哪些步骤将重现该问题？

  1. 在 amazon ec2 上用橡胶设置导轨，乘客 4.0.23。
  2. 部署
  3. 检查 apache 日志

什么是预期的输出？我看到了什么？

我希望有一个可用的 Rails 网站。我得到页面无法显示。

Phusion 乘客版本、轨道、操作系统

亚马逊 EC2 上的 Rails 4.0.0 乘客 4.0.23 操作系统 Ubuntu 12.04

下面的附加信息。

我使用橡胶宝石来设置亚马逊 ec2 实例。一切都很好。并且部署成功。但我无法实时看到我的应用程序。我检查了 apache 日志，那里有乘客错误。

更新

按照 Hongli 的建议，我将 MaxPoolSize 减少到 5。

现在，我在错误日志中得到了这个。

我认为这意味着服务器设置成功。但我仍然无法在线浏览我的网站。（我已经检查了安全组，它们允许 0.0.0.0 到端口 80/443。mysql 也是如此。Rails/log/production.log是空的。

Phusion 乘客作者在这里。

在日志中注意到这一点了吗？

 Cannot allocate memory - fork(2) (Errno::ENOMEM)

这意味着您的系统内存不足。

并注意到这一点？

 An error occurred while starting the web application.
 It exited before signalling successful startup back to Phusion Passenger.

这意味着Passenger 尝试为您的Web 应用程序生成一个进程，但由于上述错误（内存不足）而失败。

您可以做 3 件事：

  • 升级你的记忆。
  • 升级您的交换空间。
  • 调整您的乘客设置，使其不会启动那么多进程。这可以节省您的内存。查看乘客手册以了解调整选项。

我会建议你使用Passenger+Nginx Modul。以下是安装 Ruby、rails 和配置乘客的步骤。

  1. 安装所需的库

    sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs

  2. 下载并安装 Ruby 1.9.3

    sudo apt-get update
sudo apt-get install ruby1.9.3

    或者

    wget ftp://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p195.tar.gz
apt-get install wget build-eruby+rails+mysql+passenger+ngnixssential make     
cd ruby-2.0.0
$  ./configure
$   make
$   sudo make install

3.下载 RUBY GEM：标准的 RUBY PACKAGE MANAGER 不需要安装，在安装 ruby​​ 的时候就已经安装好了

4.安装导轨

sudo apt-get install ruby-dev
sudo gem install rails

8.乘客安装

gem install passenger

9.安装NGINX

sudo apt-get install libcurl4-openssl-dev or libcurl4-gnutls-dev
sudo apt-get install libssl-dev
sudo passenger-install-nginx-module

10.启动NGINX

    sudo service nginx start
