How to use fastcgi_index?

Server NGINX
1

Hi.

In my nginx.conf (of nginx 0.6.31, part of Sun’s CoolStack 1.3.1), I
have:

    location ~ \.php$ {
        root           /data/www;
        fastcgi_pass   127.0.0.1:65505;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME

/data/www$fastcgi_script_name;
include fastcgi_params;
}

In /data/www, I have a “pi” directory, containing:

–($ /opt/coolstack/nginx/conf)-- ls -l /data/www/pi
total 1
-rw-r–r-- 1 webservd webservd 26 Nov 4 13:49 index.php
–($ /opt/coolstack/nginx/conf)-- cat /data/www/pi/index.php

<?php phpinfo(); # EOF # When I now call http://$server/pi/, I'm shown the directory index of the "pi" directory (because I have "autoindex on;"). What would be the proper way to have nginx "show" the index.php, if there's one and if http://$server/$dir/ is invoked? (I don't want to see the source code of index.php, I want to have that interpreted by PHP.) Do I have to add it to the "index" direcetive, like so? location / { root /data/www; index default.htm index.html index.htm index.php; } This works, but is that the way it's supposed to be done? But also adding "fastcgi_index index.php;" to the "location / { … }" statement doesn't make nginx call PHP with the index.php. Hm. I don't think that I understand what fastcgi_index should be doing. I now changed the nginx.conf to contain: http { # … server { # … location / { root /data/www; index default.htm index.html index.htm index.php; } location ~ \.php$ { root /data/www; fastcgi_pass 127.0.0.1:65505; fastcgi_index SCHNISMindex.php; fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name; include fastcgi_params; } } } Effect: When http://$srv/$dir/ is invoked by the browser, whatever is in index.php is feed to PHP and shown to the browser. Nice — But why is that so? I would have thought, that because of the (in this case purposely) mis-configured fastcgi_index parameter, it shouldn't have worked. I would have thought, that a "SCHNISMindex.php" would have been passed to PHP. Why is that not so? What does fastcgi_index do? I have read (and obviously not understood) http://wiki.codemongers.com/NginxHttpFcgiModule#fastcgi_index of course :) Thanks a lot, Mchael -- -- GMX Download-Spiele: Preizsturz!

PHP with the index.php.
server {
fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;

of course :slight_smile:

The index directive looks up local filesystem for index files,
so in following configuration

 location / {
     root   /data/www;
     index  index.php;
 }

 location ~ \.php$ {
     fastcgi ...
 }

the index sees /data/www/index.php and does internal redirect to
/index.php,
so the request goes to “location ~ .php$” and is passed to fastcgi.

However, if fastcgi server is remote one, and nginx has no access to its
filesystem, then index has no idea about remote index files. The
fastcgi_index
should help here: it simply adds its value to any /dir/, i.e. it maps
/dir/ to /dir/index.php.

 location ~ (\.php|/)$ {
     fastcgi_index  index.php;
     fastcgi_param  SCRIPT_FILENAME  /data/www$fastcgi_script_name;
 }

}
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /data/www$fastcgi_script_name;
}

Let me see, if I got this right - fastcgi_index is, in my setup,
where nginx and the fastcgi server share filesystems, in such
a setup fastcgi_index doesn’t do anything at all and can be
omitted.

Correct?

Yes, fastcgi_index inside “location ~ .php$” does not anything because
he location matches .php only files, but not “…/” requests.

Also, note that “index” can test several index files (PHP, HTML, etc) on
local filesystem, but “fastcgi_index” can add the single index file only
in $fastcgi_script_name variable to pass it to fastcgi server.
