centOS 5.8下，手动将静态ip修改为动态ip

<pre name="code" class="html">首先
mv /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0.bak
vi /etc/sysconfig/network-scripts/ifcfg-eth0
将内容修正成以下：
[root@mode ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0    


# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
BOOTPROTO=dhcp
NETMASK=255.255.255.0
HWADDR=00:0C:29:37:09:38
ONBOOT=yes
其中HWADDR值得获得：ifconfig eth0|grep HWaddr
保留以后
service network restart<pre name="code" class="html">首先
