1/從官網下載kernel包文件；www.kernel.org
2/下載完成后解壓到/root下；查看文件大小；
#ll -h linux-4.12.tar.xz
查看分區空間及硬盤空間大?。皇欠褡銐颍?
3/解壓kernel包；
tar -xvf kernel-4.12.tar.xz
4/查看目錄大小
#du -sh linux-4.12
5/參考當前操作系統文件為模板進行調整

#mount -o rw /dev/sdc1 /mnt
#mount 可以看出只讀；
1下載kernel 源碼包
tar xf linux.XXX.xz
/root/linux.4.12/
2 生成配置模版文件
cp /boot/config.XXX /root/linux.4.12/.config
3 yum groupnstall "Development Tools"
yum install ncurses-devel
4 make menuconfig
選中NTFS
local version
5 make -j 4 && for i in {1..10};do echo -e "\a";sleep 1;done
6 make modules_install /lib/modules/`uname -r`
7 make install /boot/vmlinuz /boot/grub2/grub.cfg
在已經執行過編譯操作的內核源碼樹做重新編譯
? 需要事先清理操作：
make clean ：清理大多數編譯生成的文件，但會保留
config 文件等
make mrproper: 清理所有編譯生成的文件、config 及某
些備份文件
make distclean ：mrproper 、patches以及編輯器備份文件
? 刪除/lib/modules/ 目錄下不需要的內核庫文件
? 刪除/usr/src/linux/ 目錄下不需要的內核源碼
? 刪除/boot 目錄下啟動的內核和內核映像文件
? 更改grub 的配置文件，刪除不需要的內核啟動列表
編譯安裝
cd isolinux/

（b）make manuconfig
ls /lib/modules
make modules_install
自動添加到配置文建中
編譯：
cd /root/linux
ls net/
1、可以選擇性編譯
2、指定某個特定的目錄進行編譯
編譯的平臺 make ARHM
updatedb 更新
locate ntfs.ko
看文件
make modules_install
cd /root/linux-
切換 并進行操作 make install
reboot
重啟后選擇新的內核啟動
系統中的程序支持不支持內核，不支持將使用不了
ntfs 不支持，只讀更改不了{windows}
locate /lib/modules
選擇性編譯；
