利用乘客同时运行的Rails 3.0和Rails 3.1的应用程序（使用不同的RVM gemsets） [英] Using passenger to run both Rails 3.0 and Rails 3.1 app (using different rvm gemsets)

问题描述

我只是跟着这些路线安装新RVM宝石和安装导轨-3.1.0 .RC2我的本地机器上。起初我得到一个错误乘客称耙0.9.2宝石无法加载，但我发现这提醒我跑$客车安装-Apache2的模块。安装它精细促使我下面添加到我的Apache的配置文件（/etc/apache2/httpd.conf）：

I just followed these directions for installing a new rvm gemset and installing rails-3.1.0.rc2 on my local machine. At first I was getting a Passenger error saying the rake-0.9.2 gem could not be loaded, but I found this reminding me to run "$ passenger-install-apache2-module". It installed fine prompted me to add the following to my Apache config file (/etc/apache2/httpd.conf):

LoadModule passenger_module /Users/robs/.rvm/gems/ruby-1.9.2-p180@rails-3.1/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
PassengerRoot /Users/robs/.rvm/gems/ruby-1.9.2-p180@rails-3.1/gems/passenger-3.0.7
PassengerRuby /Users/robs/.rvm/wrappers/ruby-1.9.2-p180@rails-3.1/ruby

不过，目前已经有三条线有从不同的宝石：

However, there are already three lines there from a different gemset:

LoadModule passenger_module /Users/robs/.rvm/gems/ruby-1.9.2-p180@rails-3.0/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
PassengerRoot /Users/robs/.rvm/gems/ruby-1.9.2-p180@rails-3.0/gems/passenger-3.0.7
PassengerRuby /Users/robs/.rvm/wrappers/ruby-1.9.2-p180@rails-3.0/ruby

如果我离开这两个套系有注释掉（中@轨-3.1宝石的是最后一个），并重新启动Apache，我的Rails应用程序3.0将不会启动。我发现自己不得不注释掉轨3.1宝石线，重新启动Apache，然后运行$ RVM使用ruby-1.9.2-p180@rails.3.0。如果我想运行Rails的3.1应用程序，我需要做的是相反的。

If I leave both sets of lines there uncommented (the @rails-3.1 gemset's is last), and restart Apache, my Rails 3.0 app won't start. I find myself having to comment out the rails 3.1 gemset lines, restart Apache, and then run "$ rvm use ruby-1.9.2-p180@rails.3.0". If I want to run the Rails 3.1 app, I have to do the opposite.

有没有办法同时拥有能够在同一时间没有这些额外的步骤来运行？

Is there a way to have both be able to run at the same time without these extra steps?

我用它作为一个例子来建立自己的开发环境，nginx的。

I used it as an example to setup my own development environment with nginx.
