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：
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：

看起来您的数据库尚未配置。查看APP_ROOT / config / database.yml文件，查找是否已创建与开发环境对应的数据库。设置数据库后，您的代码应运行正常。
