我跟随Ryan的屏幕录像并部署到VPS。 所以我使用Unicorn + nginx + github + Ubuntu 12.04 LTS + capistrano。 另外我用i18n来翻译应用程序。
我也想注意到，我使用Carriarewave进行图片上传。 Carriarewave在本地保存VPS上的图片。 当我上传的图像，它的作品很棒，上传的图片出现。
但每当我部署新的更改到服务器，然后所有我的照片被打破。 这真是太棒了。 我尝试手动重新启动nginx：
sudo service nginx restart 而我试图重新启动麒麟：
/etc/init.d/unicorn_Chirch_app restart
它也没有帮助。
当我尝试打开我的破碎的页面手动它说：
The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved.
当我尝试在控制台中查找图片时：
> Photo.all > => [#<Photo id: 3, description: nil, created_at: "2013-01-21 11:14:01", updated_at: "2013-01-21 11:14:01", image: "1320700703588.jpg">, #<Photo id: 4, description: nil, created_at: "2013-01-21 11:14:01", updated_at: "2013-01-21 11:14:01", image: "Seasonscape_by_alexiuss.jpg">, #<Photo id: 5, description: nil, created_at: "2013-01-21 11:30:30", updated_at: "2013-01-21 11:30:30", image: "Seasonscape_by_alexiuss.jpg">]
据我了解，他们应该存在。

好的，我找到了解决方案。 出现这个问题是因为我没有更改默认文件夹来保存图像。 您可以在public/uploads找到您的默认文件夹。 这意味着每个cap deploy将创建一个不包含旧文件的新的空文件夹。
要解决这个问题，你应该创建另一个不在你的应用程序中的文件夹。 我选择最简单的方法。 我创建了symlinlk。
我的步骤：
1）在你的服务器上转到你的应用程序的共享文件夹（它通过capistrano自动生成）。 然后创建您的文件夹，以保持新的图像：
$ mkdir uploads
2）为创建的文件夹提供必要的权限：
$ sudo chmod 775 uploads
3）在config / deploy.rb的本地机器上添加：
task :symlink_config, roles: :app do ... run "ln -nfs #{shared_path}/uploads #{release_path}/public/uploads" end
4）然后推git和部署：
$ git push $ cap deploy:symlink $ cap deploy
现在一切正常。
好的！ 我已经延长了你的Capistrano配方。
