Try_files for alias

Server NGINX
1

How do I make this work?

location ~ /~someapp(.*)$ { alias /home/someapp/root$1; try_files $uri
/~someapp/err404.htm; }

The try_files never catch the $uri (nor $1) and returns 500 (redirection
cycle)

Am I ‘forced’ to use error_page in this case?

This works:

location ~ /~someapp(.*)$ { alias /home/someapp/root$1; error_page 404
/~someapp/err404.htm; }

and without regex the error_page and try_files seem to be completely
ignored:
neither
location /~someapp/ { alias /home/someapp/root/; error_page 404
/~someapp/err404.htm; }
nor
location /~someapp/ { alias /home/someapp/root/; try_files $uri
/~someapp/err404.htm; }
works.

I also find using this works

location ~ /~someapp(.*)$ {
root /home/someapp/root/;
try_files $1 /~someapp/err404.htm;
}

so, alias and try_files just doesn’t work together?

If request is “/~someapp/one”, then this location

location /~someapp/ {
    alias     /home/someapp/root/;
    try_files $uri   /~someapp/err404.htm;
}

will test /home/someapp/root/one existence.

As to

location ~ /~someapp(.*)$ {
    alias /home/someapp/root$1;
    try_files $uri /~someapp/err404.htm;
}

this “alias” with captures is special case.
A “root” is always just prefix to URI and “try_files” tests “root$uri”.
An “alias” without captures replaces location part in URI with
the “alias” value, and “try_files” tests “alias/modified_uri”
An “alias” with captures replaces a whole URI with the “alias” value,
and “try_files” tests “alias/$uri”, and $uri is surpplus here.
You need just to pass empty value to “try_files”:

location ~ /~someapp(.*)$ {
    alias /home/someapp/root$1;
    try_files ""  /~someapp/err404.htm;
}

Thanks for the explanation (and it works). It’d be nice to have this
kind of information available in documentation somewhere :slight_smile:

Or maybe I (or someone else) can update the wiki… (the alias part is
outdated)

I just noticed it doesn’t work properly (bug?)
location ~ ^/~([^/]+)(..php)$ {
alias /home/$1/public_html$2;
try_files “” @404;
include php_params;
}
location ~ ^/~([^/]+)(.)$ {
alias /home/$1/public_html$2;
try_files “” @404;
}

php_params:
fastcgi_pass 127.0.0.1:8000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;

from phpinfo():

_SERVER[“SCRIPT_NAME”] ^/~([^/]+)(..php)$
_SERVER[“REQUEST_URI”] /~edho/
_SERVER[“DOCUMENT_URI”] ^/~([^/]+)(..php)$

…still in regex form?

as for static file, it always returned with mime type of
application/octet-stream ( http://pastebin.com/m7d2c8f6e )

Tip: I had overcame alias+try_files problem by using symlinks insted of
aliases.
