This configuration only works for the "url propre" and "url propre2" rewrite rules, when the website is in a subdirectory.
for ex. http://my.domain.zz/spip/site.html
it must be changed for other configurations.
My actual configuration is similar to this one, found on http://wiki.nginx.org/SPIP :
server {
server_name emeagwali.net www.emeagwali.net;
client_max_body_size 10m;
root /var/www/spip;
index index.php;
location / {
try_files $uri $uri/ /spip.php?q=$uri&$args;
}
location ~^/(tmp|config)/{
return 403;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php ;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
The author also gives another way to disable access to config/ and tmp/ folders.
