ruby-on-rails - `puma:restart'调用两次，但我只能通过Capistrano在我的部署应用程序上调用一次？

Question

我试图通过Capistrano将Rails应用程序部署到服务器。
这是我在deploy.rb上的代码

set :repo_url,        'git@bitbucket.org:varisdaOfficial/insurance_site.git'
set :application,     'insurance_code'
set :user,            'deploy'
set :puma_threads,    [4, 16]
set :puma_workers,    0

set :pty,             true
set :use_sudo,        false
set :stage,           :production
set :deploy_via,      :remote_cache
set :deploy_to,       "/home/#{fetch(:user)}/apps/#{fetch(:application)}"
set :puma_bind,       "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
set :puma_state,      "#{shared_path}/tmp/pids/puma.state"
set :puma_pid,        "#{shared_path}/tmp/pids/puma.pid"
set :puma_access_log, "#{release_path}/log/puma.error.log"
set :puma_error_log,  "#{release_path}/log/puma.access.log"
set :ssh_options,     { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/id_rsa.pub) }
set :puma_preload_app, true
set :puma_worker_timeout, nil
set :puma_init_active_record, true  # Change to false when not using ActiveRecord
set :linked_dirs, %w(public/uploads)

namespace :puma do
  desc 'Create Directories for Puma Pids and Socket'
  task :make_dirs do
    on roles(:app) do
      execute "mkdir #{shared_path}/tmp/sockets -p"
      execute "mkdir #{shared_path}/tmp/pids -p"
    end
  end

  before :start, :make_dirs
end

namespace :deploy do
  desc "Make sure local git is in sync with remote."
  task :check_revision do
    on roles(:app) do
      unless `git rev-parse HEAD` == `git rev-parse origin/master`
        puts "WARNING: HEAD is not the same as origin/master"
        puts "Run `git push` to sync changes."
        exit
      end
    end
  end

  desc 'Initial Deploy'
  task :initial do
    on roles(:app) do
      before 'deploy:restart', 'puma:start'
      invoke 'deploy'
    end
  end

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      invoke 'puma:restart'
    end
  end

  desc 'clear temp cache'
  task :clear_cache do
    on roles(:app) , in: :sequence, wait: 1 do
      execute "rm -rf #{shared_path}/tmp/cache/[^.]*"

    end
  end

  before :starting,     :check_revision
  after  :finishing,    :compile_assets
  after  :finishing,    :cleanup
  after  :finishing,    :clear_cache
  after  :finishing,    :restart
end

因此，当我运行“帽子生产部署”时，一切都可以顺利进行，我的站点可以成功部署，但是之后我收到了一条消息。

Capistrano tasks may only be invoked once. Since task `puma:restart' was previously invoked, 
invoke("puma:restart") at/Users/manjarb/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/capistrano3-puma-1.2.1/lib/capistrano/tasks/puma.rake:134 will be skipped.
If you really meant to run this task again, first call Rake::Task["puma:restart"].reenable
THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF CAPISTRANO. Please join the conversation here if this affects you.

我只调用一次重启任务。
那么我该如何解决此消息？

谢谢!

Answer 1

我假设您正在使用capistrano3-puma gem 。成功部署结束后，该gem会自动为您重新启动puma。因此，这是第一次调用重新启动任务。

此外，在deploy.rb中，您已经定义了自己的自定义重启任务，并且正在调用after :finishing。这是第二次调用的源头，因此也是警告的源头。

要“解决”此问题，请删除冗余任务:

desc 'Restart application'
task :restart do
  on roles(:app), in: :sequence, wait: 5 do
    invoke 'puma:restart'
  end
end

并删除此:

after  :finishing,    :restart
