3. MySQL
I have already install MYSQL server on my local machine.
So, I just install the drivers.

4. Install sqlite3 to create a sample
>sudo apt-get install libsqlite3-dev build-essential
>cd /home/luohua/work/rails
>rails new example

problem:
Installing rack (1.3.0) failure bundler raised an exception, are you offline?
solution: ignore right now
