Nginx and memcached

Server NGINX
1

Hi folks!

I try to use nginx with memcached with less success, maybe this is just
a well known issue but i did not find anything in google:

config:

    location / {

        set  $memcached_key  $uri;
        memcached_pass    127.1.0.1:11212;
        default_type      text/html;
        error_page        404 = /fallback;

        location = /fallback {
          root   /usr/local/www/nginx-dist/;
          index  index.html index.htm;
        }

    }

error log in debug mode:

2008/07/20 13:52:43 [error] 73685#0: *5 memcached sent invalid response:
“marugoto_end” while reading response header from upstream, client:
xx.xx.116.179, server: zen.xx.xx.hu, request: “GET / HTTP/1.1”,
upstream: “memcached://127.1.0.1:11212”, host: “zen.xx.xx.hu”

test:

nc -v 127.1.0.1 11212

Connection to 127.1.0.1 11212 port [tcp/*] succeeded!
marugoto_end

any suggestion?

thanx in advance

Your memcached server isn’t memcached. Probably it’s something
locally modified, or something completely different. You should
use memcached instead or ask author of modifications you use to
revert incompatible protocol changes.

Hi!

I think it is…

[root@mimas ~]# which memcached
/usr/local/bin/memcached
[root@mimas ~]# pkg_info |grep memcached

heh the memcached has a console or something listening on 11212 and the
proper for nginx is 11211

thank you Maxim!

Ah, I see. It’s repcached replication patches, 11212 - default
replication port.

Memcached has no “marugoto_end” initial message. Probably
something different listens on 11212 port.
