可能是一些东西，但是在Capistrano 3中，
deploy:colddeploy:setup\u configdeployexecutenamespace :logs do
desc "tail rails logs"
task :tail_rails do
on roles(:app) do
execute "tail -f #{shared_path}/log/#{fetch(:rails_env)}.log"
end
end
end
task :setup_config, roles: :app do
# some stuff
end
task :setup_config do
on roles(:app) do
#some stuff
end
end
看起来您的Cap 2配置在很大程度上是基于Railscast的。我也是，我最近经历了将所有使用它的应用程序迁移到新的Cap 3应用程序的过程。我已经记录了我最终使用的方法，包括代码。可能是一些东西，但是在Capistrano 3中，
