linux重新编译内核

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

*** Unable to find the ncurses librariesor the

*** required header files.

*** 'make menuconfig' requires thencurses libraries.

***

*** Install ncurses (ncurses-devel) andtry again.

***

make[1]: *** [scripts/kconfig/dochecklxdialog] Error1

make: *** [menuconfig] Error 2

提示缺少了ncurses 库

apt-get install libncurses5-dev

# make xconfig

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
