瘦服务器不工作的生产方式（现场）在Amazon EC2 [英] Thin server not working on Production mode(live) on Amazon Ec2

问题描述

我正在运行Rails应用程序与angularjs作为我的前端。

I am running a rails app with angularjs as my front end.

我刚刚把它推到生产，但是我得到一个非常奇怪的问题。

I have just pushed it to production, however I am getting a very strange issue.

我已经使用既轻薄又Nginx的服务器，因为它是在Amazon EC2（Ubuntu的64位机）。

I have used both thin and Nginx server as it is on Amazon EC2(Ubuntu 64 bit machine).

虽然这样的问题，我得到的是在给定时间（1-5分钟）后，瘦服务器正在停止。这是发生在一个直播现场。

While doing so the issue I am getting is the thin server is stopping after a given amount of time (1-5 mins). This is happening on a live site.

我生成的日志文件如下： -

The log file I am generating is the following:-

>> Thin web server (v1.5.1 codename Straight Razor)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:3000, CTRL+C to stop

下面是我的Gemfile code：

Below is my gemfile code:

source 'https://rubygems.org'

gem 'rails', '3.2.8'
gem 'rake' , '10.1.0'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'


gem 'json','1.8.0'

# in production environments by default.

我运行4台服务器上薄的nginx。我尝试了很多东西，但没有什么帮助了我。

I am running 4 servers of thin on nginx. I tried out many things but nothing is helping me.

任何帮助将AP preciated。

Any help will be appreciated.

更新： -

我提出申请，以32bit的Ubuntu的服务器在Amazon EC2上，它似乎是工作的罚款那里。

I have moved the application to 32bit Ubuntu server on Amazon EC2 and it seems to be working fine out there.

我似乎不明白这个问题，但必须把应用程序恢复64位服务器上几天。

I don't seem to understand the issue but have to put the application back on 64bit server in a couple of days.

我看不出与应用程序的任何问题，但不知道为何导致崩溃的64位服务器上。难道是与瘦服务器或宝石的任何问题？

I don't see any issue with the application but don't know why it is crashing on 64bit server. Is it something to do with thin server or any issue with the gems ?

请帮我出这个
