嘗試使用nginx和unicorn將rails應用程序配置為SSL時，重定向錯誤太多

Question

我正在嘗試使用Nginx和Unicorn配置帶有SSL的Rails應用程序。 我想在本地設置它。 為此，我首先使用OpenSSL為Nginx創建了一個自簽名證書。 我按照文檔創建了自簽名證書。 之后我在http塊中配置了我的nginx.conf ，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;
        }
    }
}

我嘗試在本地設置它，並在本地啟動Unicorn。 我將127.0.0.1映射到/etc/hosts dev.myapp.com 。 但是在啟動服務器之后，當我嘗試ping應用程序時，它在Chrome中給出了以下錯誤：

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

和Firefox中的以下錯誤：

The page isn't redirecting properly

nginix.access.log顯示以下結果：

任何人都可以幫我找到解決方案嗎？

Answer 1

你錯過了一個標題：

proxy_set_header X-Forwarded-Proto https;

讓我引用一篇全面的文章 ，很好地解釋了Rails如何在Nginx上處理H​​TTPS：

force_ssl依賴於HTTP_X_FORWARDED_PROTO HTTP標頭來確定請求是否是HTTPS請求。 如果此設置未設置為https那么您將最終獲得無限重定向循環，因為force_ssl始終認為轉發的請求不是HTTPS。

復制評論中的答案，以便從“未答復”過濾器中刪除此問題：

嘗試將'重寫^ /（。*）http：// ...'更改為'重寫^ /（。*）https：// ...'並從第二個服務器塊中刪除listen 80
