Making Linux system based on grub2+busybo+linux-2.6.36 under X86 platform

X86 platform based on the grub2+busybo+linux-2.6.36 making Linux system

First, download the kernel source code, GRUB2 source code, and BusyBox Source:

1. Download GRUB2 Source code

ftp://ftp.gnu.org/gnu/grub/to find the desired version, here to choose grub-1.99.tar.gz

1. Download BusyBox Source code

http://www.busybox.net/downloads/to find the desired version, here to choose busybox-1.22.1.tar.bz2

1. Download linux-2.6.36 Kernel source code

https://www.kernel.org/to find the desired version, here to choose LINUX-2.6.36.TAR.XZ

Second, compile the source code

Create the directory/mylinux and copy the source tarball to the/mylinux.

1. Compiling GRUB2

Decompression: TAR–XF grub-1.99.tar.gz

Switching paths for compiling: CD grub-1.97

Compile:./configure &&make&&make Install

After compiling, the genetic execution file is in the/usr/local/sbin directory

2. Compiling BusyBox

Decompression: TAR–XF busybox-1.22.1.tar.bz2

Switching paths for compiling: CD busybox-1.22.1

Configure compilation options: Make Menuconfig

Note: When you configure the compile option, you want to select the USE/USR, or make install, copy the resulting execution file to/usr in the corresponding directory. Other configurations are determined according to your needs

Compiling:make&& make install

Note: The target file generated by the compilation will be output to: _install directory

3. compile linux-2.6.36 Kernel code

Decompression: TAR–XF LINUX-2.6.36.TAR.XZ

Toggle Compilation path: CD linux-2.6.36

To configure compilation options:

Copy the configuration of the current system as the default configuration: cp/boot/config-xxx. config

Make Menuconfig Modify the kernel configuration to suit your needs

Compiling: Make && make modules && make Modules_install && make install

Third, make the root file system directory

Create directory: Mkdir–p/mylinux/sysroot

Toggle Path: Cd/mylinux/sysroot

Create root directory: mkdir-p boot dev etc home linuxrc proc Root tmp usr var lib

Copy the necessary device files from the system: Console Kmem mem Ram stderr stdout tty0 ttyS0 Zero

Fd/loop null random stdin TTY tty1 urandom

Note: You can also create your own with the Mknod command

Copy executable file: cp-raf/mylinux/busybox-1.22.1/_install/*/mylinux/sysroot/

Copy kernel module: cp–raf/lib/modules/linux-2.6.36xxx/*/mylinux/sysroot/lib/

Write system configuration file: Cd/mylinux/sysroot/etc

Create the following file: busybox.conf fstab Group INIT.D inittab issue MOTD mtab passwd profile resolv.conf Shadow shadow-

Create directory: INIT.D

1. Busybox.conf is empty
2. Fstab

/dev/sda1/boot ext3 defaults 0 0

Debugfs/sys/kernel/debug Debugfs noauto 0 0

1. Create the RCS startup script file under the INIT.D directory, plus the executable permissions, as follows:

#! /bin/sh

Mount-o REMOUNT,RW/

/bin/mount-a

>/etc/mtab

Four, make system boot disk

Note: Temporarily on the virtual machine to operate, the actual hard disk is also a reason

1, add a hard disk on the virtual machine, the size is set to 8G.

The newly added drive can be seen through the command fdisk–l:

Partition not yet in progress

2, the new hard disk with fdisk command partition, partition as follows:

3. Format the new disk partition:

Mkfs.ext3/dev/sdb1

Mkfs.ext3/dev/sdb2

4. Create mount Directory:

Mkdir–p/mnt/boot/mnt/sysroot

5. Mount the new disk

Mount/dev/sdb1/mnt/boot

mount/dev/sdb2/mnt/sysroot/

6. Copy the corresponding files to the new disk:

Cp/boot/vmlinuz-2.6.36-12-xxx/mnt/boot/vmlinuz

Cp/boot/initrd-2.6.36-12-xxx/mnt/boot/initrd

cp-raf/mylinux/rootfs/*/mnt/sysroot/

7. Join Grub Boot Boot:

Grub-install--root-directory=/mnt/dev/sdb

8. Create Grub Boot Menu:

/mnt/boot/grub/grub.cfg:

Set default=0

Set timeout=5

Menuentry "Gnu/linux, with Linux 3.16.3-12-default" {

Set root= (hd0,1)

Linux/vmlinuz

Initrd/initrd

}

9. Unmount the disk:

Umount/mnt/boot

Umount/mnt/sysroot

Four, to here the system is finished, the new system has been written to disk, the new disk as a system disk, you can boot the system.
