我很抱歉我的noob问题，但我真的不明白什么是错的！Rails 3 - 不加载页面（nginx不启动）
我想在vds上运行我的应用程序。所以，对于我下次使用：
Ubuntu 10.04
PostgreSQL 9.1
Rails 3.1.3
Ruby 1.9.3p27
Nginx 1.0.11 (installed/compiled by passenger)
Phusion passenger 3.0.11
Capistrano
所以，我试图用已通过脚手架创建小型简单的Rails应用我的配置。所以，这个应用程序工作正常（它使用SQlite并显示所有页面）。
然后我试图启动我的应用程序，它使用PostgreSQL。所以，我通过Capistrano的上载，然后打印
$ cap deploy:start
* executing `deploy:start'
，也是我的服务器上我打印
service nginx restart
所以，当我访问IP我只得到我的旧应用程序的主轨索引页（如果我之前发布了非常简单的应用程序），或者它显示无法连接到服务器（否则），仅此而已。
此外，我试过了：
rails c production
> app.get("/")
然后我得到：
User Load (4.0ms) SELECT "users".* FROM "users" WHERE "users"."id" IS NULL LIMIT 1
CACHE (0.0ms) SELECT "users".* FROM "users" WHERE "users"."id" IS NULL LIMIT 1
User Load (0.0ms) SELECT "users".* FROM "users"
=> 500
而且，当我尝试启动或重新启动我的应用程序的nginx它不想工作：
$ initctl list | grep nginx
nginx stop/waiting
$ service nginx start
nginx start/running, process 30746
$ initctl list | grep nginx
nginx stop/waiting
出了什么问题？
我的配置文件：
Nginx.conf：

worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

我没有索引文件在我的'public'文件夹。另外，路线是正确的。我的应用程序在我的本地机器和heroku.com上效果很好。 – ExiRe
