使用Nfex的子目录上的Wordpress使用没有输入文件的代理传递错误

希望你能提供帮助,但我在尝试访问博客的管理部分时收到以下错误.

没有指定输入文件.

实际的博客工作正常但不是登录/管理区域.

根据标题,博客在单独的服务器上是主域,并使用代理传递将请求转发给它.

upstream blog {
    server 111.111.111.111:443 weight=2 max_fails=3 fail_timeout=60s;
}

server{
  ...
  location /blog {
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        proxy_pass https://blog;
    }
}

我在博客服务器上的nginx设置如下.

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name www.domain.com;
    root /home/www.domain.com/public;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /blog/index.php?$query_string;
    }

    error_log  /var/log/nginx/www.domain.com-error.log error;

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php5.6-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }

}

如果它有帮助,这里是fastcgi_params.

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_FILENAME     $request_filename;
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;
fastcgi_param   HTTPS           $https if_not_empty;
fastcgi_param   REDIRECT_STATUS     200;
fastcgi_param   HTTP_PROXY  "";

我明白我相信PHP无法找到index.php文件？

希望有人可以帮忙..
