Rails服务器503服务不可用错误

Question

当我使用ruby script/server命令启动Rails服务器时，得到以下响应

=> Booting WEBrick
=> Rails 2.3.9 application starting on http://0.0.0.0:3000

我正在使用ProxyPreseve

<VirtualHost *:80>
 ProxyPreserveHost On
    ProxyPass / http://0.0.0.0:3000/
    ProxyPassReverse / http://0.0.0.0:3000/
    ServerName localhost
</VirtualHost>

并且我收到503服务不可用错误。 谁能告诉我我的应用程序有什么问题吗？

Rails版本：2.3.9 Ruby版本：1.8.7-p374捆绑版本：1.12.5 Gem版本：2.0.17
