Deploy a rails project with capistrano - ruby-on-rails

Question

I want to deploy my project with capistrano. Here is my settings file:
deploy.rb
require "capistrano/ext/multistage"
require "capistrano_colors"
require "bundler/capistrano"
require "rvm/capistrano" # Load RVM"s capistrano plugin.
set :application, "project"
set :copy_exclude, %w(.git .gitignore doc features log spec test tmp Capfile)
#set :shared_children, shared_children + %w(public/uploads)
set :use_sudo, false
set :user, "app"
set :stages, %w(staging production)
namespace :deploy do
task :start, roles: :app, except: { no_release: true } do
run "cd #{current_path} && bundle exec unicorn_rails -c config/unicorn.rb -E #{rails_env} -D"
end
task :stop, roles: :app, except: { no_release: true } do
run "kill -KILL -s QUIT `cat #{shared_path}/pids/unicorn.pid`"
end
task :restart, roles: :app, except: { no_release: true } do
stop
start
end
end
def confirm
puts "\n\e[0;36m#{stage}\e[0m\e[0;31m Do you really deploy? (yes/no) \e[0m\n"
proceed = STDIN.gets rescue nil
exit unless proceed.chomp! == "yes"
end
For the multistage, I have created two files (one by environment):
deploy/production.rb
server "myserver.net", :app, :web, :db, primary: true
set :rails_env, "production"
set :rvm_type, :user
set :rvm_ruby_string, "ruby-2.0.0-p0"
set :scm, :git
set :repository, 'ssh://xxxx#11.111.111.111:54333/~/git-workspace/myproject.git'
set :deploy_via, :remote_cache
confirm
and almost the same for the staging one.
( As you have guessed, I have changed project, server name and port number for security purposes)
I first executed :
bundle exe cap production deploy:check
then :
bundle exe cap production deploy:setup
without any problem, when calling the deploy command (bundle exe cap production deploy), i get the below message :
xxxx-no-MacBook-Air:myproject xxxx$ bundle exe cap deploy

I have generated keys (in my local environment) and put the public one in the authorized_keys file (server side).

You seem to have taken a lot of the right steps, so now with this kind of error, you should test the permissions directly:
Ensure that you can ssh from your development machine (where you're running capistrano) to the deployment server as that user. (E.g., that might be something along the lines of ssh deploy#myserver.com.
Once you've made sure that works, then while logged in on the server, as the deployment user, try connecting to the repository server. E.g., something like ssh -T git#github.com as described here.
99% of the time, if you can do these two things successfully, there will be no permissions problems.
