virtualbox 自带的网络配置模式要么选择host-only，要么bridge，对于经常使用virtualbox的同学一定想要像vmware一样的nat配置，既可以让host访问guest，又可以让guest访问外部网络
|
||
|
||
下面是安装步骤
|
||
|
||
1. 建立桥接网络
|
||
|
||
apt-get install bridge-utils
|
||
|
||
修改/etc/network/interfaces
|
||
|
||
增加以下内容：
|
||
|
||
####################################################
|
||
|
||
# VirtualBox NAT bridge
|
||
|
||
auto vnet0
|
||
|
||
iface vnet0 inet static
|
||
|
||
address 172.16.0.1
|
||
|
||
netmask 255.255.255.0
|
||
|
||
bridge_ports none
|
||
|
||
bridge_maxwait 0
|
||
|
||
bridge_fd 1
|
||
|
||
up iptables -t nat -I POSTROUTING -s 172.16.0.0/24 -j MASQUERADE
|
||
|
||
down iptables -t nat -D POSTROUTING -s 172.16.0.0/24 -j MASQUERADE
|
||
|
||
####################################################
|
||
|
||
up网卡
|
||
|
||
sudo ifup vnet0
|
||
|
||
2. 启用ip 转发
|
||
|
||
修改/etc/sysctl.conf 去掉这行的注释
|
||
|
||
# Uncomment the next line to enable packet forwarding for IPv4
|
||
|
||
net.ipv4.ip_forward=1
|
||
|
||
运行下面命令使其生效
|
||
|
||
sysctl -p
|
||
|
||
3. 为虚拟机搭建dhcp服务器和dns服务器
|
||
|
||
apt-get install dnsmasq
|
||
|
||
修改/etc/dnsmasq.conf
|
||
|
||
去掉下面的注释
|
||
|
||
# Include a another lot of configuration options.
|
||
|
||
#conf-file=/etc/dnsmasq.more.conf
|
||
|
||
conf-dir=/etc/dnsmasq.d
|
||
|
||
在/etc/dnsmasq.d/目录下面增加一个名为virtualbox的文件，内容为：
|
||
|
||
#######################################
|
||
|
||
interface=vnet0
|
||
|
||
dhcp-range=172.16.0.2,172.16.0.254,1h
|
||
|
||
dhcp-option=option:dns-server,172.16.0.1,208.67.222.222,208.67.220.220
|
||
|
||
dhcp-option=option:domain-name,precision-m65
|
||
|
||
# mac地址 , 主机名, 分配的ip
|
||
|
||
dhcp-host=08:08:27:00:00:02,vmxp,172.16.0.20 # Windows XP
|
||
|
||
dhcp-host=08:08:27:00:00:03,vmubuntu,172.16.0.30 # Ubuntu
|
||
|
||
#######################################
|
||
|
||
4.修改virtualbox 虚拟机配置
|
||
|
||
a. 打开虚拟机配置
|
||
|
||
b. 选择网络
|
||
|
||
c. 选择Attached to： "Bridged Adapter"
|
||
|
||
Name： "vnet0"
|
||
|
||
Advanced-> Mac Address：080827000002 #对应3步中virtualbox给虚拟机分配的mac地址，注意去掉冒号
|
||
|
||
d. 应用生效
|
||
|
||
启动虚拟机，看看是不是分配了正确的地址，上面配置在ubuntu 10.04 LTS上测试通过，其他发行版类似
