生活随笔收集整理的這篇文章主要介紹了 linux跨ip拷贝,Linux的虚拟机拷贝到另外的操作系统时，NAT方式的静态IP无效，一直是获取的DHCP动态地址... 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

一、問題：

1、Linux虛擬機在A機的虛擬機中是NAT方式DHCP動態(tài)獲取IP，設(shè)置了靜態(tài)地址，IP地址不會發(fā)生變化，但是拷貝到B機上的虛擬機后，一直獲取的時動態(tài)IP地址，無法得到靜態(tài)IP。

2、執(zhí)行/etc/init.d/network restart報錯：

[root@master init.d]#./network restart

正在關(guān)閉接口 ens33：錯誤:[/etc/sysconfig/network-scripts/ifdown-eth]設(shè)備具有 MAC 地址00:00:00:00:00:00

00:0C:29:94:8E:A2，而不是配置的地址00:0C:29:8B:9A:F2。忽略。

[失敗]

正在關(guān)閉環(huán)回接口：Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'

Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'

[確定]

正在打開環(huán)回接口：Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'

Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'

[確定]

正在打開接口 ens33：錯誤：沒有找到可用于連接'ens33'的設(shè)備。

[失敗]

3、執(zhí)行 systemctl restart network報錯：

Jobfor network.service failed.See"systemctl status network.service" and "journalctl -xe"for details.

4、執(zhí)行journalctl -xe報錯：

5月2600:29:28 master /etc/sysconfig/network-scripts/ifdown-eth[1350]:設(shè)備具有 MAC 地址00:00:00:00:00:00

二、解決：

Linux虛擬機從A拷貝到B后，MAC地址發(fā)生改變，但是配置文件中并沒有同步修改，導(dǎo)致此問題。

1、首先執(zhí)行ifconfig查看新的MAC地址：

ens33: flags=4163 mtu 1500

inet 192.168.130.109 netmask 255.255.255.0 broadcast 192.168.130.255

inet6 fe80::20c:29ff:fe94:8ea2 prefixlen 64 scopeid 0x20

ether 00:0c:29:94:8e:a2 txqueuelen 1000(Ethernet)

RX packets 550 bytes 48524(47.3KiB)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 604 bytes 94343(92.1KiB)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

lo: flags=73 mtu 65536

inet 127.0.0.1 netmask 255.0.0.0

inet6 ::1 prefixlen 128 scopeid 0x10

loop txqueuelen 0(LocalLoopback)

RX packets 8 bytes 800(800.0 B)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 8 bytes 800(800.0 B)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

可以看出ens33網(wǎng)卡對應(yīng)的MAC地址為：00:0c:29:94:8e:a2，即ether對應(yīng)的地址。

2、修改ens33網(wǎng)卡對應(yīng)的MAC地址

vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE="Ethernet"

DEFROUTE="yes"

IPV4_FAILURE_FATAL="no"

NAME="ens33"

UUID="707084bc-d3aa-483f-878b-c93e6abf4a07"

ONBOOT="yes"

HWADDR="00:0C:29:8B:9A:F2"

BOOTPROTO="static"

NM_CONTROLLED="yes"

IPADDR="192.168.130.101"

NETMASK="255.255.255.0"

GATEWAY="192.168.130.2"

將HWADDR改為00:0c:29:94:8e:a2即可。
