ruby - 为 nginx 在 passenger 上部署了多个 Ruby on Rails 应用程序

Question

我有两个 RoR 应用程序，一个使用 ruby​​ 2.0.0 和名为 dataentry3 的 gemset(rvm 使用 2.0.0@dataentry3)，第二个应用程序使用 ruby​​ 1.9.3@v1。

我尝试通过以下方式部署这些应用:

1. rvm 使用 ruby​​-2.0.0@dataentry3
2. cd dir/app1
3. gem install passenger
4. passenger-install-nginx-module

5. 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;
       }
   }
   
   }
   

6. 一切正常 (http://my-ip)。

在这些步骤之后，我尝试在地址 http://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)

我做的步骤:

1. rvm 使用 ruby​​-1.9.3@v1
2. cd dir/app2
3. gem install passenger

4. 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) 无法运行。我收到错误:

ruby-2.0.0 和 ruby​​-1.9.3 passenger gem 之间肯定有冲突。我不明白为什么，因为新版本的 passenger 支持这个。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，但第一个不是(几乎相同的错误日志)。

Answer 1

您正在使用 rvm use...

在系统范围内设置 ruby​​ 版本

您需要在您的虚拟主机中使用 PassengerRuby 选项，检查此链接到乘客文档: http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerDefaultRuby

也可以尝试为每个应用使用单独的虚拟主机。
