我跟随Ryan 的截屏视频并部署到 VPS。所以我使用 Unicorn + nginx + github + Ubuntu 12.04 LTS + capistrano。我也使用 i18n 来翻译应用程序。
我还想注意我使用Carriarewave进行图片上传。Carriarewave 将图片保存在本地 VPS 上。当我上传图片时效果很好,上传的图片就会出现。
但是每次当我将新的更改部署到服务器时,我的所有图片都会损坏。实在是太可怕了。我尝试手动重启nginx:
sudo service nginx restart
我试图重新启动独角兽:
/etc/init.d/unicorn_Chirch_app restart
它也没有帮助。
当我尝试手动打开损坏的页面时,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,它们应该存在。
