RubyOnRails中数据库配置

记得开始时间ROR的时候，遇到以一个很奇怪的问题，ROR的SERVER就是启动不了，显示的错误如下：

D:webroot1ster>ruby script/server
=> Booting WEBrick...
d:/ruby/lib/ruby/1.8/yaml.rb:133:in `load': syntax error on line 15, col 2: `  ho
        from d:/ruby/lib/ruby/1.8/yaml.rb:133:in `load'
        from d:/ruby/lib/ruby/gems/1.8/gems/rails-1.1.6/lib/initializer.rb:459:in
        from d:/ruby/lib/ruby/gems/1.8/gems/rails-1.1.6/lib/initializer.rb:181:in
        from d:/ruby/lib/ruby/gems/1.8/gems/rails-1.1.6/lib/initializer.rb:84:in
        from ....

        from d:/ruby/lib/ruby/gems/1.8/gems/rails-1.1.6/lib/initializer.rb:459:in

        from d:/ruby/lib/ruby/gems/1.8/gems/rails-1.1.6/lib/initializer.rb:84:in
        from ....

当时百思不得其解，后来发现是数据库的配置时出现错误，由于大意，少写了一个空格，正确的写法为：

引用

  development:
  adapter: mysql
  database: blog
  username: root
  password: 123456
  host: 127.0.0.1

PS：正确的写法：（：之后都有一个空格）
