Apache2 Passenger（Google Compute Engine）在 Ruby 版本上捕获 SIGTERM？
Apache2 Passenger (Google Compute Engine) catching SIGTERM over Ruby Version?
出于某种原因，Apache 似乎不喜欢我的 Rails 应用程序，运行 在 Google Compute Engine 上使用 Phusion Passenger（目前使用 WEBrick）。我在 Google 的 "Click-to-Deploy" ruby 实例上 运行 将其安装在 Debian 上 运行。我还将 Ruby 更新为 2.2.2 并设置了 rvm use global 2.2.2.
我去 rails s 并启动服务器，转到 IP 地址，然后从 Apache 得到一个可爱的 500 Internal Error 说我的服务器配置一团糟。如果我尝试去 <ip_address>:3000 我没有得到服务器的响应。

我认为 的日志条目可能会给我一些见解：

具体来说：
'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'
如果您注意到了，我说我将 ruby 更新为 2.2.2，因为这就是我正在尝试 运行 使用的项目。但是，Apache 有 default_ruby 和 passenger_root 目录，其中包括 ruby 2.1.1。这会是问题吗？如果是这样，我该如何更改？
UPDATE:
删除 Require all granted 让我更近了一步（此行仅适用于大于 2.4 的 Apache 版本，我的版本是 2.2）。
现在我得到了一个乘客页面（显示了我的 rails 应用程序的 favicon.ico，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)

细分：
我完全说是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？
有趣且可能有见地：
$ 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 -versionreturns一个NameError，但是ruby --version没有。什么鬼？
UPDATE 2:
好吧，我已经更新了 /etc/apache2/apache2.conf 以指向新目录。但是，我的 rails 应用程序实际上并不是 运行ning。我只看到我的应用程序中所有文件和文件夹的索引。我如何让它开始？
解决方法是使用 rvm uninstall 2.1.1 卸载旧版本 Ruby，使用 rvm install 2.2.2 重新安装新版本，然后使用 passenger-install-apache2-module.
再次安装 passenger
出于某种原因，Apache 似乎不喜欢我的 Rails 应用程序，运行 在 Google Compute Engine 上使用 Phusion Passenger（目前使用 WEBrick）。我在 Google 的 "Click-to-Deploy" ruby 实例上 运行 将其安装在 Debian 上 运行。我还将 Ruby 更新为 2.2.2 并设置了 rvm use global 2.2.2.

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' }
具体来说：
'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'
如果您注意到了，我说我将 ruby 更新为 2.2.2，因为这就是我正在尝试 运行 使用的项目。但是，Apache 有 default_ruby 和 passenger_root 目录，其中包括 ruby 2.1.1。这会是问题吗？如果是这样，我该如何更改？
UPDATE:
删除 Require all granted 让我更近了一步（此行仅适用于大于 2.4 的 Apache 版本，我的版本是 2.2）。
现在我得到了一个乘客页面（显示了我的 rails 应用程序的 favicon.ico，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)

细分： 我完全说是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？
有趣且可能有见地：
$ 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 -versionreturns一个NameError，但是ruby --version没有。什么鬼？
UPDATE 2:
好吧，我已经更新了 /etc/apache2/apache2.conf 以指向新目录。但是，我的 rails 应用程序实际上并不是 运行ning。我只看到我的应用程序中所有文件和文件夹的索引。我如何让它开始？
解决方法是使用 rvm uninstall 2.1.1 卸载旧版本 Ruby，使用 rvm install 2.2.2 重新安装新版本，然后使用 passenger-install-apache2-module.
