在 Rails 3 应用程序中 cap:deploy 后，Resque 未启动

Question

我最近将 capistrano 添加到我的测试 rails 应用程序中以了解 capistrano 的工作原理。我可以使用它部署应用程序，但我的 resque 命令没有被执行。

它没有显示任何错误，但没有启动 resque worker。我什至通过登录服务器进行了检查。我尝试将 capistrano 中的后挂钩从 deploy:restart 更改为 deploy:published。

deploy.rb

lock '3.6.1'

set :application, 'test_app'
set :repo_url, 'sample_url.git'
set :resque_log_file, "log/resque.log"

set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system')

config/deploy/capistrano_test.rb

set :use_sudo, true

server 'ruby2', user: 'ubuntu', roles: %w{web app db}
set :ssh_options, { forward_agent: true }

set :branch, 'capistrano_test'
set :deploy_to, '/var/www/test_cap'

role :resque_worker, 'ruby2'

set :workers, { 
    ruby2: {"file_serve"=>1,"*" => 1,"tasks_queue"=>1,"sunspot"=>1} 
}

after "deploy:restart", "resque:restart"

require 'capistrano/rails/migrations'
require 'capistrano/rake'
require "capistrano-resque"

Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

resque:restart 正在调用，但没有任何反应。

Answer 1

我能够运行通过更改以下代码重新请求：

set :workers, { 
    ruby2: {"file_serve"=>1,"*" => 1,"tasks_queue"=>1,"sunspot"=>1} 
}

对此：

set :workers, { "file_serve"=>1,"*" => 1,"tasks_queue"=>1,"sunspot"=>1}

但是我还是不明白为什么之前的代码没有运行，正如文档中提到的那样。
