Apache 上的 Nginx 给出 502 Bad Gateway

我正在尝试通过 Apache 运行 Nginx。

我的配置是，我将 Apache 设置为监听端口8080而不是80。

然后我设置 Nginx 通过端口将所有请求代理到同一个域8080：

upstream app {
    server example.com:8080;
}

server {
    listen 80;
    server_name example.com;

    ssl_protocols TLSv1.2;

    charset utf-8;

    index index.html index.htm index.php;

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/example.com-error.log error;

    location / {
        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_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass https://app/;
        proxy_redirect off;

        # Handle Web Socket connections
        proxy_http_version 1.0;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

然后我设置了 Apache 配置，它似乎工作正常，因为我可以访问我的网站http://example.com:8080没有什么问题。

<VirtualHost *>
    DocumentRoot "/home/forge/example.com"
    ServerName example.com
    ServerAlias www.example.com
    CustomLog /var/log/httpd/example_com_access.log common
    ErrorLog /var/log/httpd/example_com_error.log

        <Directory /home/forge/example.com/>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

</VirtualHost>

但当尝试去http://example.com/我明白了502 Bad Gateway - nginx/1.8.0。

任何想法如何解决这一问题？

我需要这个的原因是我有一个 Web 服务器，其中有很多使用 Nginx 的网站，但我需要其中一些（仅其中一些）网站运行 Apache 规则而不是 Nginx 规则。

我正在运行 Ubuntu 14.04。
