This article mainly introduces how to compile the RHEL kernel, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

RHEL kernel compilation steps:

1. To prepare the kernel to be compiled, the version must be more advanced than the version number currently in use. It can be downloaded from www.kernel.org/pub/RHEL/.

The kernel version number 2.6.26 used in this compilation

two。 RHEL-2.6.26.tar.gz cp / usr/src

3.tar-xzvf RHEL.2.6.26.tar.gz

4.ln-s RHEL.2.6.26 RHEL builds soft links

Pwd determines that it is in the / usr/src/RHEL directory

5.make mrproper determines that there are no. * and .o files in the system. If the kernel has been compiled before, the above files will be generated and the compilation will fail.

6.make config traditional text kernel compilation mode, but cannot be returned after an error.

Make menuconfig text-based kernel compilation mode, error can be returned, it is recommended to use these modes.

Make xconfig kernel compilation mode based on graphics

Make oldconfig makes only minor changes to the current kernel

7.make dep determines dependencies,

8.make clean determines that there are no files in the kernel source file

9.make modules compiles kernel module

10.make modules_install installs the compiled kernel module

11.depmod-a create module link

twelve。 Make a new link:

Cd / usr/src/RHEL

Cp System.map / boot/System.map-2.6.26

Cp arch/i386/boot/bzImage / boot/vmlinuz

Cd / boot

New-kernel-pkg-mkinitrd-depmod-install 2.6.26

13.vi / boot/grub/menu.lst modifies the configuration file booted with grub

Vi / boot/lilo.conf modifies the configuration file booted with LILO

Cd / usr/src/RHEL/

Make install

14. Init 6 restarts the system.

Note: because it is installed in a virtual machine, it is important to pay attention to the kernel support for scsi when compiling the RHEL kernel.

Thank you for reading this article carefully. I hope the article "how to compile the RHEL Kernel" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
