Moxi speaks the memcached protocol, so it can work with both memcached servers and Couchbase servers.
When used with Couchbase, Moxi is started with a REST/URL that describes the Couchbase cluster configuration, and Moxi uses vbucket hashing to determine which key-value items live on which servers.
When used with standard, classic memcached, Moxi should be started with different command-line parameters that will make Moxi use libmemcached (ketama) hashing. In particular, Moxi will take a different cluster or -z command-line flag, like...
./moxi -z LISTEN_PORT=MEMCACHED_HOST1[:PORT1][,MEMCACHED_HOSTN[:PORTN]]
The memcached PORT's default to 11211. For example, below, moxi will
listen on port 11811 and use ketama hashing against a server-list of
./moxi -z 11811=mc1,mc2 ./moxi -z 11811=mc1:11211,mc2:11211
You may also move the -z cluster configuration into a separate file, by specifying either an absolute or relative path...
./moxi -z ./relative/path/to/cluster/config_file ./moxi -z /absolute/path/to/cluster/config_file
The contents of the config_file should look like...
