nginx wildcard server_name for subdomain gives index.php 404 error

Question

I've been using this server configuration for wordpress which works great on my local machine:

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;
    }
}

Now I've other wordpress installations, so I read about wildcards and subdomains and tried something like this:

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;
    }
}

With the first configuration everything works like a charm, but as soon as I use the second configuration I get 404 error.

I do not have anything logged in my error.log file.

If I try create an index.html and navigate to that file everything is fine, but when I navigate to any php file I get the 404 error.

I would like to use the wildcard configuration as I'm going to be adding and removing folders for sites and I dont want to go and create or change servers configurations for nginx everytime I create or delete a folder, but I haven't been able to make this work.

Any ideas on what I'm missing? Searched everywhere and havent found something similar.

Here is the debug log of nginx for the request with the second configuration:

And here is what I get with curl -I:

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

This is the normal response with the first configuration (without wildcards):

HTTP/1.1 200 OK
Server: nginx/1.4.4

Solved, thanks to Alexey Ten comment. I used named capture instead of $1:

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

The error is from nginx, but nothing is logged in error.log. — MauricioRobayo, Oct 28 '14 at 18:24
How are you testing this ? Post full request + response. Put debug log and post it log too for this request. — Xavier Lucas, Oct 28 '14 at 19:47
I'm testing this in firefox. Just posted the debug log as you suggested, Xavier. — MauricioRobayo, Oct 28 '14 at 21:16
It's better to use named capture, because `$1` changes every time nginx meets regexp (even `location ~ .php$`). `server_name ~^(?.*)\.example$;` — Alexey Ten, Oct 29 '14 at 11:10
Thank you very much Alexey, I used named capture as you suggested and now is working. I added your solution to the end of the post. — MauricioRobayo, Oct 29 '14 at 12:11

Here is an example how to do that.

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;
    }
}

Thank you Stony. I think the regexp you are using wont match something like `test-subdomain.example.com`. Also, I don't have the need of the rewrite rule as I'm not trying to go from domainA to domainB. Already solved using named capture as Alexey Ten said in his comment. Anyway thank you for your suggestion. – MauricioRobayo Oct 29 '14 at 12:53
This is the stackoverflow example. You can customize the regex for your needs. – René Höhle Oct 29 '14 at 12:54
