Ruby on rails 未能启动cap v3 rails 4乘客部署Web应用程序，因为找不到文件

当我们部署到我们的服务器时，一切都部署得很好，但是我们马上就会收到错误“gemfilenotfound”。起初我以为这是nginx没有启动，但是如果我重新启动这个盒子，错误就会消失，应用程序也会正常工作。我们正在试图确定为什么会发生这种情况，以及如何解决它。到目前为止，我还不知道从哪里开始，而且我对“谷歌”的研究似乎没有找到任何答案

更新时间：太平洋标准时间09/25:02:10

使用后，我们发现多个nginx实例正在运行，如图所示：

我可以终止服务并重新启动它，但似乎通过chef或我们的cap部署在服务器上没有正确配置某些东西。如果我重新启动box，事情会如前所述正常工作，但我们也尝试终止nginx服务。我们发现这同样有效。我们的开发运营团队正在进行这方面的工作，但我们仍然对这是如何发生的或如何修复它感到困惑

更新时间：太平洋标准时间09/26:11:06

如果你愿意的话，我找到了乘客启动时的配置 在

/etc/service/

中查看，您将看到正在运行的应用程序的文件夹 在服务器上。查看您感兴趣的文件夹中的

run

文件 在中，您将看到乘客配置。这将触发一个

ruby.bin/passenger start

进程，然后触发

/tmp

nginx 应用程序重新启动时挂起的进程。我已经试着重新启动了 不同的组合，似乎有效的是杀死nginx 进程，然后运行

sudo killall ruby

以重新启动新应用程序。。。 不理想

---

因此，我们的DevOps团队为解决这个问题所做的更新围绕着乘客生成nginx的方式展开。它使用的配置是以前版本中较旧的

spawn-lv2

，对于当前版本4，我将其更改为

spawn

。这样做似乎是为了停止在

/tmp

中创建新目录，这些目录被runit脚本引用，但由于旧版本仍在运行而失败。现在看来更新是在当前的

/tmp

目录中完成的，因此进程是否仍在运行并不重要

---

此更新是对chef:default[“rackbox”][“default\u config”][“passenger\u runit”][“spawn\u method”]=“smart”

中的rackbox default属性进行的。是否可能通过.gitignore忽略了您的Gemfile？听起来bundler安装到的路径/gemset与rbenv ruby不同。您正在使用rbenv将ruby安装到/opt/ruby。我将首先确保“capistrano/bundler”将bundler安装到rbenv ruby install in/opt/ruby知道的路径。e、 g.

哪个bundle

，

哪个ruby

，或者添加rbenv知道的路径，或者以不同的方式安装bundler，这样您就可以保证rbenv知道它。@Anlek yes gem文件正确过来了。@mmay当我运行哪个ruby时我得到了“/opt/rbenv/shimmes/ruby”我得到了哪个捆绑机/opt/rbenv/shimmes/bundler，哪个捆绑机/opt/rbenv/shimmes/bundle。想法？嗯…这证实了我的直觉是错的！前几天我遇到了一个类似的问题，在我的案例中，修复路径解决了这个问题。没有使用Capistrano，所以不确定它在这里使用的是什么魔法。是否确认符号链接设置正确？它在那条路径下寻找的文件真的在那里吗？对不起，帮不上忙了！
