Rails3 on Ubuntu 以及虚拟机Virtualbox 安装 笔记--可以节省你两天的折腾

[size=large]#在windows上安装Ubuntu 虚拟机[/size]
1. download Ubuntu desktop 32 bit (developer to use ubuntu desktop version may is better)
http://www.ubuntu.com/desktop/get-ubuntu/download

[size=large]2. install virtualbox and set the downloaded ubuntu iso as virtul disk[/size] driver and get server installed as step by step
http://www.virtualbox.org/wiki/Downloads
设置虚拟机内存为512M，可根据你机器内存来设置

[size=large]3. add another network card for virtual machine in box controller [/size]machine,
关闭虚拟机后，用 box manager给 给虚拟机增加一个网卡（在设置里面）
具体请细读

vim /etc/network/interfaces

auto eth1
iface eth1 inet static
address 192.168.56.5
netmask 255.255.255.0

sudo ifup eth1

reboot

外部有两个网卡，为虚拟机创建，为192.168.56.x字段
内部也有两个网卡， 一个为自动分配成10.0.2.15字段
外部网卡一个要设置为nat,一个设置为host-only

虚拟机安装要诀：
虚拟机安装后，要能够从windows xp host上能够访问到虚拟机，
本地有虚拟机的两张网卡， 内部有两个网卡， 一个为eth0,一个为eth1
把eth1设置成和host虚拟机两张网卡同一网段，就可以访问。

putty 上去虚拟机后，有时候发现有断掉的情形， 在make的时候，其他的时候还可以。
