I thought all the distributions could build kernel in the same way, obviously I was wrong.

Thanks for your reply.

Hi all,

Please let me know if this is not the right place to ask this question.

I was trying to compile and build kernel 3.2.0, by following <Linux Administration - A Beginner's Guide> written by Wale Soyinka.

Error occurs after running the following command:

 # new-kernel-pkg -v --mkinitrd --depmod --install 3.2.0-custom
 initrdfile is /boot/initrd-3.2.0-custom.img
 running depmod for 3.2.0-custom
 creating initrd: /sbin/mkinitrd --allow-missing -f
 /boot/initrd-3.2.0-custom.img 3.2.0-custom
 found /boot/initrd-3.2.0-custom.img and using it with grubby
 adding 3.2.0-custom to /boot/grub/grub.conf
 /etc/lilo.conf does not exist, not running grubby

Does anyone ever run into this? How can I fix it?

Here is the link that I downloaded kernel from: http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.2.tar.bz2

 # uname -a
 Linux test_server 2.6.32-431.11.2.el6.x86_64 #1 SMP Tue Mar 25
 19:59:55 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

 # cat /etc/redhat-release
 CentOS release 6.5 (Final)

Please let me know if any other information is needed.

Thanks.

That method is not how to install kernels on CentOS ... CentOS uses RPMs for the kernel and here is how you would build one:

http://wiki.centos.org/HowTos/Custom_Kernel

However, there is very rarely a need for one to build their own custom kernel. If you really want a different kernel that is newer than the one in CentOS, ELRepo (http://www.elrepo.com) has a kernel-lt (long term kernel from kernel.org) and kernel-ml (main line kernel from kernel.org) ... and there is also a CentOS produced 3.10.x kernel in the Xen4CentOS repository.

If you want to learn how to create a new kernel as a learning exercise, the wiki link will help that, otherwise I would use one where a known and trusted entity is maintaining it secure.
