Nginx 默认：为什么位置/不转发到反向代理？

Question

我希望 NGINX 将任何对域名http://home.com 的请求转发到proxy_pass http://localhost:8866;。我在ownCloud的文档根目录所在的NGINX配置文件中设置了一个根root /home/owncloud;。这应该指向http://home.com/owncloud 在http://localhost:8866 下我有一个运行托管Wordpress 的Docker 容器。但是，当我尝试访问 http://home.com 时，NGINX 总是将反向代理指向服务器的实际文档根目录 (root /home/owncloud)

感谢您对此的意见 - 我已经浏览了很多文档，但目前我自己无法找到解决方案。谢谢！

这是我的 NGINX 配置文件：

  server unix:/var/run/php5-fpm.sock;
  }

  listen 80;

  index index.html index.htm index.php;

  return 301 https://$server_name$request_uri;
  }

        ssl on;
        listen 443 ssl;

如果您需要在本地主机上将所有请求转发到另一个端口，您只需要这个：

location / {
    proxy_set_header        Host $host;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        X-Forwarded-Proto $scheme;
    proxy_pass              http://localhost:8866$request_uri;
    proxy_read_timeout  90;
}

注意，斜线/ 前没有“=”等号。 location / {} 表示“/ 的完全匹配”。 在您的代码中，没有真正尝试将 all 请求转发到 localhost。仅转发对索引页面（文档根，即“/”）的请求。

如果您将 所有 请求传递给 localhost:8866 的进程，则甚至不会测试任何其他 location 部分，因此一旦您确保您的 proxy_pass 有效，您可以删除他们。
