ifconfig时只能看到io网卡，不能显示eth0网卡，重新启动网络服务（/etc/init.d/network restart）报错 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： vi /etc/udev/rules.d/70-persistent-net.rules
#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 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
