Hello to all nginx & php gurus

I'm installing dotclear (a blogging software written in PHP) on my debian, and I have a hard time configuring nginx, php5-fpm and php so that :

1. I can use PATH_INFO url rewriting since I'm following Tim Berneer's Lee advice that urls should'nt expose what particular technology you use right now http://www.w3.org/Provider/Style/URI.html
   


2. satic-files are not parsed by PHP since it's terribly insecure to let example.org/uploads/image.jpg/index.php to be sent to PHP


3. have a root location that just works example.com should be rewritten to something like example.com/index.php?start

It seems that until now, I have to choose 2, that's why I'm asking for help here.

So here is my current /etc/nginx/nginx.conf

server 
 server_name articles.eloge-de-la-folie.fr;
 root /srv/data1/articles.eloge-de-la-folie.fr ;

index index.php?start ;
location / 
 try_files $uri $uri/ @pathinfo ;
 #try_files $uri $uri/ /index.php$uri?$args;

# Pretty URLs in dotclear
# activate PATH_INFO urls in /admin/blog_pref.php
location @pathinfo
rewrite ^ /index.php$uri?$args last;

location = /
rewrite ^ /index.php?start last;

location ~ ^(.+.php)(/.*)?$
include fastcgi_params_pathinfo ;

I put everything fastcgi related in a separate /etc/fastcgi_params_pathinfo config file

fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

#fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;

fastcgi_param HTTPS $https;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;


# this is what I changed
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Also in /etc/php5/fpm/pool.d/www.conf, I made sure to uncomment this

security.limit_extensions = .php ;

What happen currently ?
- example.com/index.php and example.com/post/test are passed to the php interpretor and work
- example.com/css/style.css are not passed to php and works
- but when I go to example.com, the index.php is just downloaded, not interpreted.

My location = / configuration here  is apparently never matched :(

Thanks in advance,

Jean-Michel

Here you'll find help:
http://yeti.selfip.net/cms/index.php/post/2013/10/26/Configure-PHP-with-Nginx-only-once-for-several-aliases
And keep this too:
fastcgi_param SCRIPT_FILENAME $request_filename;

It's not very elegant, but I don't have better to provide :(
One note, though: When configuring dotclear to use PATH_INFO, you still have index.php inside, just as in the URL above (which is hosted by dotclear). There may be a way around this with URL rewrites...

I'm pretty sure this is the problem

index index.php?start ;
location / 
 try_files $uri $uri/ @pathinfo ;
 #try_files $uri $uri/ /index.php$uri?$args;

Nginx will never find a file with the filename "index.php?start" on the hard drive. In your location / block you are saying, try to find the URI, which is just /, which is just the root directory, and it finds that.

My location = / configuration here is apparently never matched :(

It is matched, just the first one is matched and not the second one.
Remove the first location / block and the index index.php?start (because I think the latter will never work).
