对于 ruby​​ 1.8.7，Passenger + RVM 返回 502（passenger_root 位于 ruby​​ 1.9.3）

我正在使用 Passenger + RVM + Nginx，为 Ruby 1.9.3 配置的 Rails 应用程序运行良好，但为 1.8.7 配置的 Rails 应用程序总是返回 502 错误。有人能发现问题吗？

我的配置如下：

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    passenger_root /usr/local/rvm/gems/ruby-1.9.3-p448@mygems/gems/passenger-4.0
    passenger_log_level 2;
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/conf/sites-enabled/*;

    # from sites-enabled/qa.pinneyinsurance.com
    server {
        listen       80;
        server_name  qa.pinneyinsurance.com;
        index  index.html index.htm;
        root   /var/www/pinneyinsurance.com/current/public;
        passenger_enabled on;
        passenger_ruby /usr/local/rvm/wrappers/ruby-1.8.7-p374@mygems/ruby;
    }
}

我的 nginx 错误日志输出以下内容：

答案1

操作系统 Debian 3.2？你确定吗？实际是 7。

502/Bad Gateway 通常意味着您的后端/上游已关闭。

你能通过 1.8.7 和 webrick 启动你的 rails 应用程序吗？我会从这一点开始调查。如果这有效

我不太了解 rails + airline + nginx-integration，但我看到 http{} (passenger-root) 和 server {} airline_ruby 中使用了 2 个不同的 rvm-path。也许这是一个问题？

顺便问一下：为什么不获得付费支持？
