跳转到目录 点这里
编译和安装busybox
make ARCH=x86_64 menuconfig Settings ---> Build Options -[ ] Build static binary (no shared libs) (NEW) make ARCH=x86_64 make install
创建根文件目录 fsroot
mkdir -p /kernel-debug/fsroot/
写一个脚本来人创建必要的目录
install.sh
mkdir -p /kernel-debug/fsroot/lib mkdir -p /kernel-debug/fsroot/mnt mkdir -p /kernel-debug/fsroot/home mkdir -p /kernel-debug/fsroot/proc mkdir -p /kernel-debug/fsroot/root mkdir -p /kernel-debug/fsroot/sys mkdir -p /kernel-debug/fsroot/tmp mkdir -p /kernel-debug/fsroot/dev mkdir -p /kernel-debug/fsroot/var/lock mkdir -p /kernel-debug/fsroot/var/log mkdir -p /kernel-debug/fsroot/var/run mkdir -p /kernel-debug/fsroot/var/tmp mkdir -p /kernel-debug/fsroot/etc/init.d/ touch /kernel-debug/fsroot/etc/inittab touch /kernel-debug/fsroot/etc/init.d/rcS touch /kernel-debug/fsroot/etc/fstab touch /kernel-debug/fsroot/etc/profile touch /kernel-debug/fsroot/etc/init.d/ifconfig-all chmod 755 /kernel-debug/fsroot/etc/inittab chmod 755 /kernel-debug/fsroot/etc/init.d/rcS chmod 755 /kernel-debug/fsroot/etc/fstab chmod 755 /kernel-debug/fsroot/etc/profile chmod 755 /kernel-debug/fsroot/etc/init.d/ifconfig-all
sh install.sh
[hun-hh fsroot]# sh /kernel-debug/fsroot/install.sh
看一下目录结构
[hun-hh fsroot]# tree
├── dev ├── etc │ ├── eth0-setting │ ├── eth1-setting │ ├── fstab │ ├── init.d │ │ ├── ifconfig-all │ │ ├── ifconfig-eth0 │ │ ├── ifconfig-eth1 │ │ └── rcS │ ├── inittab │ └── profile ├── home ├── install.sh ├── lib ├── mnt ├── proc ├── root ├── sys ├── tmp └── var ├── lock ├── log ├── run └── tmp
复制到 busybox 到自己根文件目录
cp -a /kernel-debug/busybox-1.32.0/_install/* /kernel-debug/fsroot
配置一些基本的配置文件
