Capistrano Trouble From Git - ruby-on-rails

I am new to using git and Capistrano. I have setup everything else on my server and pushed my app onto a git repo (http://github.com/tnederlof/daily-trailer). When I go to run cap deploy:cold everything seems to be working until it tries to rake the db. Below is what I get when I run it, this is the last bunch of information I recieve and where the error occurs:
* executing "cd /var/www/dailytrailer.net/releases/20100205052047; rake RAILS_ENV=production db:migrate"

Can someone please help me figure out what script/spin is all about?
Thank you!

Do you know what you're trying to use for an app server? If it's Passenger, then you've got something screwed up in your deploy.rb. (Post that file if you want more help debugging this.) If it's mongrel, then this should be helpful.

I need some help. Its a multi rails app server. Please ask any more info if you need. I have also replaced site and github url with .... because of site security.
There is no thin process running on your server, that's why you're getting the Can't stop process, no PID found error. I suggest starting thin manually so your deploy script can then successfully restart it.

capistrano deployment unable to bundle install gem with no internet connection

This is box-specific deploy script myhostname.rb:
server "myhostname", :app, :web, :db, :primary => true
set :deploy_to, "/opt/web/var/myapp"
set :rails_env, "customertest"
set :branch, "staging"
Now the remote box does not have access to internet, but I have all my gems stored under vendor/cache. So it should pick up from there.(vendor/cache has nokigiri under /myapp/current/vendor/cache on remote server)
When i run
cap deploy servername
, i get the following error:
** [out :: myhost] An error occurred while installing nokogiri (1.5.9), and Bundler cannot
** [out :: myhost] continue.
** [out :: myhost] Make sure that `gem install nokogiri -v '1.5.9'` succeeds before bundling.
My remote box where the code is supposed to be deployed has the following folders set up:
/opt/web/var/myapp
/opt/web/var/myapp/current(where all the code is cloned currently)
/opt/web/var/myapp/releases
/opt/web/var/myapp/shared
I am not sure how it i supposed to pick up and install the gem.
This quote from bundler docs might be relevant (emphasis mine):
http://bundler.io/v1.9/bundle_package.html
By default, if you simply run bundle install after running bundle package, Bundler will still connect to rubygems.org to check whether a platform-specific gem exists for any of the gems in vendor/cache.
This behavior can be avoided by instead running bundle install --local. Note that this requires you to have the correctly platformed version for all of your gems already cached. The easiest way to achieve this is to run bundle package on an identical machine and then check in those vendored gems.
So, in short, you need to pass the --local flag when running bundler in the production server to avoid connecting to rubygems altogether.
The solution for use with capistrano is to set this variable in you deploy.rb file:
# deployment and quiet are used by default, we add the local flag
set :bundle_flags, "--deployment --quiet --local"

in my production.rb I have

load 'deploy'

load 'deploy/assets'
Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy' # remove this line to skip loading any of the default tasks
local precompile with "bundle exec rake assets:precompile RAILS_ENV=production --trace" executes without any errors.
Where is my mistake? Hot to debug it? Or maybe somewhere is some log file for capistano in which a can look for more details?
I find an answer by my own
delete "load 'deploy/assets'" from capfile, and run
cap deploy:cold
this will work without an error, but only on initial deploy. Then as usual "sudo service nginx restart" on server, and add back deleted snippet.
And BAMM!! It works :)
You are out of RAM by the sounds of it, this question and answer helped me out - I increased the swap on digital ocean server and everything worked fine: deploy with capistrano failing
For anyone who face the same problem and Andrey answer don't work stop the server "sudo service nginx stop" then cap deploy and then start the server again "sudo service nginx start". It worked for me.

Problems with sudo when deploying RVM with Capistrano

I would like to use Capistrano to deploy my app in my server
I have the deploy.rb file with the following content:
set :user, "deploy"
set :use_sudo, true
set :deploy_to, "/webapps/#{application}"
#set :deploy_via, :remote_cache #Using this option avoids to do a full repository clone
#RVM
set :rvm_type, :system #System Wide installation
set :rvm_ruby_string, 'ree#K2'
set :rvm_install_shell, :bash
before 'deploy:setup','rvm:install_rvm'
before 'deploy:setup', 'rvm:install_ruby'
# if you're still using the script/reaper helper you will need
# these http://github.com/rails/irs_process_scripts
# 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 "touch #{File.join(current_path,'tmp','restart.txt')}"
end
end
Everything works fine when i set the root user, installs RVM (system-wide installation) and even a Ruby Enterprise, but when I run 'cap deploy:setup' setting the use_sudo option and deploy user, get this:
$ cap deploy:setup
* executing `deploy:setup'
triggering before callbacks for `deploy:setup'

What I have to do to make this work? Do I have to adjust some settings in sudoers file?
please test with 1.1.0:
gem install rvm-capistrano

Any suggestions about the error? Thanks.
Get cap to connect and tell you where bundle is installed
cap invoke COMMAND='which bundle'
If the bundle command is not found, your PATH is not set correctly. You might need to PermitUserEnvironment in the sshd running on that host. Then you can set the path manually in the deploy user's .ssh/environment file.
Is bundler installed on the remote machine?
Somewhere in your log it says:
Could not find bundler (>= 0)
The problem may be that you need to create the bundler wrapper. You can do that this way(in your deploy.rb, for example)
require "rvm/capistrano" # http://beginrescueend.com/integration/capistrano/
# rvm-capistrano settings
set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"")
namespace :rvm do
task :create_bundle_wrapper, roles: :app do
run "rvm wrapper #{rvm_ruby_string} bundle bundle"
end
end
