[FAILED]CentOS Linux解决Device eth0 does not seem to be present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:89:97″,ATTR{type}==”1″,KERNEL==”eth*”,NAME=”eth0″# PCI device 0x1022:0x2000 (pcnet32)SUBSYSTEM==”net”,ATTR{address}==”00:0c:29:50:bd:17″,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。
