编辑网卡设备
1 vi /etc/udev/rules.d/70-persistent-net.rules
会看到有2块网卡eth0和eth1,eth0为原系统的,eth1为重新生成
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:e8:0a:33", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
//新生成网卡
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:5e:f5:f1", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
前面加#注释掉第一个网卡,更改第2个网卡为eth0,记录下mac地址。
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:e8:0a:33", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:5e:f5:f1", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
编辑完成保存退出。
2修改MAC
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改MAC地址”00:0c:29:e8:0a:33”为”00:0c:29:5e:f5:f1”
3重启系统
#reboot
重启系统问题就解决了。
