VirtualBox安装CentOS的网络配置
$ 前言
- 镜像:CentOS-6.4-i386-minimal.iso
$ 配置目标
- 虚拟机里的CentOS既可以和主机互联,同时也可以连上外网
$ 碰到的错误
使用ping时,错误:
network is unreachable
service network restart时,错误:
Device eth0 does not seem to be present.
1.先配置好Host-only和Nat

virtualbox_2.jpg
2.查看文件cat /etc/udev/rules.d/70-persistent-net.rules
查看配置的上图的mac地址 是否与 文件中的ATTR[address]对应上.
如果不对应可以选择删除该文件重启，也可以直接修改该文件
[root@localhost network-scripts]# 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 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:e2:c7:25", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:bb:f0:79", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
3.进入 cd /etc/sysconfig/network-scripts目录
3.1 修改目录下的ifcfg-eth0 文件
该文件的DEVICE,HWADDR 应该与/etc/udev/rule.d/70-persistent-net.rules中的eth1一致.
我的ifcfg-eth0 文件,修改后为:
[root@localhost network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth1
HWADDR=08:00:27:E2:C7:25
TYPE=Ethernet
UUID=459bb09f-ce67-4276-a510-371dc8b8a12e
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
3.2 修改目录下的ifcfg-eth1 文件(没有则创建)
该文件的DEVICE,HWADDR 应该与/etc/udev/rule.d/70-persistent-net.rules中的eth2一致.
我的ifcfg-eth1 文件,修改后为:
[root@localhost network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth2
HWADDR=08:00:27:BB:F0:79
TYPE=Ethernet
UUID=459bb09f-ce67-4276-a510-371dc8b8a12e
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
4.重启服务, service network restart
执行ifconfig命令，输出
[root@localhost network-scripts]# ifconfig
