Question

我尝试使用 production.rb

使用Capistrano部署项目

app_path = "home/spree/spree"
app_name = "spree"
# Set environment to development unless something else is specified
env = ENV["RAILS_ENV"] || "development"

# See http://unicorn.bogomips.org/Unicorn/Configurator.html for complete documentation.
worker_processes 3

# listen on both a Unix domain socket and a TCP port, 
# we use a shorter backlog for quicker failover when busy
listen "#{app_path}/current/tmp/sockets/#{app_name}.socket", backlog: 64

# Preload our app for more speed
preload_app true

# nuke workers after 30 seconds instead of 60 seconds (the default)
timeout 30

#pid "#{app_path}/current/tmp/pids/unicorn.#{app_name}.pid"
pid "tmp/pids/unicorn.#{app_name}.pid"

# Production specific settings
if env == "production"
  # Help ensure your application will always spawn in the symlinked
  # "current" directory that Capistrano sets up.
  #working_directory "#{app_path}/current"
  working_directory ""

  # feel free to point this anywhere accessible on the filesystem user
  shared_path = "#{app_path}/shared"

  stderr_path "#{shared_path}/log/unicorn.stderr.log"
  stdout_path "#{shared_path}/log/unicorn.stdout.log"
end

before_fork do |server, worker|
  # the following is highly recomended for Rails + "preload_app true"
  # as there's no need for the master process to hold a connection
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.connection.disconnect!
  end

  # Before forking, kill the master process that belongs to the .oldbin PID.
  # This enables 0 downtime deploys.
  old_pid = "#{server.config[:pid]}.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end
end

after_fork do |server, worker|
  # the following is *required* for Rails + "preload_app true"
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
  end

  # if preload_app is true, then you may also want to check and
  # restart any other shared sockets/descriptors such as Memcached,
  # and Redis.  TokyoCabinet file handles are safe to reuse
  # between any number of forked children (assuming your kernel
  # correctly implements pread()/pwrite() system calls)
end

deploy.rb

# config valid only for Capistrano 3.1

namespace :deploy do

  desc 'Restart application'

    invoke  'unicorn:restart' 
    on roles(:app), in: :sequence, wait: 5 do

  after :publishing, :restart

  after :restart, :clear_cache do

      within release_path do
        execute :rake, 'cache:clear'
      end
    end
  end

end

的Gemfile

group :development do
  # Deploy
  gem 'capistrano',  '~> 3.1'
  gem 'capistrano-rails',   '~> 1.1', require: false
  gem 'capistrano-bundler', '~> 1.1', require: false
  gem 'capistrano-rvm',   '~> 0.1', require: false

end

group :production do
  gem 'unicorn', '~> 4.8.3'
  gem 'unicorn-rails'
  gem 'capistrano3-unicorn'
end

Capfile

# Load DSL and Setup Up Stages

# Includes default deployment tasks
require 'capistrano/deploy'

# Includes tasks from other gems included in your Gemfile

# For documentation on these, see for example:

require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

但是，当我运行 cap production deploy 时，我总是遇到此错误 - ＆gt; http://pastebin.com/wRAFxbz1

有人可以帮我解决错误。

Capistrano将current_path连接到release_path
