曾经多次安装Ubuntu虚拟机，但是都没有将安装遇到的问题进行总计，这次准备搭建hadoop集群，因此又折腾起来。将安装遇到的问题，进行总结。
使用Ubuntu10.04LTS镜像。
安装完成后，先配置成国内更新源
由于默认情况下没有vim可用，因此先用gedit进行文本可视化编辑。
sudo gedit /etc/apt/sources.list
将需要的源拷贝进入此list中：

此时需要update及upgrade，否则会报如下错误：
Reading package lists... Done Building dependency tree Reading state information... Done Package vim is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
所以，update以及upgrade先：
sudo apt-get update sudo apt-get upgrade
update时候会报类似“wick”的错误提示，可以忽略。然后进入漫长的等待upgrade。
[后来发现，不用upgrade，直接update之后，就可以安装自己需要的工具了，如vim、git等]
sudo apt-get install git
sudo apt-get install vim
upgrade会将一些常见的基础以及依赖都更新下来。
PS:ubuntu官方的下载速度都可以在2.5MB/s，真是良心。
