Docker中Redis三主三从集群安装步骤

#创建网络

docker network create redis --subnet 172.38.0.0/16

docker network inspect redis   #查看网络信息

for port in $(seq 1 6); \

#创建集群

# 进去其中一个节点

docker exec -it redis-1 /bin/sh  

#创建集群
redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 172.38.0.14:6379 172.38.0.15:6379 172.38.0.16:6379 --cluster-replicas 1

#进入集群
[root@iZhp370tnu2qiflovwb8evZ ~]# docker exec -it redis-1 /bin/sh
/data # redis-cli -h redis-3

#查看集群信息
redis-3:6379> cluster info

#进入集群
redis-cli -c
