前言:Redis的测试有一些讲究,如果你是先安装集群再来测试会出现很多意想不到的问题。单个redis-server测试很简单 就是照着API搞就行,但是如果是先搭建集群环境而使用集群节点(单个IP和端口)来操作就不适用了。集群的特点就是分担服务端的压力,此时采用Redis一般的操作API就不适用了,因为集群节点会发生转移(MOVED)到另一个节点上去,所以API操作要对应模式——集群应当使用与cluster API进行操作。Redis访问是建立的c/s模式的socket连接,所以不同的节点要么主机(Host)IP不同要么端口(port)不同,redis以此绑定(bind)IP和port (ip:port)。

1)cluster环境下redis的slave不接受任何读写操作,
2)client端不支持keys批量操作,不支持select dbNum操作,只有一个db:select 0
3)JedisCluster 的info()等单机函数无法调用,返回(No way to dispatch this command to Redis Cluster)错误,.

因为redis默认没有设置密码,所以在访问的时候可以不设置auth.若要使用密码方式访问,需要在redis.conf中设置requirepass yourpass.

MOVED indicates that you're using Redis Cluster. ShardedJedis is not for Redis Cluster, so you should use JedisCluster instead. 不应该调用集群节点,API调用方式错误。
