一．问题说明

测试环境中出现的小问题，因为虚拟机之间经常复制来复制去，导致网卡配置这块的不一致现象。

配置文件的信息：

[root@ora10g network-scripts]# catifcfg-eth0

DEVICE="eth0"

NM_CONTROLLED="yes"

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=none

IPADDR=192.168.1.12

PREFIX=24

GATEWAY=192.168.1.1

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=no

NAME="System eth0"

UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03

HWADDR=08:00:27:BD:A6:ED

[root@ora10g network-scripts]# catifcfg-eth1

DEVICE="eth1"

NM_CONTROLLED="yes"

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=none

IPADDR=192.168.1.13

PREFIX=24

GATEWAY=192.168.1.1

DNS1=8.8.8.8

DEFROUTE=yes

IPV4_FAILURE_FATAL=yes

IPV6INIT=no

NAME="System eth1"

UUID=9c92fad9-6ecb-3e6c-eb4d-8a47c6f50c04

HWADDR=08:00:27:6E:86:10

这里对应的是网卡名称是eth0和eth1.

但是如果我们使用ifconfig 命令查看：

[root@ora10g network-scripts]# ifconfig -a
