Linux分配不到IP地址 Device eth0 does not seem to be present, delaying initialization

• 分类: Linux • 标签: Linux

当我使用命令service network restart的时候,报Device eth0 does not seem to be present, delaying initialization这个错误.

然后我通过ifconfig,拿不到IP地址,显示如下内容,

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

原因是静态IP与旧设备的MAC地址绑定了.解决方案如下:

1 删除旧MAC地址： rm /etc/udev/rules.d/70-persistent-net.rules

2 重启 reboot

3 重启后会自动生成新的MAC地址 ，打开70-persistent-net.rules

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:fe:c1:03", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

记下其中的08:00:27:fe:c1:03MAC地址

4 编辑 /etc/sysconfig/network-scripts/ifcfg-eth0,修改MAC地址,同时删掉UUID这一行

5 重启网络服务service network restart
