查看/etc/sysconfig/network-scripts/目录下文件。
cd /etc/sysconfig/network-scripts/
ls
如果目录下只有ifcfg-lo,没有ifcfg-eth0,输入以下命令查看,显示eth0和lo。
ifconfig -a
如果显示eth1和lo,输入以下命令。
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 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:df:ab:a9", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:18:be:20", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:fc:33:0b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
把NAME的值eth0与eth1交换一下就OK了。
回到/etc/sysconfig/network-scripts目录,复制 ifcfg-lo的配置文件,拷贝到新建的ifcfg-eth0。打开ifcfg-eth0修改配置信息。
cd /etc/sysconfig/network-scripts
cp ifcfg-lo ifcfg-eth0
vim ifcfg-eth0
根据自己虚拟机情况修改成以下类似配置信息。
DEVICE=eth0
IPADDR=192.168.245.122
NETMASK=255.255.255.0
GATEWAY=192.168.245.2
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
ONBOOT=yes
重启。
reboot
