此标题已经是有人写过的了.但是为什么拿来重写?
我复制完,没有发现有eth1这个网卡
为什么呢?需要选中 重新初始化所有网卡的MAC地址
后来我又尝试了另一种方法
vi /etc/udev/rules.d/70-persistent-net.rules 删除原eth0, 然后把eth1改成eth0
vi /etc/sysconfig/network-scripts/ifcfg-eth0 直接改成 的MAC地址
先粘贴原文(也可直接访问上面链接)
在VMware里克隆出来的CentOS Linux。。
ifconfig...没有看到eth0.。然后重启网卡又报下面错误。
故障现象：
service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]
解决办法：
首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：
# 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"
记录下，eth1网卡的mac地址00:0c:29:50:bd:17
接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
最后，重启网络
# service network restart
或者
# /etc/init.d/network restart
正常了。
CentOS Linux解决Device eth0 does not seem to be present 但是没有发现eth1
