1、查看网卡信息

cat /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 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:56:9e:1d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:56:9e:27", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

2、复制第一个网卡的信息

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1

#修改 DEVICE:eth0 -> DEVICE:eth1
#修改 HWADDR:00:0c:29:56:9e:1d -> HWADDR:00:0c:29:56:9e:27
#修改IP信息

3、重启网络

service network restart
