1、关闭cluster全部节点
2、删除所有nodes.conf文件
3、开启全部节点
4、依次flushall
5、重建集群即可

redis集群启动失败案例
部署Redis分布式集群时，出现了如下错误: moguang@ubsvr13:/opt/redis-unstable/src$ ./redis-trib.rb create >>> Creating cluster Connecting to node : OK Connecting to node : OK Connecting to node : OK >>> Performing hash slots allocation on nodes... Using masters: M: 225b7f54c67483f71955db78312a90c67941fff0 slots:- ( slots) master M: bca62c53e7f50d7c83dd418ed23e08fb8a4e9bb5 slots:- ( slots) master M: 47483c65a705025aab28ee74da210a2dce41bc41 slots:- ( slots) master Can I set the above configuration? (type 'yes' to accept): yes /usr/lib/ruby/gems//lib/redis/client.rb::in `call': ERR Slot 16011 is already busy (Redis::CommandError) /lib/redis.rb::in `method_missing' /lib/redis.rb::in `synchronize' :in `mon_synchronize' /lib/redis.rb::in `synchronize' /lib/redis.rb::in `method_missing' :in `flush_node_config' :in `flush_nodes_config' :in `each' :in `flush_nodes_config' :in `create_cluster_cmd' :in `send' 经检查，这是由于上一次配置集群失败时留下的配置信息导致的。 只要把redis.conf中定义的 cluster-config-file 所在的文件删除，重新启动redis-server及运行redis-trib即可。
