为Phusion乘客应用程序设置环境变量

问题描述

我已经设置了乘客在开发（Mac OS X），它的工作是完美的。唯一的问题是后来出现：现在我有一个自定义的 GEM_HOME 路径和ImageMagick二进制文件安装在/ usr / local 。我可以将它们放在获取源代码的shell rc文件中，并解决了从控制台产生的进程的环境变量;但乘客呢？相同的应用程序在运行时无法找到我的宝石。

解决方案

我知道两个解决方案。第一个（记录在案的）基本上与manveru的 - 直接在您的代码中设置ENV变量。

第二个是在Passenger使用的Ruby解释器周围创建一个包装，并记录了（寻找passenger_with_ruby）。要点是您创建（并将您的Apache配置中的PassengerRuby指向）/ usr / bin / ruby​​_with_env，一个可执行文件，包括：

 ＃/ bin / bash 
 export ENV_VAR = value 
 / usr / bin / ruby​​ $ * 
  

两个工作;我想，前一种方法是一点点黑客。

I've set up Passenger in development (Mac OS X) and it works flawlessly. The only problem came later: now I have a custom GEM_HOME path and ImageMagick binaries installed in "/usr/local". I can put them in one of the shell rc files that get sourced and this solves the environment variables for processes spawned from the console; but what about Passenger? The same application cannot find my gems when run this way.

解决方案

I know of two solutions. The first (documented here) is essentially the same as manveru's—set the ENV variable directly in your code.

The second is to create a wrapper around the Ruby interpreter that Passenger uses, and is documented here (look for passenger_with_ruby). The gist is that you create (and point PassengerRuby in your Apache config to) /usr/bin/ruby_with_env, an executable file consisting of:

#!/bin/bash
export ENV_VAR=value
/usr/bin/ruby $*

Both work; the former approach is a little less hackish, I think.
