AWS EC2、Nginx SSL 问题

Question

我在 AWS EC2 实例上运行 Rails 应用程序，Nginx 1.4.6 充当反向代理并提供 SSL 证书。

我很确定我的问题出在我的 Nginx 配置上。这里是：

upstream puma {
  server unix:///home/deploy/apps/appname/shared/tmp/sockets/appname-puma.sock;
}

server {
  listen 443;

  ssl on;
  ssl_certificate /etc/nginx/ssl/appname.chained.crt;
  ssl_certificate_key /etc/nginx/ssl/appname.key;

  root /home/deploy/apps/appname/current/public;
  access_log /home/deploy/apps/appname/current/log/nginx.access.log;
  error_log /home/deploy/apps/appname/current/log/nginx.error.log info;

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

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

server {
  listen 80;
  return 301 https://$host$request_uri;
}

当我尝试运行时curl -v https://appname.co.uk，curl 返回：

* Rebuilt URL to: https://appname.co.uk/
*   Trying 52.27.236.227...
* found 187 certificates in /etc/ssl/certs/ca-certificates.crt

< HTTP/1.1 301 Moved Permanently
< Server: nginx/1.4.6 (Ubuntu)
< Date: Sat, 26 Dec 2015 15:51:14 GMT
< Content-Type: text/html
< Transfer-Encoding: chunked
< Connection: keep-alive
< 

这应该显示我的 rails 应用程序的主页。这* ALPN, server did not agree to a protocol条线重要吗？为什么 Nginx 返回 301 Moved Permanently？

非常感谢，如果有更多信息有用，请告诉我。

您的 nginx 配置在端口 443 上没有显示任何重定向，并且您声称在 nginx 前面没有负载均衡器，因此重定向可能来自的唯一其他地方是...您的应用程序。

我看到您正在 https 上运行该应用程序，但您还没有告诉 Rails 这件事。特别是，您的 nginx 配置丢失：

        proxy_set_header X-Forwarded-Proto $scheme;

我怀疑您的应用程序知道其自己的预期 URL 并尝试重定向到它，因为它认为传入的 URL 不规范。

添加此内容并查看重定向是否停止。
