Not working in Rails 3.0 about dalli HOT 10 CLOSED

memcache deamon is running like this:
$ ps ax | grep memcache
1036 ? Sl 0:00 /usr/bin/memcached -m 64 -p 11211 -u nobody -l 127.0.0.1

from dalli.

Ok, now is working - after configuring it like this:
config.cache_store = :dalli_store, "127.0.0.1:11211"

Shouldn't it be handled automatically?
Or what is the proper way of launching memcached, to have it working without specyfing this server configuration?

I suspect you're on OSX. OSX treats localhost as an IPv6 address. You told memcached to bind to an IPv4 address.

No, it's debian squeeze, but I get what you mean.
Thanks

What version of memcached ("memcached -h | head -1")? That stack looks like you are running 1.2.x.

from dalli.

dalli (1.0.1) is broken under Ubuntu and memcached 1.2.2...

But it works OK on OSX and memcached 1.2.8...

Mac OS-X (10.6.6):

Ubuntu Jaunty comes with memcached 1.2.x, which is not supported. You can stop posting the same comment now. :-)

I have just installed the latest stable memcached 1.4.5 on Ubuntu. Something is fucked up. memcached quits with segmentation fault (sic!) after the following command: ruby -rdalli -e "Dalli::Client.new('127.0.0.1:11211').flush"

from dalli.

Dalli only supports non-crashing versions of memcached. :-)

I know this issue has been closed, but I thought I'd add a comment in case someone else runs into this. My production server is running Ubuntu Lucid Lynx (10.04 LTS) with ruby 1.9.2p180, Rails 3.1, Passenger 3.0.7, memcached 1.4.2 (confirmed with memcached -h | head -1) and dalli 1.1.2. The localhost name resolved to IPv4. However, I kept seeing "localhost:11211 failed", along with "localhost:11211 is down".

I took morgoth's comment and specified "127.0.0.1:11211" and the problem went away.
