ruby-on-rails - 尝试使用 nginx 和 unicorn 将 Rails 应用程序配置为 SSL 时出现太多重定向错误

Question

我正在尝试使用 Nginx 和 Unicorn 配置带有 SSL 的 Rails 应用程序。 我正在尝试在本地进行设置。为此，我首先使用 OpenSSL 为 Nginx 创建了一个自签名证书。我关注了document用于创建自签名证书。之后，我在 http block 中如下配置了我的 nginx.conf:

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;
        }
    }
}

我尝试在本地进行设置，并在本地启动了 Unicorn。我将 127.0.0.1 映射到 /etc/hosts 中的 dev.myapp.com。但是在启动服务器后，当我尝试 ping 应用程序时，它在 Chrome 中给出了以下错误:

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

在 Firefox 中出现以下错误:

The page isn't redirecting properly

nginix.access.log 显示以下结果:

谁能帮我找到解决方案？

Answer 1

您缺少标题:

proxy_set_header X-Forwarded-Proto https;

让我引用一个综合post这很好地解释了 Rails 如何处理 Nginx 上的 HTTPS:

force_ssl relies on the HTTP_X_FORWARDED_PROTO HTTP header to determine whether or not the request was an HTTPS request. If this setting isn't set to https then you will end up with an infinite redirect loop as force_ssl will always think the forwarded request isn't HTTPS.
