- 建立redis集群
docker exec -it redis-7001 bash
redis-cli --cluster create 10.211.55.6:7001 10.211.55.6:7002 10.211.55.6:7003 10.211.55.6:7004 10.211.55.6:7005 10.211.55.6:7006 --cluster-replicas 1

- 測試
#隨便進入一個redis容器
docker exec -it redis-7001 /bin/bash
#使用redis-cli cluster方式連接，然后使用get set測試就可以了
redis-cli -c -h 10.211.55.6 -p 7001
#獲取集群信息
cluster info
#獲取群節點信息
cluster nodes
#主節點宕機，slave會自動提升為master，主節點恢復后會變成slave
