linux下修改IP、DNS、路由命令行设置(1)

ubuntu 版本命令行设置IP

cat /etc/network/interfaces

# This file describes the network interfaces available on your system

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

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

auto eth0

iface eth0 inet static

address 192.168.1.104

netmask 255.255.255.0

network 192.168.1.0

broadcast 192.168.1.255

gateway 192.168.1.2

# dns-* options are implemented by the resolvconf package, if installed

dns-nameservers 58.22.96.66 218.104.128.106 202.101.138.8

dns-search .COM

重启网卡: /etc/init.d/networking restatr

redhat linux版本命令行设置IP:

ifconfig eth0 新ip

然后编辑/etc/sysconfig/network-scripts/ifcfg-eth0，修改ip

一、修改IP地址

[aeolus@db network-scripts]$ vi ifcfg-eth0

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR=219.136.241.211

NETMASK=255.255.255.128

GATEWAY=219.136.241.254

二、修改网关

vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=Aaron

GATEWAY=192.168.1.1

三、修改DNS

[aeolus@db etc]$ vi resolv.conf

nameserver 202.96.128.68

nameserver 219.136.241.206

四、重新启动网络配置

/etc/init.d/network restart

五、例子

1、修改ip地址

即时生效:

# ifconfig eth0 192.168.0.20 netmask 255.255.255.0

启动生效:

修改/etc/sysconfig/network-scripts/ifcfg-eth0
