`puma：restart'调用两次，但我只通过Capistrano在我的部署应用程序上调用它一次？

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

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 

代码，所以，当我跑“帽生产部署”一切工作顺利我的网站可以成功部署，但我之后得到的消息。

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。 那么我该如何解决这个问题呢？

谢谢！

Answer 1

我假设你使用的是capistrano3-puma宝石。在成功部署结束时，该宝石会自动为您重新启动。所以这是第一次调用重启任务。

此外，在您的deploy.rb中，您已经定义了自己的自定义重新启动任务，并调用它after :finishing。这是第二次调用的来源，因此也是警告。

“修理” 这个问题，删除冗余的任务：

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
