好玩的BusyBox

編譯busybox
 一、安裝編譯環境
  yum -y install gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl openssl-devel systemd-devel zlib-devel libmcrypt-devel glibc-static ncurses-devel。
 二、下載busybox源碼包
  wget https://busybox.net/downloads/busybox-1.30.0.tar.bz2
 三、解壓
 四、cd busybox-1.30.0/
 五、make menuconfig 按下面選擇，把busybox編譯也靜態二進制、不用共享庫 Busybox Settings -->Build Options -->[*] Build BusyBox as a static binary (no shared libs) (其餘功能選項根據本身需求)

 六、make && make install 若是出錯，執行make clean後，從新執行上面命令

 七、mkdir /mnt/sysroot/
 八、把make install安裝完成生成的_install目錄下文件考入根系統下就能夠使用了   cp -a _install/ /mnt/sysroot/
