在创建redis集群服务时，提示以下错误：

/usr/local/rvm/gems/ruby-2.4.5/gems/redis-4.1.0/lib/redis/client.rb:124:in `call': ERR Slot 0 is already busy (Redis::CommandError)
    	from /usr/local/rvm/gems/ruby-2.4.5/gems/redis-4.1.0/lib/redis.rb:3282:in `block in cluster'
    	from /usr/local/rvm/gems/ruby-2.4.5/gems/redis-4.1.0/lib/redis.rb:50:in `block in synchronize'

    	from ./redis-trib.rb:212:in `flush_node_config'
    	from ./redis-trib.rb:906:in `block in flush_nodes_config'
    	from ./redis-trib.rb:905:in `each'
    	from ./redis-trib.rb:905:in `flush_nodes_config'
    	from ./redis-trib.rb:1426:in `create_cluster_cmd'
    	from ./redis-trib.rb:1830:in `<main>'

错误提示是说：slot插槽被占用了、这是因为 搭建集群前时，以前redis的旧数据和配置信息没有清理干净。

解决方案：

用redis-cli 登录到每个节点执行  flushall  和 cluster reset  就可以了。

./redis-cli -h IP -p 端口
    flushall
    cluster reset

然后再重新执行创建集群服务命令即可：

./redis-trib.rb create --replicas 1 39.105.XX.XX:7001 114.116.XX.XX:7001 39.105.XX.XX:7001 39.105.XX.XX:7002 114.116.XX.XX:7002 39.105.XX.XX:7002
