Configuration nginx + php-fpm

Here is an example of a working configuration. This configuration suggests that php-fpm works through socket:

 # ....
    sendfile on;     
   keepalive_timeout  65;     
   tcp_nodelay  on;     
   gzip	on;     
   gzip_min_length	1100;     
   gzip_disable "MSIE [1-6]\.(?!.*SV1)";     
   gzip_proxied	any;     
   gzip_comp_level	4;     
   gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;    
   gzip_vary  on;     
 # ....
