Vmware复制完好的linux目录后网卡操作
为了减少工作量，目前需要对已经安装好系统的linux，进行复制。采用直接复制目录的方式，那么后续会出现网卡配置冲突问题，那么如何解决呢？
OS 版本：
[root@kyeupdb ~]# lsb_release -a
LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: OracleServer
Description: Oracle Linux Server release 6.9
Release: 6.9
Codename: n/a
修改/etc/udev/rules.d/70-persistent-net.rules
- 查看现有的IP地址
[root@kyeupdb ~]# ifconfig

- 修改文件
[root@kyeupdb ~]# vi /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 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:f0:2d:c6", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:38:cc:a3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
把上面的eth0一行进行注释，并把eth1的名字修改成eth0，记录mac地址：00:50:56:38:cc:a3
修改网卡配置文件
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
HWADDR=00:50:56:38:cc:a3
IPADDR=192.168.1.20
PREFIX=24
GATEWAY=192.168.1.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
删除UUID，并把mac地址修改成记录的mac。
