第2章:从内核出发
2.3节:编译内核 实验:
============================================================
系统环境:VM虚拟机 Ubuntu 14.04.3 LTS server版
任务:编译安装新的内核
注意:不要跨大版本,我在3.19版本内
耗时:2小时
所有版本的内核:
https://www.kernel.org/pub/linux/kernel/
当前系统内核版本
uname -r 3.19.0-25-generic
下载,解压,编译,安装Linux内核
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.19.8.tar.xz
sudo tar xf linux-3.19.8.tar.xz -C /usr/src/
cd /usr/src/linux-3.19.8/
sudo cp /boot/config-3.19.0-25-generic .config
sudo make -j 8 (编译,耗时80分钟)
echo $?
0
sudo make modules_install (安装模块,耗时7分钟)
echo $?
