Unicorn/nginx/rails4 通过 mina 部署 - 504 网关超时和独角兽日志中的错误

【问题标题】：Unicorn/nginx /rails4 deployed via mina - 504 gateway timeout and errors in unicorn logUnicorn/nginx/rails4 通过 mina 部署 - 504 网关超时和独角兽日志中的错误
【发布时间】：2016-05-08 05:17:03
【问题描述】：

编辑.... 我试过用 Cap 和 puma 设置整个事情，而 puma 给了我和独角兽一样的错误。好像和active_suppport有关。。。。

任何帮助...

彪马错误日志：

我无法让我的生产系统运行。我遵循了优秀的指南：https://www.ralfebert.de/tutorials/rails-deployment/ 让整个事情运行起来。我从一个简单的演示应用程序开始并运行它。之后，我对我的应用程序做了同样的事情。我已经运行了整个部署，我可以启动 unicorn 和 nginx 而不会摔倒……但没有雪茄……我从 nginx 收到 504 Gateway Time-out 和 nginx 日志中的大量错误。似乎 rails 根本没有抱怨……因为它并没有真正运行。

我可以在我的开发机器上运行相同的应用程序 - 所以它不应该是我的代码。我怀疑这可能是宝石的一些依赖性问题 - 独角兽日志中的最后一条信息是“刷新宝石列表”，然后才抛出

这里有一些日志和设置：

Nginx 日志：

独角兽设置：

app_path = File.expand_path(File.join(File.dirname(__FILE__), '../../'))
#app_path = '/home/pi/rails/demo/releases/4'

listen '127.0.0.1:4000'

stderr_path File.join(app_path, 'current/log/unicorn.log')

nginx 设置：

upstream phototank {
    server unix:/home/pi/rails/phototank/shared/unicorn.sock fail_timeout=0;
}

server {
    listen 80;
    server_name 192.168.2.103;

    index index.htm index.html;

    location / {

    }

    location @app {

        proxy_set_header Host $http_host;
        proxy_redirect off;

    server_name 192.168.2.103;
    return 301 http://192.168.2.103$request_uri;

【问题讨论】：

  • 您有两个具有相同listen 和server_name 的服务器块。那是行不通的。
  • 我修复了它并删除了一些警告，但没有解决问题... :-(

标签： ruby-on-rails nginx unicorn mina


【解决方案1】：

虽然我还没有找到答案，但我会结束这个问题......我发现这就是问题所在：

Unable to load application: LoadError: No such file to load -- Find

我有一个控制器：

require 'Find'

class CatalogsController < ApplicationController
...

当我删除“需要查找”时，一切正常。我给我留下了一个关于如何在控制器中要求模块（查找）的新问题？？？
