有时候需要频繁在静态ip和动态ip中切换, 这时使用脚本就比较方便
netsh
查询名称
netsh interface ipv4 show interfaces
设置静态ip
netsh interface ip set address name="本地连接" source=static addr=10.101.192.3 mask=255.255.255.0 gateway=10.101.192.1 1
netsh interface ip set dns name="本地连接" source=static addr=202.196.64.1
netsh interface ip add dns name="本地连接" source=static addr=114.114.114.114
设置动态ip
netsh interface ip set address name="本地连接" source=dhcp
netsh interface ip set dns name="本地连接" source=dhcp
powershell
查询名称
Get-NetAdapter
比如要设置的接口是3
设置静态ip
New-NetIPAddress -InterfaceIndex 3 -IPAddress 10.1.4.220 -PrefixLength 24 -DefaultGateway 10.1.4.254
Set-DnsClientServerAddress -InterfaceIndex 3 -ServerAddresses("114.114.114.114")
设置dhcp
Set-NetIPInterface -InterfaceIndex 3 -dhcp enabled
Set-DnsClientServerAddress -InterfaceIndex 3 -ResetServerAddresses
ubuntu
编辑文件
vi /etc/network/interfaces
静态ip
auto eth0
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 4.4.4.4
dns-nameservers 8.8.8.8
dhcp
auto eth0
iface eth0 inet dhcp
dns配置, /etc/resolv.conf
nameserver 8.8.8.8 # Replace with your nameserver ip
nameserver 4.4.4.4 # Replace with your nameserver ip
重启
systemctl restart network
ubuntu 17
编辑netplan文件夹下的文件
vi /etc/netplan/01-netcfg.yaml
添加以下内容, 设置的网卡名称, 如eth0
network:
version: 2
renderer: networkd
ethernets:
eth0:
dhcp4: no
addresses: [192.168.2.2/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
其中dhcp4配置为yes, 则为动态ip
应用网络配置
netplan apply
CentOS
编辑配置
vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改为以下内容
HWADDR=$SOMETHING
TYPE=Ethernet
BOOTPROTO=none // turns off DHCP
IPADDR=192.168.2.2 // set your IP
PREFIX=24 // subnet mask
GATEWAY=192.168.2.254
DNS1=1.1.1.2 // set your own DNS
DNS2=1.0.0.2
DNS3=9.9.9.9
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=eth0
DEVICE=eth0
ONBOOT=yes // starts on boot
其中BOOTPROTO设置为none或者static为静态ip, DHCP为动态ip
应用配置
/etc/init.d/network restart
# or
systemctl restart network
