如何在使用dokku部署的Rails应用程序上启动Faye服务器？ [英] How to start faye server on a rails app deployed using dokku?

问题描述

我已经使用Dokku在Digitalocean上托管了Rails应用程序。我的应用程序需要通过Faye运行实时应用程序。我一直在尝试类似Dokku的Shoreman插件的方法，并将 faye：捆绑exec rackup faye.ru -s thin -E production 添加到 Procfile文件中。但是到目前为止，还没有运气，需要有关如何使我的Faye服务器为我的应用程序运行的帮助。

I've hosted my rails application on Digitalocean using Dokku. There's this need for my application to run real-time applications through Faye. I've been trying several ways like the shoreman plugin for Dokku and adding faye: bundle exec rackup faye.ru -s thin -E production to "Procfile" file. But no luck till now, need help on how I can get this Faye server running for my app.

推荐答案

可以使用Faye服务器的几个步骤（例如在端口9292上）：

You need to make several steps to have working faye server (e.g. on port 9292):

1. 您的Procfile正常


2. 在Docker上暴露端口9292。我建议安装 docker-options 插件和下一个 dokku docker-options：add timer -p 9292：9292



3. 设置您的应用程序nginx.conf。我的位置在这里：

1. Your Procfile is OK
2. Expose port 9292 on Docker. I recommend install docker-options plugin and next dokku docker-options:add timer "-p 9292:9292"

3. Setup your app nginx.conf. Mine is here:

upstream app { server 127.0.0.1:49154; }
  server {
  listen      [::]:80;
  listen      80;
  server_name app.dokku.mine;
  location    / {
    proxy_pass  http://app;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header X-Forwarded-Port $server_port;
    proxy_set_header X-Request-Start $msec;
}
  location /faye {
    proxy_redirect     off;
    proxy_set_header   Upgrade    $http_upgrade;
    proxy_set_header   Connection "upgrade";
    proxy_http_version 1.1;
    proxy_buffering    off;
    proxy_cache_bypass $http_pragma $http_authorization;
    proxy_no_cache     $http_pragma $http_authorization;
    proxy_pass http://localhost:9292;
  }
}

我建议安装 nginx-alt 插件，因为每次部署都会覆盖配置。

I suggest to install nginx-alt plugin because config is overwritten on every deploy.
