Hi All,

Can anyone tell me how to configure redis cluster? I installed redis
2.6 version. I want to use two writable master servers and replicate
them each other.

Best regards.

There's no cluster in 2.6 yet (or did I miss something)?

I see. Maybe you can tell me how to configure multiple site replication with
redis 2.4 current stable release. I have two hash slots on different sites
and i have one master server on both sites. They are working fine
separately but i want to replicate two master servers each other. Is there
any solution to make this?

Short answer: no.

Longer answer: multi-master replication without Redis cluster doesn't
work. Redis cluster is in unstable right now, but isn't targeted to be
finished until the end of the year (if I remember correctly).

redis. Maybe redis developers will give us official comment to understand
it deeply.
system, but redis isn't ready yet.

I think you have a wrong idea about what the Redis Cluster will be.
It will not support master-master replication.

The migrate command is about resharding (rebalancing) the cluster,
not master-master replication.

You can find more information about the Redis Cluster here:
http://redis.io/presentation/Redis_Cluster.pdf

It is clearly stated that "there is no merge, nor application-side
inconsistency resolution"

While some related commands have been added in Redis 2.6,
that's a fact Redis Cluster has not been delivered yet.

If you really need master-master replication capabilities, I suggest you
turn
to another storage solution. Very few NoSQL engines provide this
capability though (CouchDB does, to some extent).

Some relational storage engines provide it as well.
Percona clustering solution (based on Galera) comes to my mind:

Didier.

Best regards.

I have one more question about redis. Is there any way to redirect ke-value
pairs to another node when added? I tried to use redis-cli monitor command
to get set processes but it didn't enogh for me to send them to another
redis node. I want to send them without master slave relationship.

Best regards.
