新手求助：建了个rails项目，直接访问localhost:3000是正确的，但是用nginx+passenger后，就说“table not found”

配置文件如下:

development.rb
Demo::Application.configure do
# Settings specified here will take precedence over those in config/application.rb

# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false

# Log error messages when you accidentally call methods on nil.
config.whiny_nils = true

# Show full error reports and disable caching
config.consider_all_requests_local = true
config.action_controller.perform_caching = false

# Don't care if the mailer can't send
config.action_mailer.raise_delivery_errors = false
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => "domain.of.sender.net",
:authentication => "plain",
:user_name => "xxx",
:password => "xxx",
:enable_starttls_auto => true
}

# Print deprecation notices to the Rails logger
config.active_support.deprecation = :log

# Only use best-standards-support built into browsers
config.action_dispatch.best_standards_support = :builtin

# Do not compress assets
config.assets.compress = false

# Expands the lines which load the assets
config.assets.debug = true

Paperclip.options[:command_path] = "/usr/local/bin/"
end


nginx.conf

server {
listen 8088;
server_name localhost;
root /Users/suyejun/Documents/ruby/demo/public; # <--- be sure to point to 'public'!
passenger_enabled on;
}
