port 11211 (memcached default) not open

[Danny Trinh]

Hello group,
I use nginx-0.8.31 and do try the memcached config from
http://lserinol.blogspot.com/2009/03/speeding-up-your-nginx-server-with.
html.

location ~* \.(jpg|png|gif)$ {
access_log   off;
expires      max;
add_header   Last-Modified "Thu, 26 Mar 2000 17:35:45 GMT";
set $memcached_key $uri;
memcached_pass     127.0.0.1:11211;
error_page         404 = /fetch;
}

But when I do "netstat -an", I didn't see port 11211 listening. Am I
missing some thing?

Thanks,
