ruby-on-rails - 使用子域在单个 Nginx 上运行多个 Rails 应用程序

Question

我正在尝试弄清楚如何让第二个 Rails 应用程序在我的服务器上的子域下运行。这是我的设置:

(App1) Primary Rails 应用程序 -> http://humani.se

(App2) 辅助 Rails 应用程序 -> http://supportme.humani.se

域名是通过GoDaddy购买的，目前我的子域名指向http://humani.se:3000 (通过 GoDaddy 面板)，您只需访问该 URL 即可看到它的效果。我知道，我知道——App1 在生产环境中运行，而 App2 在开发环境中运行，这不是好的做法。我只是想看看我是否能让它工作。

Nginx session :

# Primary Application Server
upstream humanise {
  # for UNIX domain socket setups:
  server unix:/home/jeff/srv/humani.se/tmp/sockets/unicorn.sock fail_timeout=0;
  # server localhost:8080;
}

server {
  server_name humani.se www.humani.se;

  # path for static files
  root /home/jeff/srv/humani.se/public;

  try_files $uri/index.html $uri.html $uri @humanise;

  location @humanise {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    # proxy_pass http://unix:/home/jeff/srv/humani.se/tmp/sockets/unicorn.sock;
    proxy_pass http://humanise;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

# Secondary Application Server
upstream supportme {
  server localhost:3000;
}

server {
  server_name supportme.humani.se;

  try_files $uri/index.html $uri @supportme;

  location @supportme {
    proxy_pass http://supportme;
    proxy_set_header Host $host;
    proxy_buffering off;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

看起来很有效，对吧？没有!因此，除了 Rails 方面，所有路线似乎都有效。如果您尝试登录(使用任何/没有凭据)，您也会看到错误。基本上，URL 助手不在 Controller 端工作。 View 中的那些( anchor 超链接)工作得很好。来自服务器日志:

您可以清楚地看到它正在重定向到正确的 URL，但随后得到的是/.humani.se/。某个地方的人必须知道这件事!

感谢任何帮助!

首先不要让g​​odaddy指向端口，humani.se和supportme.humani.se都指向同一个IP，让nginx重定向每个到正确的应用程序，就像你可以在端口 3000 上运行 app1 和在端口 3001 上运行 app2 然后在 nginx 上做一个简单的代理

server {
  server_name humani.se;
  location / {
    proxy_pass http://localhost:3000;
  }
}
server {
  server_name support.humani.se;
  location / {
    proxy_pass http://localhost:3001;
  }
}

这应该可以解决问题，告诉我你得到了什么。
