nginx 子域名的通配符 server_name 给出 index.php 404 错误

Question

我一直在使用这个 wordpress 服务器配置，它在我的本地机器上运行良好：

server {
    server_name example.example

    root /home/user/sites/example/example/html;

    index index.php index.html index.htm;

    access_log off;
    error_log /home/user/log/error.log;

    location / {
            try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
    }
}

现在我已经安装了其他 wordpress，因此我阅读了有关通配符和子域名的信息，并尝试了类似的方法：

server {
    server_name ~^(.*)\.example;

    root /home/user/sites/example/$1/html;

    index index.php index.html index.htm;

    access_log off;
    error_log /home/user/log/$1.error.log;

    location / {
            try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
    }
}

使用第一个配置，一切都运行良好，但是当我使用第二个配置时，就会出现 404 错误。

我的 error.log 文件中没有记录任何内容。

如果我尝试创建一个 index.html 并导航到该文件，一切都很好，但是当我导航到任何 php 文件时，我会出现 404 错误。

我想使用通配符配置，因为我将添加和删除站点的文件夹，并且我不想每次创建或删除文件夹时都去创建或更改 nginx 的服务器配置，但我无法使其工作。

知道我遗漏了什么吗？到处搜索，没有找到类似的东西。

以下是第二种配置的请求的 nginx 调试日志：

下面是我使用 curl -I 得到的结果：

HTTP/1.1 404 Not Found
Server: nginx/1.4.4
Date: Tue, 28 Oct 2014 21:12:21 GMT
Content-Type: text/html
Content-Length: 168
Connection: keep-alive

这是第一个配置的正常响应（没有通配符）：

已解决，感谢 Alexey Ten 的评论。我使用了命名捕获，而不是$1：

server_name ~^(?<subdomain>.*)\.example$;
root /home/user/sites/example/$subdomain/html;

下面是如何做到这一点的一个例子。

https://stackoverflow.com/questions/9578628/redirecting-a-subdomain-with-a-regular-expression-in-nginx

server {
    server_name     ~^(?<subdomain>\w+)\.domainA\.com$;

    root /home/user/sites/example/$subdomain/html;

    location / {
            rewrite ^ https://$subdomain.domainB.com$request_uri permanent;
    }
}
