This article mainly introduces how linux compiles the kernel, which 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.

What is Linux system Linux is a free-to-use and free-spread UNIX-like operating system, is a POSIX-based multi-user, multi-task, multi-threaded and multi-CPU operating system, using Linux can run major Unix tools, applications and network protocols.

1. Download the required kernel version

2. Upload to the operating system

3. Decompress to / usr/src directory

For example: 3.19 kernel

Tar-xvf linux-3.19.tar.xz-C / usr/src

4. Create a connection

Cd / usr/src

Ln-sv / usr/src/linux-3.19 Linux

5. Set the kernel

Cd / usr/src/linux

Make menuconfig

In this step, it is best to copy a previously run .config file and make changes on this file, otherwise, the restart may not work.

Such as the following:

Cp / boot/config-3.10.0-123.el7.x86_64 / usr/src/linux/.config

6. Compile the kernel

Make-may range from 1 hour to 3 hours.

Make modules_install

Make install

7. Restart.

Deploy kernel source code

Open the terminal and change the user rights to root. To do this, enter sudo su at the terminal, and then follow the prompts to enter the password. Determine whether the root user uses the whoami command, and if the output is root, it has been switched to the root account.

Type mv linux-2.6.36.tar.gz / usr/src to move the downloaded kernel source code files to the / usr/src directory.

Enter cd / usr/src to change to this directory.

Type tar zxvf linux-2.6.36.tar.gz to extract the kernel package, and the generated source code is placed in the linux-2.6.36 directory.

Enter cd linux-2.6.36 and change to that directory.

Enter cp / boot/config-, and press Tab, and the system will automatically fill in the qualified file name in that directory, and then continue typing .config in order to use the original configuration file in the boot directory.
