【树莓派】Linux自动配置IP

时间：2022-01-09 00:01:37

由于需要配置多台树莓派设备，但需要将IP配置为静态IP，而一台一台手动执行比较慢，所以写了一份脚本，sudo 执行即可。

将下面内容复制在家目录下，命名为auto.sh

然后执行 sudo sh auto.sh 即可；

#!/bin/sh

sIP=`sudo ifconfig eth1 | grep inet | awk 'NR==1{print $2}'| awk -F ':' '{print $2}'`

sBcast=`sudo ifconfig eth1 | grep inet | awk 'NR==1{print $3}'| awk -F ':' '{print $2}'`

sMask=`sudo ifconfig eth1 | grep inet | awk 'NR==1{print $4}'| awk -F ':' '{print $2}'`

sGWP=`sudo ifconfig eth1 | grep inet | awk 'NR==1{print $2}'| awk -F ':' '{print $2}' | cut -d . -f -`

sDomain1="223.5.5.5"

sDomain2="223.6.6.6"

sDomain3="218.30.19.40"

sDomain4="61.134.1.4"

# sudo cp /etc/dhcpcd.conf /etc/dhcpcd.conf.default.bak

echo "IP="$sIP"\n"

echo "sBcast="$sBcast"\n"

echo "sMask="$sMask"\n"

echo "sMask="$sMask"\n"

echo "sMask="$sMask"\n"

echo "sDomain1="$sDomain1"\n"

echo "sDomain2="$sDomain2"\n"

echo "sDomain3="$sDomain3"\n"

echo "sDomain4="$sDomain4"\n"

sudo sed -i '$a interface eth1\n static ip_address='$sIP'/24\n static routers='$sGWP'.1\n #static domain_name_servers='$sDomain1' '$sDomain2'\n static domain_name_servers='$sDomain3' '$sDomain4'' /etc/dhcpcd.conf

# sudo sed -i '$a # static domain_name_servers='$sDomain3'' /etc/dhcpcd.conf

sudo sed -i '/interface eth1/i\\' /etc/dhcpcd.conf
