ruby - 为nginx部署在乘客上的多个Ruby on Rails应用

我有两个ror应用程序，一个是使用ruby 2.0.0和gemet dataentry3（rvm use 2.0.0@dataentry3），另一个是使用ruby 1.9.3@v1。
我试图通过以下方式部署这些应用程序：
rvm use ruby-2.0.0@dataentry3
cd dir/app1
gem install passenger
passenger-install-nginx-module
编辑nginx.conf：

http {
passenger_root /usr/local/rvm/gems/ruby-2.0.0-p195@dataentry3/gems/passenger-4.0.3;

server {
    listen       80;
    server_name  localhost;
    location / {
        passenger_ruby /usr/local/rvm/wrappers/ruby-2.0.0-p195@dataentry3/ruby;
        root /var/www/adgally/dataentry4/public;
        passenger_enabled on;
    }
}

}

一切正常（http://my-ip）。
在这些步骤之后，我尝试在addresshttp://my-ip/v1上部署第二个应用程序（新的phusion passenger允许运行多个ruby版本，see here）
我所做的步骤：
rvm use ruby-1.9.3@v1
cd dir/app2
gem install passenger
编辑nginx.conf：

http {
passenger_root /usr/local/rvm/gems/ruby-2.0.0-p195@dataentry3/gems/passenger-4.0.3;

server {
    listen       80;
    server_name  localhost;
    location / {
        passenger_ruby /usr/local/rvm/wrappers/ruby-2.0.0-p195@dataentry3/ruby;
        root /var/www/adgally/dataentry4/public;
        passenger_enabled on;
    }
location /v1 {
     passenger_ruby /usr/local/rvm/wrappers/ruby-1.9.3-p429@v1/ruby;
     root /var/www/adgally/v1/public;
     passenger_enabled on;
}
}

}

在此之后，第二个应用程序（http://my-ip/v1）无法工作。我有个错误：

ruby-2.0.0和ruby-1.9.3乘客宝石之间一定有冲突。我不明白为什么，因为新版《乘客》支持这一点。将passenger_root指令更改为/usr/local/rvm/gems/ruby-1.9.3-p429@v1/gems/passenger-4.0.3后，第二个应用程序开始工作，但第一个应用程序不工作（几乎相同的错误日志）。

最佳答案

您使用rvm use...在系统范围内设置ruby版本
您需要在虚拟主机中使用passengerruby选项，请选中指向乘客文档的此链接：
http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerDefaultRuby
同时尝试为每个应用使用单独的虚拟主机。
