使用nginx和unicorn将rails应用程序配置为SSL时，重定向错误太多。

Question

我正在尝试使用SSL配置Rails应用程序，使用Nginx和Unicorn。我正试图在当地设置它。为此，我首先使用OpenSSL为Nginx创建了一个自签名证书。我按照文档创建了自签名证书。之后，我在nginx.conf块中配置了http，如下所示：

upstream unicorn_myapp {
    # This is the socket we configured in unicorn.rb
    server unix:root_path/tmp/sockets/unicorn.sock fail_timeout=0;
}

server {
    listen 80;
    server_name dev.myapp.com;
    rewrite ^/(.*) http://dev.myapp.com/$1 permanent;
}

server {
    listen                80;
    listen                443 ssl;
    server_name           dev.myapp.com;
    ssl                   on;
    ssl_certificate       /etc/nginx/ssl/server.pem;
    ssl_certificate_key   /etc/nginx/ssl/server.key;
    ssl_protocols         SSLv3 TLSv1;
    ssl_ciphers           ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP;
    ssl_session_cache     shared:SSL:10m;

    root root_path/public;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://unicorn_myapp;
            break;
        }
    }
}

我试着在本地设置它，然后在本地启动Unicorn。我将127.0.0.1映射到dev.myapp.com in /etc/hosts。但是在启动服务器后，当我试图点击这个应用程序时，它在Chrome中出现了以下错误：

This webpage has a redirect loop
Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.

以及Firefox中的以下错误：

The page isn't redirecting properly

nginix.access.log显示了以下结果：

有谁能帮我找到解决办法吗？

Answer 1

您缺少了一个标题：

proxy_set_header X-Forwarded-Proto https;

让我引用一个全面的帖子，很好地解释Rails如何在Nginx上处理HTTPS：

force_ssl依赖于header来确定请求是否是HTTPS请求。如果没有将此设置设置为https，则最终会有一个无限重定向循环，因为force_ssl总是认为转发的请求不是HTTPS。

Answer 2

从注释中复制答案，以便从“未回答”筛选器中删除此问题：

尝试将“rewrite ^/(.*) http://...”更改为“rewrite ^/(.*) https://...”，并从第二个服务器块中删除侦听80。
