通常为了节省时间，在VMware中安装一套Linux后，会直接克隆一份出来使用。但在克隆REDHAT 6后，会发现网卡名称发生变化，比如eth0会变为eth1，下面介绍下克隆后的redhat 6，如何修改主机名、IP地址和网卡名称。

修改主机名（共2步）

hostname amto02

vi /etc/sysconfig/network -> 修改项：HOSTNAME=amto02

还原网卡名称为eth0：

[root@amto02 u01]# cat /etc/udev/rules.d/70-persistent-net.rules.bak # 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) (custom name provided by external tool)SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:27:be:dc", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"# PCI device 0x8086:0x100f (e1000)SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8a:8d:19", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

在该配置文件中会发现存在2条记录，第二条记录是克隆/复制虚拟机后，重新生成的一个mac地址（00:0c:29:8a:8d:19），因此，需要把就配置删除掉，也就是将第1条记录删除。并且第2条记录的最后面，将eth1改为eth0。修改后的配置文件为：

[root@amto02 u01]# 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 0x8086:0x100f (e1000)SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8a:8d:19", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

修改IP地址：

运行setup或者system-config-network，按照提示填写新的IP信息即可。

重启网卡服务：

service NetworkManager restart

service network restart
