Hello,

I have linux i686 and I want to upgrade kernel from 2.4.21-40.EL to the last version.

how ? and from where ?

for more information :

PHP : 4.4.2
Mysql : 4.1.19-standard
Apache : 1.3.36 (Unix)


Thanks.

For the kernel sources follow this link: ftp://ftp.kernel.org/pub/linux/kernel

For the instructions on how to compile follow this one: http://www.mjmwired.net/resources/mjm-notes-fc2.html

But there might be some changes in the steps for compilation and installation depending on the flavor of linux you are using.

Also be advised that there were major changes going from 2.4 to the 2,6 kernel series. In particular, make sure thar rhw modutils/module-init-tools you have support a 2.6 kernel.If not you'll need to get the latest version and install it before you upgrade your kernel.

Is there some particular reason you want to do this? By the looks of your kernel version, you're running RHEL 3 or a rebuild thereof. You might consider upgrading to version 4, which uses a 2.6 kernel. The Red Hat enterprise kernels are built and configured with stability in mind, not necessarily to be the latest and greatest. If you're running a production Web server, which it sounds like you are, this is a good thing.

does anyone know where i can find the document which is about upgrading kernel 2.4 to 2.6? i remenber that was in the Documentation of kernel package,but i cann't find it ,anyone know where it is? thx!!!

I would recommend that you install the (say, Red Hat, if that's what you're using now...) distro that uses [any...] 2.6 kernel first. Then you can upgrade to a later 2.6 kernel as you wish.

There are a lot of fundamental changes between 2.4 and 2.6 that are tricky to accomplish, and fairly irreversible. (I say that from actual experience. ) It can be done, and I've done it, and frankly I wouldn't do it again. Let the distro upgrade process get you over that hurdle "automagically," then go from there.
