I am trying to setup my development nginx/PHP server with a basic master/catch-all vhost config so that I can created unlimited ___.framework.loc domains as needed.

server {
        listen 80;
        index index.html index.htm index.php;

        # Test 1
        server_name ~^(.+)\.frameworks\.loc$;
        set $file_path $1;
        root    /var/www/frameworks/$file_path/public;

        include /etc/nginx/php.conf;
}

However, nginx responds with a 404 error for this setup. I know nginx and PHP are working and have permission because the localhost config I'm using works fine.

server {
        listen 80 default;
        server_name localhost;
        root /var/www/localhost;
        index index.html index.htm index.php;

        include /etc/nginx/php.conf;
}

What should I be checking to find the problem? Here is a copy of that php.conf they are both loading.

location / {
        try_files $uri $uri/ /index.php$is_args$args;
}

location ~ \.php$ {

        try_files $uri =404;

        include fastcgi_params;
        fastcgi_index index.php;

        # Keep these parameters for compatibility with old PHP scripts using them.
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        # Some default config
        fastcgi_connect_timeout        20;
        fastcgi_send_timeout          180;
        fastcgi_read_timeout          180;
        fastcgi_buffer_size          128k;
        fastcgi_buffers            4 256k;
        fastcgi_busy_buffers_size    256k;
        fastcgi_temp_file_write_size 256k;
        fastcgi_intercept_errors    on;
        fastcgi_ignore_client_abort off;
        fastcgi_pass 127.0.0.1:9000;

}
