Capistrano 3: Connection refused - connect(2)

[R]

Hello guys,

I am trying to set up Capistrano 3 for my Rails 4 application, the setup is following:

deploy.rb

---

SSHKit.config.command_map[:rake] = "bundle exec rake"
# config valid only for Capistrano 3.1
lock '3.1.0'
set :application, 'myapp'
set :scm, :git set
set :repo_url, 'g...@bitbucket.org:username/repo.git'
set :stages, ["staging", "production"]
set :default_stage, "staging"
set :format, :pretty set
set :pty, true
set :keep_releases, 5
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Your restart mechanism here, for example:
# execute :touch, release_path.join('tmp/restart.txt')
end
end
after :publishing, :restart after
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
# within release_path do
# execute :rake, 'cache:clear'
# end
end
end

and in deploy/staging.rb:
role :app, %w{deployer@IP_ADDRESS}
role :web, %w{deployer@IP_ADDRESS}
role :db,  %w{deployer@IP_ADDRESS}
server "IP_ADDRESS", user: 'deployer', roles: %w{app web db}
set :deploy_to, "/home/deployer/apps/myapp-staging"
set :ssh_options, {
    forward_agent: false,
    auth_methods: %w(password),
    password: 'my_password',
    user: 'deployer',
}

When I run
cap staging deploy 

I get:
 INFO [f15d031b] Running /usr/bin/env mkdir -p /tmp/myapp/ on IP_ADDRESS
DEBUG 
DEBUG [f15d031b] Command: /usr/bin/env mkdir -p /tmp/myapp/
cap aborted!
Errno::ECONNREFUSED: Connection refused - connect(2) 

Why Capistrano can't deploy the app on the staging server?
Thank you in advance for every help.

Your staging server is unreachable.

But I can log in with the credentials through SSH, does it mean, that I miss something in the deploy.rb/staging.rb file?

[Lee Hambley]

​I'd guess so, but you took too much out of the logs for us to help.​

Ok, so I killed one afternoon because of not specifying the port number.

Thanks for pointing me out.
