System clipping centos6.8 with network function

Installation Environment: centos6.8,kernel:2.6.32-642.4.2.el6.x86_64

Target host: Minimized home-made Linux hosts

Host: A self-made, minimized Linux host made in that Linux host, and the following is done in the host

The newly added disk configuration information is as follows:

1, add a new hard disk in the virtual machine, and remember the storage location of the hard disk, in order to be used, divided into two zones, respectively for the boot and/

Mkfs.ext4/dev/sdb1

Mkfs.ext4/dev/sdb2

2, mount the partition, mount location should not be created first

# Mount/dev/sdb1/mnt/boot

# Mount/dev/sdb2/mnt/sysroot

3. Copy the Linux kernel, and initramfs.img to/mnt/boot/

# cp/boot/vmlinuz-' Uname-r '/mnt/boot/vmlinuz

# cp/boot/initramfs-' Uname-r '. img/mnt/boot/initramfs.img

4. Install Grub to/dev/sdb

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

Note: Because this is mounted to the/MNT directory, the MNT is treated as the root of grub

5, copy some commands to the cropping system, through the bincp.sh script

# bash/root/scripts/bincp.sh

Bash

Mount

Insmod

Cat

Vim

Ls

Cd

Ifconfig

Mkdir

Touch

Umount

Ping

Tree

Quit

6. Copy the NIC driver to the past

View all drivers, e1000 is the NIC driver

# Lsmod

View the details of the e1000 driver to see the location of the driver file

# Modinfo e1000

# mkdir/mnt/sysroot/lib/modules/-PV

# cp/lib/modules/' Uname-r '/kernel/drivers/net/e1000/e1000.ko/mnt/sysroot/lib/modules/

Note: Lib/modules folder should not be created beforehand

7. Create the corresponding directory under the target host root

# Mkdir-pv/mnt/sysroot/{etc,etc/rc.d,boot,dev,bin,lib,sbin,home,root,var,usr,tmp,mnt,media,proc,sys}

8. Establish a grub profile for the target host to enable the system to boot

# vim/mnt/boot/grub/grub.conf

Default=0

Timeout=3

Title Siyu

Root (hd0,0)

Kernel/vmlinuz ro root=/dev/sda2 selinux=0 init=/sbin/init

INITRD initramfs.img

Note: Here the INITRD instruction and kernel value should be the same as the 4th step, because the init value here is/sbin/init, so you need to create the/sbin/init file and add the appropriate system initialization command, if you do not want to use the init file, then init=/ Bin/bash, but unable to implement network functions

9. Initialize the system file init and give execute permission

# Vim/mnt/sysroot/sbin/init

#!/bin/bash

Echo-e "\ t \033[34m linux \033[3m"

Mount-n-T proc Proc/proc

Mount-n-T Sysfs Sysfs/sys

Insmod/lib/modules/e1000.ko

Ifconfig eth0 192.168.1.4/24

Ifconfig Lo 127.0.0.0/8

Mount-n-T remount,rw/dev/sda2/

/bin/bash

# chmod +x/mnt/sysroot/sbin/init

10. Test the SDB drive into another virtual machine

Create a new virtual machine with the following result, the disk file will be the same as the newly added disk for host

650) this.width=650; "src=" Http://note.youdao.com/yws/res/2557/95DB749BEE49428FAA4B3CBCABAF6EEE "alt=" 95db749bee49428faa4b3cbcabaf6eee "/>

11. Use init config file and network configuration is successful

650) this.width=650; "src=" http://note.youdao.com/yws/res/2556/23A2BD93EAA047D68A56A5F66C56B556 "alt=" 23a2bd93eaa047d68a56a5f66c56b556 "/>

Using the script one-click execution

The host root directory used here is sysroot, mounted under MNT, boot partition boot, mount to/mnt/boot
