Another auth/location question - probably very simple to fix :)

Server NGINX
1

prompts but only on the exact /wordpress/admin match:

location /wordpress/admin {
auth_basic “wordpress”;
auth_basic_user_file /home/foo/web/foo.com/.htpasswd
location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
fastcgi_index index.php;
}
}

doesn’t prompt at all:

location ~ /wordpress/admin(.+) {
auth_basic “wordpress”;
auth_basic_user_file /home/foo/web/foo.com/.htpasswd
location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
fastcgi_index index.php;
}
}

am i missing something? i thought i had it fully secured. not sure if
behavior changed from 0.7.4 or so to 0.7.10

i want everything under /wordpress/admin/ to require basic auth. i
could have sworn this worked properly before, but now the first one
prompts only for the / index, if i enter in a direct URL i get no
prompt (like /wordpress/admin/post-new.php)

thanks…

But the better way is disable regex searches:

  • location /wordpress/admin {
  • location ^~ /wordpress/admin {

Do you have something like “location ~ .php$” before
“location ~ /wordpress/admin(.+)” ?
If so, the former matchs “/wordpress/admin/post-new.php”.

that breaks the php parsing inside of wp-admin… i need PHP to still
parse inside of the protected directory, i have this inside of that
block:

location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
fastcgi_index index.php;
}

yes i do, here’s the entire config:

server {
listen 80;
server_name foo.com;
index index.php index.html;
root /home/mike/web/foo.com/;
location /wordpress/admin {
auth_basic “wordpress”;
auth_basic_user_file /home/mike/web/foo.com/.htpasswd;
location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
fastcgi_index index.php;
}
}
location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
fastcgi_index index.php;
}
if (!-e $request_filename) {
rewrite ^(.+)$ /wordpress/index.php?q=$1 last;
}
}

sorry i -did- have it before the location block, i also tried it
after. both work the same

“^~” does not disable regex for inclusive location.
It disables regex locations of the the same level only.

Apply the attached patch that allows POST for non-existent static files
and try the following configuration:

server {
    listen 80;
    server_name foo.com;
    index index.php index.html;
    root /home/mike/web/foo.com/;

    error_page 404 = /wordpress/index.php?q=$request_uri;

    location / {
    }

    location ^~ /wordpress/admin {

        auth stuff

        location ~ \.php$ {
             fastcgi_pass 127.0.0.1:11000;
             # fastcgi_index is not needed here
        }
    }

    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:11000;
        # fastcgi_index is not needed here
        }

okay, so how would you write out that server block so that php works
in both normal and in admin, and admin is behind basic auth?

What patch do you mean ?

(BTW, it works right now even without the patch but probably not for

GET worked long ago. The patch for POST only.

Okay, I applied two patches and that same config that was working in
0.7.8 and wordpress admin is back to not parsing PHP…

Perhaps you used the wrong -p or --strip option?

Ideally all three of these patches to work in 0.7.10:

  1. 'Re: error_page and log_not_found in nginx 0.7.8' - MARC -
  2. 'Re: Directory permissions behavior changed?' - MARC - applies
  3. and the static post patch you just supplied - it applies with fuzz

You may set it on, it can be turned on/off on http/server/location
levels.
I usually set it off for mirror-on-demand locations:

    location /dir/ {
        open_file_cache_errors  off;
        error_page  404 = @fetch;
    }

    location @fetch {
        proxy_store  on;
        ...
    }

okay, now i haven’t changed my config, but i am getting prompted to
download/PHP is not parsing for both 0.7.8 and 0.7.10!

so now my PHP is not being parsed inside of the admin location block
at all… and i’m using my original 0.7.8 with the two patches i
already had on it. i don’t know how this has happened now.

and i want to ask a clarification: will maxim’s patch be adopted
as-is, and if people don’t like that behavior they have the option to
set the open_file_cache_errors option? i am trying to figure out if it
will behave how i want by default, or if i am the one that needs to
make a config change :slight_smile:

okay. that’s what i did this time.

so I will want to say this, or other people who are worried about the
additional syscalls by cycling through the index files will want to
turn it on?

run out.

okay i’ve fixed it.

currently running 0.7.10 with maxim’s dirlist patch (had some fuzz)
and your static post patch.

config is:

   server {
            listen 80;
            server_name foo.com;
            index index.php index.html;
            root /home/mike/web/foo.com/;
            include /etc/nginx/defaults.conf;
            include /etc/nginx/expires.conf;
            error_page 404 = /wordpress/index.php?q=$request_uri;
            location ~ /wordpress/admin.* {
                    auth_basic "wordpress";
                    auth_basic_user_file

/home/mike/web/foo.com/.htpasswd;
location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
}
}
location ~ .php$ {
fastcgi_pass 127.0.0.1:11000;
}
}

apparently the regex i tried earlier for admin was wrong. i had the
right idea though.

i would like to know what the behavior will be when you apply the
dirlist patch to know if i need to adjust my side or not. thanks :slight_smile:

19

yeah i’ve tried a vanilla 0.7.8 with maxim’s patch and it still isn’t
processing PHP inside of that nested location block for admin.

something is messed up. before it was working it looked like. but now
i can’t get any 0.7.8 or 0.7.10 with any patches to process that admin
block properly!

No, open_file_cache_errors has not direct relatin to index files.
It simply way to decrease number of syscalls using cache while testing
index files.

As to patch, after looking the code, I have found that EACESS at this
point should be ignored. Here is my patch (the same as Maxim’s one)
with comment. Could you or someone test English part of patch ?
