Feng Office nginx config

In case anyone needs to setup Feng Office
http://www.fengoffice.com/web/features.php (it is a web-based groupware
package, including project management, client relationship management,
email calendar, billing, financing, etc.),
over Debian 6 / Ubuntu 11.10 and Nginx 1.1.12, here is the
config file that we used:

nginx - /etc/nginx/sites-available/feng

server {
listen 80;
server_name feng.localhost;
access_log /var/log/nginx/feng.access.log;
error_log /var/log/nginx/feng.error.log;
root /var/www/fengoffice;
index index.php;
client_max_body_size 8M;
location ~ ^(?.+.php) {
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/tmp/php-fpm.socket;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$script;
fastcgi_param SCRIPT_NAME $script;
