Quick question about try_files

Server NGINX
1

Hello, all.

nginx version: nginx/0.7.67

This works great to look first in fast local storage, and then fall back
to
slower storage for older archives:

location ^~ /providers/ {
  error_page 404 = @archives;
  log_not_found off;
}
location @archives {
  rewrite "/providers/(.*)" /archives/providers/$1 last;
}

I thought I could tidy this up by doing the following, but it doesn’t
work:

location ^~ /providers/ {
  try_files $uri /archives$uri @mongrel_app;
}

Anyone see why? Thanks in advance.

This rewrites to /archives/… and searches for location again.
Request will be handled elsewhere, and it’s not known how it will
be handled from the config snippet provided.

This should work as long as root for archives matches one for
providers. But won’t work as long as you have something like

location ^~ /archives/ {
    root /path/to/another/storage;
}

in your config.

Maxim,

Thanks for your quick reply!

I should have included that in both cases, the default handler is this:

location / {
  try_files $uri $uri/index.html @mongrel_app;
}

And, there is no /archives/ handler. So, here are the snippets that I
think
are relevant. Working:

location ^~ /providers/ {
  error_page 404 = @archives;
  log_not_found off;
}
location @archives {
  rewrite "/providers/(.*)" /archives/providers/$1 last;
}
location / {
  try_files $uri $uri/index.html @mongrel_app;
}

Not working:

location ^~ /providers/ {
  try_files $uri /archives$uri @mongrel_app;
}
location / {
  try_files $uri $uri/index.html @mongrel_app;
}

Also, I should mention that it in the not-working case, the behavior is
that
it will correctly find the file in /providers/… but if the file is
moved
to /archives/providers/…, it will no longer find it.

I’ve put all the location directives here: http://pastie.org/1438414

Thanks, again,

Maxim,

Again, thanks for your help. I created the debug log and found a
permissions
problem.

I had dismissed permissions as a possible reason for the behavior,
because
it was working fine with the one configuration (I promise!). But,
whatever.
A couple of permissions changes and voila! Everything works as expected.

I sincerely appreciate your help.

This should work (and works here without problems, just tested in
both 0.9.3 and 0.7.67). Note though that the second form (with
try_files) won’t work with directories.

Could you please provide debug log for working and non-working
cases? See Debugging | NGINX for basic
instructions.
