一、linux内核
1.查看linux内核版本
uname -r
2.下载对应的linux内核
https://www.kernel.org/pub/linux/kernel/
将内核文件夹解压到/usr/src/
cd /usr/src/linux***(你的内核文件夹)
#make menuconfig
这里会出现错误：
HOSTCC scripts/basic/fixdep
HOSTCC scripts/basic/docproc
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/kxgettext.o

*** required header files.

3.解决问题 继续
#sudo make menuconfig
# 選擇下面的 module
# Networking support ->
# Networking options ->
# Network packet filtering framework (Netfilter) ->
# IP: Netfilter Configuration
4.重新编译系统（比较久）
sudo make all
5.编译模块
sudo make modules_install
这里会出现错误
#make menuconfig
然后进入Loadable module support, 选中Enable loadable module support
可以了 继续编译模块
sudo make modules_install
sudo make install
