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
