Question

我有一个capistrano部署脚本可以在我的Windows本地计算机上运行，但是mac上的同事正在遇到部署错误。它实际上只是他的笔记本电脑，因为它也适用于其他的Mac，所以我想知道是否有一些需要清除的capistrano缓存？错误是......

* Compressing /var/folders/kv/g4k3rk815sd14948vzf1lhg40000gn/T/20131203013325 to /var/folders/kv/g4k3rk815sd14948vzf1lhg40000gn/T/20131203013325.tar.gz

*** [deploy:update_code] rolling back
 ** [deploy:update_code] exception while rolling back: Capistrano::NoMatchingServersError, `deploy:update_code' is only run for servers matching {:except=>{:no_release=>true}}, but no servers matched `deploy:update_code' is only run for servers matching {:except=>{:no_release=>true}}, but no servers matched

我的deploy.rb（重要部分）如下......

set :application, "app"

task :prod do 
  role :app, "10.1.40.123"
  role :web, "10.1.40.123"
  role :db,  "10.1.40.123", :primary => true
  set :user, "root"
  set :password, "password"
  set :rails_env, "production"
  set :use_sudo, false
  load 'deploy/assets' # this line runs rake assets precompile
  set :os, 'ubuntu'
  default_environment["LD_LIBRARY_PATH"] = '/opt/oracle/instantclient_12_1'
end 
set :repository, "ssh://gituser@example.com/opt/git/hub/app.git"
set :deploy_to, "/srv/www/#{application}"
set :deploy_via, :copy
set :keep_releases, 5

set :scm, "git"
set :branch, "master"

after 'deploy:update_code', 'deploy:symlink_shared', "deploy:migrate","deploy:restart"

他可以使用capistrano部署其他应用，我们使用的是capistrano 2.

似乎您尝试使用自定义任务而不是使用multistage extension部署到多个阶段。这样，当您运行cap prod时，您实际上并未部署，并且在运行cap deploy时您没有设置角色，这会导致错误。因此，解决方案是将deploy.rb重写为以下内容：

set :stages, %w(prod staging)
set :default_stage, "staging"
require 'capistrano/ext/multistage'

set :application, "app"
set :repository, "ssh://gituser@example.com/opt/git/hub/app.git"
set :deploy_to, "/srv/www/#{application}"
set :deploy_via, :copy
set :keep_releases, 5

set :scm, "git"
set :branch, "master"

after 'deploy:update_code', 'deploy:symlink_shared', "deploy:migrate","deploy:restart"

然后，在您的config/deploy/prod.rb中，您应该与您的产品相关设置：

role :app, "10.1.40.123"
role :web, "10.1.40.123"
role :db,  "10.1.40.123", :primary => true
set :user, "root"
set :password, "password"
set :rails_env, "production"
set :use_sudo, false
load 'deploy/assets' # this line runs rake assets precompile
set :os, 'ubuntu'
default_environment["LD_LIBRARY_PATH"] = '/opt/oracle/instantclient_12_1'

这样，如果您将cap prod deploy更改为cap deploy，您就可以使用set :default_stage, "staging"（或set :default_stage, "prod"}部署到制作中。
