内核编译安装系统
1/从官网下载kernel包文件；www.kernel.org
2/下载完成后解压到/root下；查看文件大小；
#ll -h linux-4.12.tar.xz
查看分区空间及硬盘空间大小；是否足够；
3/解压kernel包；
tar -xvf kernel-4.12.tar.xz
4/查看目录大小
#du -sh linux-4.12
5/参考当前操作系统文件为模板进行调整
[root@centos7 ~]#ll /boot/vmlinuz-3.10.0-514.el7.x86_64 -rwxr-xr-x. 1 root root 5392080 Nov 23 2016 /boot/vmlinuz-3.10.0-514.el7.x86_64

6/将配置文件拷贝到/root/linux-4.12/.config
[root@centos7 boot]#cp config-3.10.0-514.el7.x86_64 /root/linux-4.12/.config
[root@centos7 boot]#wc -l /root/linux-4.12/.config
5848 /root/linux-4.12/.config
查看文件行数
配置文件行数较多，用菜单工具定制内核选项；
需安装开发工具包组
[root@centos7 boot]#yum install "Development tools"
[root@centos7 boot]#yum groupinstall "Development tools"
包组安装完成后，运行软件工具 make menuconfig
进入到/linux-4.12目录下运行软件工具；
[root@centos7 ~]#ls

ntfs格式linux只支持只读；
#mount -o rw /dev/sdc1 /mnt
#mount 可以看出只读；
1下载kernel 源码包
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
选中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
在已经执行过编译操作的内核源码树做重新编译
需要事先清理操作：
make clean ：清理大多数编译生成的文件，但会保留
config 文件等
make mrproper: 清理所有编译生成的文件、config 及某
些备份文件
make distclean ：mrproper 、patches以及编辑器备份文件
删除/lib/modules/ 目录下不需要的内核库文件
删除/usr/src/linux/ 目录下不需要的内核源码
删除/boot 目录下启动的内核和内核映像文件
更改grub 的配置文件，删除不需要的内核启动列表
编译安装
cd isolinux/
ll vmlinuz 内核文件
跟boot目录下的一样
出厂版本，及日期
上传 linux-4.12.tar.xz文件(rz)
占用10G多的空间
解开包--解压缩
tar xf linux---
#du -sh linux-4.12
ll /boot/vmlinuz 参考文件进行修改
cd /boot
config---- 配置文件，
ls /lib/modules
更新数据库updatedb
locate ntfs.ko
ls
locate ext4.ko
菜单工具
安装开发工具包组
yum groupinstall "development Tools“
make menuconfig 运行软件工具
install 安装缺少的包文件
uname -r
内核版本
fIle system
文件系统
DOS/FAT/NT ntfs
make -j 4 有四颗cpu 四线程
cd /root/lnux---
ls
查看生成的目录
（b）make manuconfig
ls /lib/modules
make modules_install
自动添加到配置文建中
编译：
cd /root/linux
ls net/
1、可以选择性编译
2、指定某个特定的目录进行编译
编译的平台 make ARHM
updatedb 更新
locate ntfs.ko
看文件
make modules_install
cd /root/linux-
切换 并进行操作 make install
reboot
重启后选择新的内核启动
系统中的程序支持不支持内核，不支持将使用不了
ntfs 不支持，只读更改不了{windows}
locate /lib/modules
选择性编译；
#############################################make clean 清除文件
