mysql - 初学者Ruby / MSQL错误

http://localhost:3000/genre

我正在使用Instant Rails，我是第一次引入脚手架。

所以一切看起来都很好，我做了我自己的RoR页面等，今天我进来今天当我去localhost：3000我收到以下错误信息：

糟糕！ Google Chrome无法连接到localhost：3000

我将非常感谢您应该检查的任何建议。到目前为止，我知道要确认：

windows主机文件将127.0.0.1连接到localhost

我有一个更新，Mongrel服务器没有正确启动我创建的新应用程序，而不是一个打开的窗口，它只是运行一个脚本并关闭窗口而不确认它已经启动。

提前致谢。

这是Mongrel错误的详细信息：
