服务器评测
一、问题：
1、Linux虚拟机在A机的虚拟机中是NAT方式DHCP动态获取IP，设置了静态地址，IP地址不会发生变化，但是拷贝到B机上的虚拟机后，一直获取的时动态IP地址，无法得到静态IP。
2、执行/etc/init.d/network restart报错：
[root@master init.d]#./network restart

3、执行 systemctl restart network报错：

4、执行journalctl -xe报错：

二、解决：
Linux虚拟机从A拷贝到B后，MAC地址发生改变，但是配置文件中并没有同步修改，导致此问题。
1、首先执行ifconfig查看新的MAC地址：
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> 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<link>
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<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
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网卡对应的MAC地址为：00:0c:29:94:8e:a2，即ether对应的地址。
2、修改ens33网卡对应的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″
将HWADDR改为00:0c:29:94:8e:a2即可。
