ruby-on-rails - Apache2 Passenger(谷歌计算引擎)通过 Ruby 版本捕获 SIGTERM？

Question

出于某种原因，Apache 似乎不喜欢我的 Rails 应用程序，该应用程序在 Google Compute Engine 上与 Phusion Passenger 一起运行(目前使用 WEBrick)。我在 Google 的“Click-to-Deploy”ruby 实例上运行它，该实例在 Debian 上运行。我还将 Ruby 更新到 2.2.2 并设置 rvm use global 2.2.2 .

我去rails s启动服务器，转到IP地址，然后得到一个可爱的500 Internal Error Apache 说我的服务器配置很困惑。如果我尝试去 <ip_address>:3000我没有收到服务器的响应。

配置文件(位于/etc/apache2/sites-available/

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /home/nick/qwestera
        RailsEnv production
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory "/home/nick/qwestera">
                Options FollowSymLinks
                Require all granted
        </Directory>

我认为的日志条目可能会给我一些见解:

[Fri Jul 31 18:55:23 2015] [notice] caught SIGTERM, shutting down
    [ 2015-07-31 18:55:24.5305 3807/7f317e333720 agents/Watchdog/Main.cpp:538 ]: Options: { 'analytics_log_user' => 'nobody', 'default_group' => 'nogroup', 'default_python' => 'python', 'default_ruby' => '/usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby', 'default_user' => 'nobody', 'log_level' => '0', 'max_pool_size' => '6', 'passenger_root' => '/usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.58', 'passenger_version' => '4.0.58', 'pool_idle_time' => '300', 'temp_dir' => '/tmp', 'union_station_gateway_address' => 'gateway.unionstationapp.com', 'union_station_gateway_port' => '443', 'user_switching' => 'true', 'web_server_passenger_version' => '4.0.58', 'web_server_pid' => '5755', 'web_server_type' => 'apache', 'web_server_worker_gid' => '33', 'web_server_worker_uid' => '33' }

具体:

'default_ruby' => '/usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby',

'passenger_root' => '/usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.58'

如果你注意到了，我说过我将 ruby​​ 更新为 2.2.2因为这就是我尝试运行的项目所使用的。然而，Apache 有 default_ruby和passenger_root目录包括ruby 2.1.1 。这会是问题吗？如果是这样，我该如何更改？

UPDATE:

正在删除Require all granted让我更近了一步(这一行仅对于大于 2.4 的 Apache 版本是必要的，我的是 2.2)。

现在我得到了一个乘客页面(我的 Rails 应用程序的 favicon.ico 出现了，耶!)，让我知道 Web application could not be started .

它向我显示了以下错误:

Your Ruby version is 2.1.1, but your Gemfile specified 2.2.2 (Bundler::RubyVersionMismatch)

  /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.58/helper-scripts/rack-preloader.rb:28:in `<main>'

分割: 我完全认为这是 Ruby 版本问题!现在，我如何让乘客知道在 2.2.2 的新 Ruby 目录中查找内容？

有趣且可能富有洞察力:

$ ruby --version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
$ ruby -version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
-e:1:in `<main>': undefined local variable or method `rsion' for main:Object (NameError)

ruby -version返回 NameError ，但是ruby --version才不是。搞什么？

UPDATE 2:

嗯，我已经更新了/etc/apache2/apache2.conf 以指向新目录。但是，我的 Rails 应用程序实际上并未运行。我只看到应用程序中所有文件和文件夹的索引。我如何告诉它开始？

Answer 1

通过使用rvm uninstall 2.1.1卸载旧版本的Ruby，使用rvm install 2.2.2重新安装新版本，然后使用passenger再次安装passenger来解决-安装-apache2-module。
