1. Create new folder 'cluster' under redis-64.3.0.503. Create subfolder 7001 -7006 under the folder 'cluster'. Copy redis.windows.conf.
redis
  |---7001/redis.conf
  |---7002/redis.conf
  |---7003/redis.conf
  |---7004/redis.conf
  |---7005/redis.conf
  |---7006/redis.conf

There are 3 master nodes and 3 slave nodes.

2. Update configuration in redis.conf
        port 7001
        cluster-enabled yes

cluster-config-file nodes.conf

3. Download Ruby from http://rubyinstaller.org/downloads/.
Install redis dependency under ruby: gem install redis

4. Startup redis：
    cluster\7001>..\..\redis-server.exe redis.conf
    cluster\7002>..\..\redis-server.exe redis.conf
    cluster\7003>..\..\redis-server.exe redis.conf
    cluster\7004>..\..\redis-server.exe redis.conf
    cluster\7005>..\..\redis-server.exe redis.conf
    cluster\7006>..\..\redis-server.exe redis.conf

5. Setup cluster:
D:\Tools\ruby-2.3.3-x64-mingw32>bin\ruby.exe ..\redis-3.2.8\src\redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006

Done.

Java client example:

public static void main(String[] args) throws Exception {
Set<HostAndPort> nodes = new HashSet<HostAndPort>();
nodes.add(new HostAndPort("127.0.0.1", 7001));
nodes.add(new HostAndPort("127.0.0.1", 7002));
nodes.add(new HostAndPort("127.0.0.1", 7003));
nodes.add(new HostAndPort("127.0.0.1", 7004));
nodes.add(new HostAndPort("127.0.0.1", 7005));
nodes.add(new HostAndPort("127.0.0.1", 7006));
JedisCluster cluster = new JedisCluster(nodes );
cluster.set("a", "1");
System.out.println(cluster.get("a"));
cluster.close();
}
