linux 下修改ip地址為靜態ip地址
1. 修改 /etc/sysconfig/network-scripts/ifcfg-eth0 檔案
DEVICE="eth0"
BOOTPROTO="static" #原值為dhcp
HWADDR="00:0c:29:ba:18:25"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
#以下是修改為靜態時需要加
IPADDR=192.168.71.132
GATEWAY=192.168.0.1
NETMASK=255.255.255.0
DNS1=202.106.195.68
DNS2=202.106.0.20
2. 重啟網路 : /etc/init.d/network restart 或者 service
network restart
ps 遇到的問題
重啟網路重啟不了 原因：GATEWAY: command not found /etc/sysconfig/network-scripts/ifcfg-eth0: line 15: GATEWAY: command not found Device eth0 does not seem to be present, delaying initialization.
解決辦法：
開啟/etc/udev/rules.d/70-persistent-net.rules內容如下面例子所示：
# vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
記錄下，eth1網絡卡的mac地址00:0c:29:50:bd:17
接下來，開啟/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
將 DEVICE="eth0" 改成 DEVICE="eth1" ,
將 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
最後，重啟網路
# service network restart
或者
# /etc/init.d/network restart
