Nginx 未知的“https”变量

Question

我今天早上醒来发现我一直在自学的新 Nginx 服务器不再为网站提供服务。看起来这是因为 Nginx 不再运行。但是，当我尝试启动它时，出现此错误：

Starting nginx: nginx: [emerg] unknown "https" variable
                                                           [FAILED]

现在据我所知，没有任何变化，昨天运行良好，但到目前为止我没有查到任何帮助我找到解决方案的方法。

如果我运行 service nginx restart ，我会得到以下信息：

nginx: [emerg] unknown "https" variable
nginx: configuration file /etc/nginx/nginx.conf test failed

到目前为止，我已经找到了关于此的所有内容，例如这里和其他一些地方：http : //www.howtoforge.com/forums/showthread.php? t =60733说要注释掉但是，fastcgi_params 一开始我就没有这些行。

我也试过注释掉对 https 的引用只是为了看看会发生什么，但它似乎没有任何区别。

我的 Nginx.conf 文件是：

user              nginx;
worker_processes  1;

#error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;
    autoindex off;

    map $scheme $fastcgi_https { ## Detect when HTTPS is used
        default off;
        https on;
    }

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;
    gzip_comp_level 2;
    gzip_proxied any;
    #gzip_types      text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;


    # Load config files from the /etc/nginx/conf.d directory
    # The default server is in conf.d/default.conf
    include /etc/nginx/conf.d/*.conf;

}

它目前正在运行一个测试 Magento 站点，它的 .conf 文件看起来像：

    server {
    listen 80;
    server_name freshtrifle.com;
    rewrite / $scheme://www.$host$request_uri permanent; ## Forcibly prepend a www
}

server {
    listen 80;
## SSL directives might go here
    server_name www.freshtrifle.com *.freshtrifle.com; ## Domain is here twice so server_name_in_redirect will favour the www
    root /var/www/freshtrifle.com;

    location / {
        index index.html index.php; ## Allow a static html file to be shown first
        try_files $uri $uri/ @handler; ## If missing pass the URI to Magento's front handler
        expires 30d; ## Assume all files are cachable
    }

    ## These locations would be hidden by .htaccess normally
    location ^~ /app/                { deny all; }
    location ^~ /includes/           { deny all; }
    location ^~ /lib/                { deny all; }
    location ^~ /media/downloadable/ { deny all; }
    location ^~ /pkginfo/            { deny all; }
    location ^~ /report/config.xml   { deny all; }
    location ^~ /var/                { deny all; }

    location /var/export/ { ## Allow admins only to view export folder
        auth_basic           "Restricted"; ## Message shown in login window
        auth_basic_user_file htpasswd; ## See /etc/nginx/htpassword
        autoindex            on;
    }

    location  /. { ## Disable .htaccess and other hidden files
        return 404;
    }

    location @handler { ## Magento uses a common front handler
        rewrite / /index.php;
    }

    location ~ .php/ { ## Forward paths like /js/index.php/x.js to relevant handler
        rewrite ^(.*.php)/ $1 last;
    }

    location ~ .php$ { ## Execute PHP scripts
        if (!-e $request_filename) { rewrite / /index.php last; } ## Catch 404s that try_files miss

        expires        off; ## Do not cache dynamic content
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_param  HTTPS $fastcgi_https;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param  MAGE_RUN_CODE default; ## Store code is defined in administration > Configuration > Manage Stores
        fastcgi_param  MAGE_RUN_TYPE store;
        include        fastcgi_params; ## See /etc/nginx/fastcgi_params
    }
}

我的 fastcgi_params 文件看起来像：

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

有没有人看到我遗漏的东西？我需要查看另一个文件吗？

任何建议将不胜感激，谢谢。

将此添加到 http {} 中的 Nginx 配置中。旧版 Nginx 的问题在于未定义变量。这定义了变量。

map $scheme $fastcgi_https {
    default off;
    https on;
}

没有设置 $_SERVER['HTTPS'] 不会阻止 SSL 正常工作，但会将 Magento 发送到安全页面上的无限重定向循环中。Magento 会检查当前页面是否应该是安全的，然后检查它是否真的安全。如果没有，它会重定向到安全 URL。问题是此检查检查是否存在 $_SERVER['HTTPS']。
