debain9 修改静态ip地址

1.nano /etc/network/interfaces

2.将enp0s3注释掉，添加 eth0,如下所示

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

#allow-hotplug enp0s3

#iface enp0s3 inet dhcp

auto eth0

#allow-hotplug eth0

iface eth0 inet static

        address 192.168.10.12

        netmask 255.255.255.0

        gateway 192.168.10.1

#dhcp

3.修改grub 文件 

nano /etc/default/grub.bak  文件

修改内容如下：

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.

# For full documentation of the options in this file, see:

#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0

GRUB_TIMEOUT=5

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

GRUB_CMDLINE_LINUX_DEFAULT="quiet"

GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to

找到GRUB_CMDLINE_LINUX将参数的值设置为：GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

4.grub-mkconfig -o /boot/grub/grub.cfg重新生成GRUB引导配置文件，执行完成后，重启系统 ，如果linux系统是安装是虚拟机里面的如：virtualbox 中的，virtualbox 应该设置网络为桥接模式。

5.重启完成后，修改nano /etc/resolv.conf  增加：nameserver 8.8.8.8
