Fedora配置静态IP

    早上要写个自动化的脚本，从DHCP切换到Static具体不多说了，直接贴脚本吧！

#!/bin/sh

# Get current network configration
ETH=`ip route | awk '$5 ~ /eth[0-9]/ {print $5}'`
ADDR=`ifconfig $ETH | grep "inet addr" | awk -F: '{ print $2 }'| awk '{ print $1 }'`
BCAST=`ifconfig $ETH | grep "inet addr" | awk -F: '{ print $3 }'| awk '{ print $1}'`
MASK=`ifconfig $ETH | grep "inet addr" | awk -F: '{ print $4 }'`
GATEWAY=`ip route | grep default | awk '{ printf $3 }'`

FILE=/etc/sysconfig/network-scripts/ifcfg-$ETH

# Modify network configration file
cp $FILE $FILE.bak
sed -i 's/dhcp/static/g' $FILE
echo "BROADCAST="$BCAST >> $FILE
echo "IPADDR="$ADDR >> $FILE
echo "NETMASK="$MASK >> $FILE
echo "GATEWAY="$GATEWAY >> $FILE

# Restart network service
service network restart
if [ $? -ne 0 ]; then
    echo "Failed to switch dhcp to static, reverse to dhcp now!"
    cp $FILE.bak $FILE
    service network restart
else
    echo "Success to switch dhcp to static!"
fi

    脚本相当简单，就不多说了！
