Php – How to get php-memcached extension to work with SASL on RHEL6

memcachedPHPsasl

I have RHEL6.1 with php. I've installed libmemcached-1.0.2 from src.rpm and compiled php-memcached 2.0.0b2. If I try to setSaslAuthData('user','pass') and write something to memcached (Couchbase server) I always end up with return code 5 (WRITE FAILURE). Commenting setSaslAuthData out turns to work with default bucket. But I need to get it working with SASL. Any ideas on what's wrong with my setup?

P.S. of course binary protocol is ON

Are you sure memcached is compiled with sasl?

$ memcached -S

You should see this output if memcached wasn't compiled with SASL: "This server is not built with SASL support."

Php – memcached and PHP … massive lag with sessions

The problem is in the session.save_path syntax between memcache.so and memcached.so:

extension=memcache.so
session.save_handler = memcache
session.save_path = "tcp://127.0.0.1:11211"

vs.

extension=memcached.so
session.save_handler = memcached
session.save_path = "127.0.0.1:11211"

Note the protocol in the memcache one, no protocol in the memcached one.

Also, make sure you actually have the .so you are trying to load. They're two separate packages via apt-get or yum or whatever flavor you use.

Any breakage due to loading the wrong module or using incorrect syntax causes a 30 second load delay in php while it tries to use your session mechanism and eventually times out.

Hope that saves someone some time. ;-)
