1. Linux 内核源代码下载

git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

使用上述命令，得到源代码

3. 配置编译环境

sudo apt install gcc
sudo apt install make
sudo apt-get install pkg-config
sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install libncurses-dev
sudo apt-get install libelf-dev
sudo apt-get install libssl-dev

将编译镜像的工具安装进行安装

4. 编译（x86）

export ARCH=x86
make x86_64_defconfig
make menuconfig
# 选中下面的选项，保存退出
# Device Drivers  --->
# Block devices --->
#  <*>   RAM block device support
# (65536) Default RAM disk size (kbytes) 
make -j100

make menuconfig 直接选择退出就好了

5. 结果
