Capistrano的 - 不能部署我的database.yml

Question

当我尝试部署我与Capistrano的应用程序，我会得到这个错误：

failed: "sh -c 'cp /var/www/my_app/releases/20120313115055/config/database.staging.yml /var/www/my_app/releases/20120313115055/config/database.yml'" on IP_ADDR

我的database.yml即空，database.staging .yml：

production: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: my_db 
    pool: 15 
    username: my_user_name 
    password: my_pass 
    host: localhost 

在 /confing

/部署是文件的 “生产”， “分期”

我在这里错过了什么/我应该在哪里寻找失败？服务器上的数据库凭据应该是正确的。

编辑 - 这里是我的部署

end 

问题：

cp: cannot stat `/var/www/my_app/releases/20120313144907/config/database.staging.yml': No such file or directory 

Answer 1

我不知道如何解决你的问题。它看起来像database.staging.yml没有被部署，所以没有什么可以复制。

但我认为这有一个更好的工作流程。像设置和数据库配置之类的事情通常不会在部署之间发生变化，所以这些事情可以在所有Capistrano版本的共享文件夹中进行。通常情况下，你不希望你的database.yml在你的repo中，因为它是敏感信息。您可以通过在您的.gitignore中排除config/database.yml来满足这两个要求。

这需要您在服务器上设置一次。您需要创建一个database.yml在your_app_path/shared/config。共享是当前和发布的兄弟。

您的deploy.rb应该有一个任务，将新部署的版本database.yml符号链接到共享目录中的on。就像这样：

before "deploy:assets:precompile" do 
    run ["ln -nfs #{shared_path}/config/settings.yml #{release_path}/config/settings.yml", 
     "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml", 
     "ln -fs #{shared_path}/uploads #{release_path}/uploads" 
    ].join(" && ") 
end 

这意味着你的回购不包含任何database.yml文件。因为他们可能已经在你的回购。你必须要git rm他们，提交。将它们添加到.gitignore并确认。

Answer 2

如果您不需要时预编译，然后“参考应用程序对象或方法”（1），你可能会在config/application.rb

Answer 3

在Capistrano的3设置config.assets.initialize_on_precompile到false OK，链接文件是内置。约翰的回答很简单：

• 在shared/文件夹中创建config/database.yml

• 在config/deploy.rb使用此行

  set :linked_files, fetch(:linked_files, []).push('config/database.yml') 
  

这不会有什么约翰说。
