Another rewrite/try files issue

Server NGINX
1

Hello,

I am having the following problem:

  • I want to have a “virtual” url e.g. “/myapp” to have a totally
    different document root e.g. “/home/stelios/myapp” (instead of the
    default ‘/var/www’)
  • locations of the type “/myapp/css/print.css” should respond with
    the specific file at the “/home/stelios/myapp” root (i.e. with
    “/home/stelios/myapp/css/print.css”
  • if the the file requested does not exist, then the “index.php”
    should be called via FastCGI with args “?u=$uri” (e.g.
    “/myapp/users/12” should be rewritten to
    “/home/stelios/myapp/index.php?u=users/12”)

I have tried the following:

location ~ /myapp/(.*) {
root /home/stelios/myapp;
try_files /$1 /$1/ /index.php?u=$1;
}

and the “default” PHP/FastCGI

location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
include fastcgi_params;
}

but it seems that it doesn’t work for the non files. In particular it
seems that after the internal redirect to index.php, the root is
overwritten and instead of calling my /home/stelios/myapp/index.php
the one at the default root ("/var/www/index.php") is beeing called.

Do you know what’s wrong? And possibl another way to achieve what I
want?

Thank you very much in advance!

P.S. I am using nginx-0.8.4 on Ubuntu

Possibly this:

location /myapp/ {
root /home/stelios;
try_files $uri @fallback;
}

and the “default” PHP/FastCGI

location @fallback {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME /home/stelios/myapp/index.php;
include fastcgi_params;
}

Thanks Brian, that almost works (although I don’t like repeating [most
of] the fastcgi config…)

But I also need to pass part of the original path as a query string. I
tried to following :

location @fallback {
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /home/stelios/myapp/index.php;
fastcgi_param QUERY_STRING u=$uri&$args;
}

which works but now for the url “…/myapp/users” the script gets a
query string like this: “u=/myapp/users” whereas I want it to be
“u=/users” (i.e. remove the “base” path). Is there any simple solution
to that? (e.g. can we pass parameters to a named location?)

Thanks!
Stelios

include fastcgi_params;
}

Thanks again!

I finally did the following which seems to work just fine:

location ~ /myapp/(.*) {
root /home/stelios/myapp;
set $args u=/$1&$args;
try_files /$1 @fallback;
}
location @fallback {
root /home/stelios/myapp;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
}

The “set $args …” directive augments the QUERY_STRING with the
original uri that is kept to the subsequent fastcgi call.

Best regards
Stelios

Oh, I see. Maybe this:

location ~ /myapp/(?.*) {
root /home/stelios;
try_files $uri /myapp/index.php?u=/$myquery;
}

location = /myapp/index.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME /home/stelios/myapp/index.php;
include fastcgi_params;
}

You can do it without any set directive. Try this.

location ~ /myapp/(?.*)$ {
root /home/stelios/myapp;
try_files /$myquery /index.php?u=/$myquery&$args;
}

location = /index.php {
root /home/stelios/myapp;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;

Remove the line below if already defined in fastcgi_params.

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

fastcgi_param SCRIPT_FILENAME /home/stelios/myapp/index.php;
fastcgi_param QUERY_STRING u=$uri;
include fastcgi_params0;
}

fastcgi_params0 is a copy of fastcgi_params without QUERY_STRING
parameter.
