What's the simplest way to serve php files through an alias?

Server NGINX
1

we have a very simple configuration.

server block with location block

php is served through fastcgi and works fine

would like to add something like this:

location /nameofalias/
{
alias /usr/local/nameofalias;
}

but it does not seem to work, static files load fine.

the php location block is like this and works fine for the main location
block of “location /”

    location ~ .php$
    {
            include fcgi;
            fastcgi_pass 127.0.0.1:9000;
    }

what else is needed?

This is now how alias is supposed to be used. In fact you’re using
alias like a root directive. Using alias is for when you want to use a
certain base directory and don’t want the URI to reflect that.

location /foo {
alias /var/www/nginx-default/barz;
}

Request for /foo/xpto.png is translated to

/var/www/nginx-default/barz/xpto.png

but it does not seem to work, static files load fine.

the php location block is like this and works fine for the main
location block of “location /”

location ~ .php$
{
include fcgi;
fastcgi_pass 127.0.0.1:9000;
}

You should have a fastcgi_pass directive where you want the PHP files
to be handled.

Also you need to escape the “.” as in

location ~ .php$ {
(…)
}

Thanks,

I tried it using “root” in the location, still no luck.

Here’s my config (the parts that matter), the location /nagios/ is
what’s
not working. What am I doing wrong? Thanks

http
{
root /var/www/html;
server
{
listen 10.0.1.163;
server_name dev.testsite.com;
location /nagios/
{
root /usr/local/nagios/share;
index index.php;
}
location /
{
index index.php;
error_page 404 = @joomla;
log_not_found off;
}
location @joomla
{
rewrite ^(.*)$ /index.php?q=$1 last;
}

    location ~ \.php$
    {
            include fcgi;
            fastcgi_pass 127.0.0.1:9000;
    }

}

}

“not working”?

  • What are you expecting?
  • What are you getting?

         index index.php;
     }

as this one is located in different root path, you need additional php
block

location ~ ^/nagios/.*.php$ {
…
}

Thanks for the advice. When I do it this way, I get an error (nginx
error
log):

2010/10/03 00:27:33 [error] 20239#0: *6447
“/usr/local/nagios/share/nagios/index.php” is not found (2: No such file
or
directory)

so you can see that nginx is adding /nagios/ to the end of the root
directory and so the file is not found (generating a 404 on the
browser).

What would be the correct way to address this issue?

Thank you for your suggestion, I remember the vigorous discussion that
took
place regarding this issue, in this particular case, this is a test /
development system so I’m not as concerned as I normally would be.

In our production environment, things are a bit more rigid.

btw, when I change the same configuration to alias and try to access
/nagios/, I get this error:

2010/10/03 00:36:06 [error] 7399#0: *6485 directory index of
“/usr/local/nagios/share” is forbidden

when I go to /nagios/index.php, I don’t get an error in the log, but an
error in the browser, that says:
Oops! This link appears to be broken.

For security reasons I suggest you constrain which exact locations can
be used for FastCGI. Using a generic regex for any file with php
extension opens a big security hole. This was discussed not long ago
on the list.

Instead you should enumerate which files are to be handled by FastCGI
and return a 404 for every other file that is not enumerated. E.g.,

location ~* ^/index.php$ {
include fcgi;
fastcgi_pass 127.0.0.1:9000;
}

And put at the end of the config file:

Any other attempt to access PHP files returns a 404.

location ~* ^.+.php$ {
return 404;
}

Using alias:

    location /nagios {
            alias /usr/local/nagios/share;
            index index.php;
    }

Request for nagios gets translated in /usr/local/nagios/share/index.php;

use alias.

location ~ ^/nagios/(.*.php)$ {
alias /usr/local/nagios/share/$1;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;

location = /nagios {
rewrite ^ /nagios/ permanent;
}
location /nagios/ {
index index.php;
alias /usr/local/nagios/share/;
}

Thank you all for your responses.

I believe that the missing element in my case was:

alias /usr/local/nagios/share/$1;

in the nagios php processing location, I wasn’t aware that I would have
to
specify it there as well, but it makes sense now.

Thanks!
