【问题描述】：
对于我的菜鸟问题，我很抱歉，但我真的不明白出了什么问题！
我想在 vds 上运行我的应用程序。所以，为此我使用下一个：
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，我尝试使用由 Scaffold 创建的小型简单 Rails 应用程序进行配置。所以，这个应用程序工作正常（它使用 SQlite 并显示所有页面）。
然后我尝试启动使用 PostgreSQL 的应用程序。所以，我通过 capistrano 上传它，然后打印出来
$ cap deploy:start
* executing `deploy:start'
我也在我的服务器上打印
service nginx restart
所以，当我访问 ip 时，我只能获得旧应用程序的主要 rails 索引页面（如果我之前启动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。
我也试过了：
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
另外，当我尝试为我的应用启动或重新启动 nginx 时，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
怎么了？
我的配置文件：
Nginx.conf：
user root;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
