Divice eth0 dose not seem to be present ,delaying initalization解决办法

Posted 2020-08-21

因为整理硬盘里各种资料，就把VMware的虚拟系统移动到另外一个位置。但是启动之后不能上网，无法使用远程登录工具，通过ifconfig查看到网卡没有启动，然后启动网卡服务，报错：Divice eth0 dose not seem to be present ,delaying initalization。然后在网上找到解决办法，原因是eth0绑定的是原MAC地址导致，很顺利解决，记录一下：

故障表现;

ifconfig 没有看到网卡eth0，然后重启网卡服务，出现下面的报错：

#service network restart

Shutting down loopback insterface: [ OK ]

Bringing up loopback insterface: [ OK ]

Bringing up interface eth0: Divice eth0 dose not seem to be present ,delaying

initalization. [ FAILED ]

 

解决办法：

1、打开/etc/udev/rules.d/70-persistent-net.rulesnei内容如下：

#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 0×1022:0×2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*‘, ATTR{address}=="00:0c:29:a2:a9:5d", ATTR{type}==”1", KERNEL=="eth*", NAME="eth0"

# PCI device 0×1022:0×2000 (pcnet32)

SUBSYSTEM==“net”, ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:bd:a4:a8", ATTR{type}==“1", KERNEL=="eth*", NAME="eth1"

将etho网卡内容删掉或者注释掉，然后将NAME=后边的内容eth1改成eth0。

 

2、打开/etc/sysconfig/network-scripts/ifcfg-eth0修改MAC地址

#vi /etc/sysconfig/network-scripts/ifcfg-eth0

将HWADDR="00:0c:29:a2:a9:5d", 改成HWADDR="00:0c:29:bd:a4:a8"

 

3、最后，重启网络服务

#service network restart

 

附录：

还有一种比较暴力直接的方法，只是需要重启。删掉/etc/sysconfig/network-scripts/ifcfg-eth0文件中HWADDR这一行，删掉/etc/udev/rules.d/70-persistent-net.rules文件，然后重启机器，会自动生成。
