先决条件
装置docker、docker-compose.
docker-compose.yml文件

批改Redis配置文件

咱们先下载Redis的官网配置文件，下载地址：http://download.redis.io/redis-stable/redis.conf

批改局部配置
cluster-enabled yes #启用集群bind 0.0.0.0    #默认127.0.0.1只能本地拜访，改为0.0.0.0，所有主机都能拜访
通过docker-compose装置redis节点
在docker-compose.yml所在目录下执行如下命令：docker-compose up -d.执行后会运行三个redis节点,别离为redis-node01、redis-node02、redis-node03.
注：此时的三个redis节点是互相独立的，还不是集群。
将多个node节点组成集群

进入任意一个节点容器，执行一下命令，ip地址替换成你本身的节点IP,IP是生成的三个节点的容器外部IP，能够通过执行`docker
inspect docker容器id | grep Address`查看容器IP信息

redis-cli --cluster create 172.18.0.4:6379 172.18.0.3:6379 172.18.0.2:6379 -- cluster-replicas 0

在节点容器内输出redis-cli -c，查看集群信息cluster info,

cluster_state:ok  #<---如果此处为ok阐明集群创立胜利cluster_slots_assigned:16384cluster_slots_ok:16384cluster_slots_pfail:0cluster_slots_fail:0cluster_known_nodes:3cluster_size:3cluster_current_epoch:3cluster_my_epoch:1cluster_stats_messages_ping_sent:218cluster_stats_messages_pong_sent:217cluster_stats_messages_sent:435cluster_stats_messages_ping_received:215cluster_stats_messages_pong_received:218cluster_stats_messages_meet_received:2cluster_stats_messages_received:435

此时通过set设置key-value的时候，就会将key-value增加到3个不同的节点中去了，三个节点的总key数就是全量key,每个节点仅存储各自的key汇合，然而在集群不同节点都能够get到其余节点key的value值。
