我的RoR应用程序在本地测试得很好。在使用rails server以及passenger start进行测试时，所有测试都会通过，并且应用会根据需要在本地运行。
不幸的是，当应用程序部署到AWS EB并委派了一个或多个AWS EC2实例时，实例的运行状况会立即恶化为“降级”。并且自动缩放/负载均衡器功能（如果已激活）尝试使用相同的结果启动更多实例。
访问Beanstalk环境的URL只会导致空白页面（空源代码）。我不知道该怎么做..我已经从下面的错误日志转储中找到了几行我认为可能很有见地但我无法从中获得解决方案：
2016/07/13 01:17:42 [error] 2880#0: *4 "/var/app/current/public/index.html" is not found (2: No such file or directory), client: 127.0.0.1, server: _, request: "HEAD / HTTP/1.1", host: "0.0.0.0"

非常感谢任何帮助！

memory. However your system only has 995 MB of total virtual memory (995 MB
RAM, 0 MB swap). It is recommended that you temporarily add more swap space
before proceeding. You can do it as follows:
sudo dd if=/dev/zero of=/swap bs=1M count=1024
sudo mkswap /swap
sudo swapon /swap
See also https://wiki.archlinux.org/index.php/Swap for more information about
the swap file on Linux.
If you cannot activate a swap file (e.g. because you're on OpenVZ, or if you
don't have root privileges) then you should install Phusion Passenger through
DEB/RPM packages. For more information, please refer to our installation
documentation:
https://www.phusionpassenger.com/library/install/standalone/
Press Ctrl-C to abort this installer (recommended).
Press Enter if you want to continue with installation anyway.
