问题：用VMware克隆CentOS 6.4后，发现系统内只有eth1,而且/etc/sysconfig/network-scripts/下只有，ifcfg-eth0文件，虽然可以上网，但无法设置静态IP。 ifconfig eth0 eth1: error fetching interface information: Device not found 解决：vi /etc/udev/rules.d/70-persistent-net.rules 显示为： # PCI device 0x8086:0x100f (e1000) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:48:85:9c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" 将 NAME="eth1" 改成NAME="eth0" 并将 ATTR{address}=="00:0c:29:48:85:9c",中的网卡地址改到 /etc/sysconfig/network-scripts/ifcfg-eth0 文件中，HWADDR="00:0C:29:48:85:9C"，使他们对应。 然后reboot ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:0C:29:48:85:9C inet addr:192.168.74.148 Bcast:192.168.74.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe48:859c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5032 errors:0 dropped:0 overruns:0 frame:0 TX packets:3674 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5762656 (5.4 MiB) TX bytes:209372 (204.4 KiB)
