Ubuntu 12.10 Nginx Rails 3.2.13. Deploy in sub URI. Nothing happens!

Dear friends,
I followed the guide on

and successfully deployed two apps on the same web server, some months
ago.
Then when I upgraded to Rails 2.3.13.rc1 everything seems to be OK, but
when I visit my app with the browser all that I get is the Welcome page
from Nginx.
Here is my nginx.conf:

worker_processes 4;
http {
passenger_root
/home/luis/.rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19;
passenger_ruby /home/luis/.rvm/wrappers/ruby-1.9.3-p392/ruby;

server {
listen 80;
server_name domain.com;
root /home/lacy/public_html;
passenger_enabled on;
passenger_base_uri /myapp1;
location / {
root html;
index index.html index.htm; }
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html; }
}

Here is my deploy.rb:

require “bundler/capistrano”
require “rvm/capistrano”
set :rvm_ruby_string, :local

set :domain, ‘www.myapp1.domain.com
set :application, “myapp1”
set :repository, “[email protected]:xxxxxxxx/myapp1.git”
set :branch, “master”

set :scm, “git”
set :user, “myapp1”
set :deploy_to, “/home/myapp1/apps/#{application}”
set :deploy_via, :remote_cache
set :copy_strategy, :export

set :use_sudo, false
set :keep_releases, 3

role :web, ‘my IP’
role :app, ‘my IP’
role :db, ‘my IP’, :primary => true

set :port, 22

after ‘deploy:update_code’ do
run “cd #{release_path}; RAILS_ENV=production rake assets:precompile”
end

If you are using Passenger mod_rails uncomment this:

namespace :deploy do
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
run “#{try_sudo} touch #{File.join(current_path,‘tmp’,‘restart.txt’)}”
end
end

Curiously /opt/nginx/logs/error.log doesn’t report anything.
I am fighting with this problem during many days without any solution.
I’m
very tired and under hard pressure from my client,
Does anybody have a hint, where to look for my mistake?
Thanks in advance!

Try to create database on server $> rake db:create RAILS_ENV=production

replace this:
root /home/lacy/public_html;
on this
root /home/lacy/your-app-name/current/public;

Remove this:
location / {
root html;
index index.html index.htm; }
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html; }

Dont use ‘www’
set :domain, ‘www.myapp1.domain.com

Be sure you’ve added ‘domain.com’ and ‘myapp1.domain.com’ in your
/etc/hosts file

Make the same
set :deploy_to, " /home/lacy/your-app-name"
and in your nginx config file
root /home/lacy/your-app-name/current/public;

After changing your nginx.cong file restart nginx
$> sudo service nginx stop
$> sudo service nginx start
(or $> sudo service nginx reload && sudo service nginx restart)
