Try_files acting weird, maybe affected by IF?

Server NGINX
1

Hi,
I’ve been trying to force nginx to dynamically handle hosts. This is my
configuration file

    server {
            listen          127.0.0.1:80;
            server_name

~^(:?(?.+).)?(?[^.]+.[^.]+)$;
index index.php index.html;

            location / {
                    set             $try_dir $domain;
                    if (-d /var/www/hosts/$second.$domain) {
                            set     $try_dir $second.$domain;
                    }

                    root            /var/www/hosts/$try_dir;
                    try_files       $uri $uri/ /index.php;
            }

            # pass the PHP scripts to FastCGI server listening on

127.0.0.1:9000
location ~ .php$ {
set $try_dir $domain;
if (-d /var/www/hosts/$second.$domain) {
set $try_dir $second.$domain;
}

                    root            /var/www/hosts/$try_dir;
                    include         fastcgi_params;
                    fastcgi_param   SERVER_NAME     $try_dir;
                    fastcgi_pass    127.0.0.1:9000;
                    fastcgi_index   index.php;

                    fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
                    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;

                    try_files $uri =404;
            }
    }

It receives request, checks if exists corresponding subdirectory, if
not, passes to “main” directory.
I know I shouldn’t be using the IF statement, but I’ve tried many, but
havent figured this out without the if.

So let’s have a request

    $ curl http://hosiplan.l/rewrite

The directory /var/www/hosts/hosiplan.l exists, there is index.php file
and no “rewrite” file. This should be handled by the index.php

    ...
    [debug]: *1 using configuration "/"
    ...
    [debug]: *1 http script file op 0000000000000002

“/var/www/hosts/.hosiplan.l”
[debug]: *1 http script file op false
[debug]: *1 http script if
[debug]: *1 http script if: false
…
[debug]: *1 try files phase: 11
…
[debug]: *1 try to use file: “/rewrite”
“/var/www/hosts/hohosiplan.l/rewrite”
…
[debug]: *1 try to use dir: “/rewrite”
“/var/www/hosts/hohosiplan.l/rewrite”
…
[debug]: *1 try to use file: “/index.php”
“/var/www/hosts/hohosiplan.l/index.php”
[debug]: *1 internal redirect: “/index.php?”
…

This works like a charm. Pure perfection. But when I use a subdomain

    $ curl http://blaphp.hosiplan.l/rewrite

The directory /var/www/hosts/blaphp.hosiplan.l exists, there is
index.php file and no “rewrite” file. This should be handled by the
index.php

    ...
    [debug]: *3 using configuration "/"
    ...
    [debug]: *3 http script file op 0000000000000002

“/var/www/hosts/blaphp.hosiplan.l”
[debug]: *3 http script if
…
[debug]: *3 try files phase: 11
…
[debug]: *3 http filename:
“/var/www/hosts/blaphp.hosiplan.l/rewrite”
2012/06/16 17:05:45 [error] 2604#0: *3 open()
“/var/www/hosts/blaphp.hosiplan.l/rewrite” failed (2: No such file or
directory), client: 127.0.0.1, server:
~^(:?(?.+).)?(?[^.]+.[^.]+)$, request: “GET /rewrite
HTTP/1.1”, host: “blaphp.hosiplan.l”

And that’s where I’m stuck. Any kind of input would be really
appreciated.

In the second case the “if (-d …)” is matched, and you are
hitting “try_files won’t work due to if” example from here:

Trivial solution in this case is to move your ifs to server
level.
