nginx 代理 apache 的问题

Question

我当前的nginx配置如下：

(当前两个)域的具体配置：

server {
    listen 443 ssl;
    server_name studiotv.service.tebusco.lan phpmyadmin.service.tebusco.lan;
    ssl_certificate /home/administrador/nginx-confs/ssl/service.tebusco.lan.crt;
    ssl_certificate_key /home/administrador/nginx-confs/ssl/service.tebusco.lan.key;
    location / {
        proxy_pass http://127.0.0.1:8180;
        proxy_set_header Host $http_host:8180;
    }
}

不匹配的 SSL 连接的默认配置：

server {
    listen 443 default ssl;
    ssl_certificate /home/administrador/nginx-confs/ssl/service.tebusco.lan.crt;
    ssl_certificate_key /home/administrador/nginx-confs/ssl/service.tebusco.lan.key;
    location / {
        return 403;
    }
}

http配置：

server {
    listen 80;
    rewrite ^ https://$host$request_uri? permanent;
}

其意图很明确：

• 将 http 流量重定向到 https。
• 将来自 phpmyadmin.service.tebusco.lan 和 studiotv.service.tebusco.lan 的每个 https:// 调用代理到 ​​apache2。这包括传递检测到的主机标头。
• 每个不匹配的 SSL 连接都必须在 nginx 中返回 403。甚至无法到达 apache2。

在 apache2 的生命周期中，我有一个默认站点和一个与 studiotv.service.tebusco.lan 匹配的非默认站点：

000-default.conf 文件（可用且已启用）：

<VirtualHost 127.0.0.1:8180>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.

    ServerName localhost
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    <Directory /var/www/html>
        Order deny,allow
        Require all granted
    </Directory>
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

studiotv.conf 文件（可用且已启用）：

<VirtualHost *:8180>
    ServerName studiotv.service.tebusco.lan
    ServerAdmin [email protected]
    DocumentRoot /var/www/studiotv

    <Directory /var/www/studiotv/>
        Options -Indexes +FollowSymLinks
        AllowOverride None
        Order deny,allow
        Allow from all
        Require all granted
    </Directory>

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    # No usamos ${APACHE_LOG_DIR} sino en su lugar /var/log/<host>
    ErrorLog /var/log/apache2/studiotv/error.log
    CustomLog /var/log/apache2/studiotv/access.log combined
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

然而，当我使用 访问浏览器时http://studiotv.service.tebusco.lan，显示的却是默认的 php 页面。

问题：我错过了什么？（apache 2.4.7，nginx 1.6.0，ubuntu server 14.04）。
