Capistrano：链接的文件database.yml不存在于my.server.ipadress上

问题描述

  DEBUG [605f198a]完成后，我尝试通过capistrano部署我的应用程序到我的服务器在0.084秒内，退出状态1（失败）。 
错误链接的文件/home/deploy/myrailsapp/shared/config/database.yml不存在于xx.xxx.xx.xxx 
（仅限于引入的任务）
帽已中止！ 
 SSHKit :: Runner :: ExecuteError：执行为[email protected]时出现异常：exit 
 
 SystemExit：exit 
 
任务：TOP = > deploy：check：linked_files 
（通过运行任务--trace查看完整跟踪）
部署失败并显示错误：执行为[email protected]时出现异常：exit 
  

我的deploy.rb是：

  set：deploy_to，'/ home / deploy / myrailsapp'
 set：linked_files，％w {config / database.yml} 
 set：linked_dirs，％w {bin log tmp / pids tmp / cache tmp / sockets vendor / bundle public / system} 
 
 
 
命名空间：deploy do 
 desc'重新启动应用程序'
任务：重新启动$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ 
 $ b end 
 after：publishing，'deploy：restart'
 after：finish，'deploy：cleanup'
 end 
 
 
命名空间：deploy do 
 after：restart，：clear_cache do 
 on roles（：web），in：：groups，limit：3，wait：10 do 
＃这里我们可以做任何事情，如：
＃内se_path do 
＃execute：rake，'cache：clear'
＃end 
 end 
 end 
 end

我试过这个tut ，这是我第一次使用capistrano。
解决方案
只需创建 /home/deploy/myrailsapp/shared/config/database.yml 文件手动调整。 
 
 
 
 Capistrano不会立即创建（或管理）配置文件。所以，你应该手动或自动使用自己的 Capistrano 脚本， Puppet ， Chef ，可复制工具。 
 
after i try to deploy my app via capistrano to my server i get this error message:
DEBUG [605f198a] Finished in 0.084 seconds with exit status 1 (failed).
ERROR linked file /home/deploy/myrailsapp/shared/config/database.yml does not exist on xx.xxx.xx.xxx

Tasks: TOP => deploy:check:linked_files
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as [email protected]: exit
my deploy.rb is:
set :deploy_to, '/home/deploy/myrailsapp'
set :linked_files, %w{config/database.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}



namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute :touch, release_path.join('tmp/restart.txt')
    end
  end
  after :publishing, 'deploy:restart'
  after :finishing, 'deploy:cleanup'
end


namespace :deploy do
  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end
end
i tried this tut https://www.gorails.com/deploy/ubuntu/14.04, this is my first try with capistrano.
 解决方案 
Just create /home/deploy/myrailsapp/shared/config/database.yml file manually and adjust it. 
Capistrano doesn't create (or manage) configuration file out of the box. So, you should do it manually or automate use own Capistrano scripts, Puppet, Chef, Ansible tools.
