2.6x kernels - so you prolly can't ask for that series of Kernel - though the performance on this is actually a little faster - I think .

ok, I will put in a request tomorrow at a less busy time. how long should the kernel upgrade take? I wonder why AM won't do 2.6x kernels. Thanks.
