Hi I'm having trouble setting up my Rails project on my server because apache keeps complaining

DalliError: No server available.

I installed memcached on my ubuntu machine, but it still doesn't work. My rails project also has config.cache_store = :dalli_store, 'localhost:11211', { :namespace => "production" } in environments/production.rb. How would I debug this?

My log shows before each request:

localhost:11211 failed (count: 6)
DalliError: No server available

telnet to 11211:

    root@s2:/usr/local/www/production/current/log# telnet localhost 11211
    Trying 127.0.1.1...
    telnet: Unable to connect to remote host: Connection refused

I had the same problem. First I installed memcached as a gem gem install memcached and got the error "DalliError: No server available"

Then I installed memcached by doing sudo apt-get install memcached. It works fine now.
