The process of installing a new Linux kernel in a Debian system
This article introduces the relevant knowledge of "the process of installing the new Linux kernel in Debian system". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!
Download https://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.tar.bz2 and extract it to any directory, not necessarily in/usr/src.
Since I only needed a kernel source tree, I generated the configuration file using a simple make oldconfig
1. Generate config file
The code is as follows:
make oldconfig
Make oldconfig will prompt you incrementally with your existing configuration file, and finally use the system default value, that is, all the way to "enter", otherwise it may lead to some module dependencies, resulting in compilation failure.
2. Generating a compressed kernel image
The code is as follows:
make bzImage
This will generate a bzImage in the boot directory of your platform, such as my linux-2.6.28/arch/x86/boot/bzImage
3. compilation module
The code is as follows:
make modules
This is a very time-consuming step. Wait slowly.
4. Install kernel module
The code is as follows:
make modules_install
This creates the corresponding kernel version module in your/lib/modules/directory
5. install the kernel
The code is as follows:
make install
This will install our compiled kernel into the/boot directory
6. Create an initramfs file
The code is as follows:
update-initramfs -c -k 2.6.28
c for creating a new initramfs, k for specifying the kernel version
7. Update GRUB
The code is as follows:
update-grub
If not, you can manually repair/boot/grub/menu.lst. You can refer to the previous configuration file, just add the "title","root","kernel","initrd" fields. Note: update-grub Newly added kernel versions will appear before older versions.
8.reboot，enjoy it。
