Question

我正在运行一个rails应用程序，其中angularjs作为我的前端。

我刚把它推到了制作阶段，但是我遇到了一个非常奇怪的问题。

我在Amazon EC2（Ubuntu 64位机器）上使用了瘦和Nginx服务器。

虽然这样做但我得到的问题是瘦服务器在给定的时间（1-5分钟）后停止。这是在现场网站上发生的。

我生成的日志文件如下： -

我在nginx上运行4台瘦服务器。我试了很多东西，但没有什么能帮到我。

任何帮助将不胜感激。

更新： -

我已经将应用程序移动到Amazon EC2上的32位Ubuntu服务器，它似乎在那里正常工作。

我似乎不明白这个问题，但必须在几天内将应用程序放回64位服务器上。

我没有看到应用程序的任何问题，但不知道为什么它在64位服务器上崩溃。这与瘦服务器或宝石的任何问题有关吗？

请帮我解决这个问题

Answer 1

试试这个

瘦-e production -d start

-e是针对环境的 -d允许它在后台运行当你不使用-d时，它需要一个开放的终端来继续运行

瘦服务器无法在Amazon Ec2上的生产模式（实时）上运行
