Source code compilation and kernel upgrade

Recently, I am working on the operating system to refresh the items that should be recorded a long time ago and write them for future reference. No matter what it is, it may be forgotten after a long time.

No, go to the topic.

1. Download source code

Https://www.kernel.org/pub/linux/kernel/v3.x/

2. Extract

Tar zxvf linux-3.8.8.tar.gz

3. Enter the decompressed directory.

Cd/usr/src/linux-3.8.8

The following commands use The sudo permission

4. Generate a configuration file

Make oldconfigure

5. Compile (it takes a long time)

Make

6. Install the module and upgrade the kernel.

Make modules_install install
