我有一个shell脚本来更改IP地址(在CentOS上),而不是手动更改它。这是脚本:
#!/bin/bash
# changeip.sh
usage(){
clear
echo "Usage: $0 newip"
echo "Example: $0 127.0.0.1"
exit 1
}
new_ip_value=$1
local_ip_value=$(ifconfig eth0|awk '/inet addr/ {split ($2,A,":"); print A[2]}')
# call usage() function if filename not supplied
[[ $# -eq 0 ]] && usage
echo "/etc/hosts"
echo "----------------------------------------------------------"
sed -ie 's/'$local_ip_value'/'$new_ip_value'/g' /etc/hosts
sed 's/'$local_ip_value'/'$new_ip_value'/g' /etc/hosts
echo ""
echo "/etc/sysconfig/network-scripts/ifcfg-eth0"
echo "----------------------------------------------------------"
sed -ie 's/'$local_ip_value'/'$new_ip_value'/' /etc/sysconfig/network-scripts/ifcfg-eth0
sed 's/'$local_ip_value'/'$new_ip_value'/' /etc/sysconfig/network-scripts/ifcfg-eth0
echo "The IP of $local_ip_value has successfully been changed to $new_ip_value."
service network restart
exit
我需要添加更多参数,例如:
等等。
任何机构都可以让我知道我应该如何修改脚本来添加这些细节吗?我的ifcfg-eth0最终应该是这样的:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="yes"
ONBOOT=yes
TYPE="Ethernet"
IPADDR=192.168.1.2
GATEWAY=192.168.1.1
感谢任何帮助!
谢谢!

在CentOS上更改IP地址的更好方法是使用system-network-config-cmd
工具。
例如:
#!/bin/bash
# Shell script input parsing here
system-config-network-cmd -i <<EOF
DeviceList.Ethernet.eth0.type=Ethernet
DeviceList.Ethernet.eth0.BootProto=static
DeviceList.Ethernet.eth0.OnBoot=True
DeviceList.Ethernet.eth0.NMControlled=True
DeviceList.Ethernet.eth0.Netmask=192.168.1.255
DeviceList.Ethernet.eth0.IP=${new_ip_value}
DeviceList.Ethernet.eth0.Gateway=192.168.1.1
ProfileList.default.ActiveDevices.1=eth0
EOF
service network stop
service network start
如果您以system-config-network-cmd -e
运行,则会转储现有配置。
