ruby-on-rails - 瘦服务器无法在 Amazon Ec2 上的生产模式(实时)下工作

Question

我正在运行一个以 angularjs 作为前端的 rails 应用程序。

我刚刚将其投入生产，但是我遇到了一个非常奇怪的问题。

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

这样做时，我遇到的问题是瘦服务器在给定的时间(1-5 分钟)后停止。这发生在现场。

我生成的日志文件如下:-

>> Maximum connections set to 1024
>> Listening on 0.0.0.0:3000, CTRL+C to stop

我在 nginx 上运行 4 台瘦服务器。我尝试了很多东西，但没有任何帮助。

任何帮助将不胜感激。

更新:-

我已将应用程序移至 Amazon EC2 上的 32 位 Ubuntu 服务器，它似乎运行良好。

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。

我没有看到该应用程序有任何问题，但不知道为什么它在 64 位服务器上崩溃。是与瘦服务器有关还是与 gems 有任何问题？

这个你能帮我吗

Answer 1

尝试这个

瘦 -e 生产 -d 开始

-e 代表环境
-d 允许它在后台运行
当您不使用 -d 时，它需要一个打开的终端才能继续运行
