部署redis集群(单机)

docker run -d --net host --name redis-cluster-node0 redis \
redis-server --cluster-enabled yes --protected-mode no --bind 0.0.0.0 --port 7000

docker run -d --net host --name redis-cluster-node1 redis \
redis-server --cluster-enabled yes --protected-mode no --bind 0.0.0.0 --port 7001

docker run -d --net host --name redis-cluster-node2 redis \
redis-server --cluster-enabled yes --protected-mode no --bind 0.0.0.0 --port 7002

--net host相当于在本机监听，否则redis实例之间无法相互发现

docker stop redis-cluster-node0 && \
docker stop redis-cluster-node1 && \
docker stop redis-cluster-node2

docker rm redis-cluster-node0 && \
docker rm redis-cluster-node1 && \
docker rm redis-cluster-node2

查看集群信息

1. redis命令 cluster nodes
2. redis-cli --cluster info host:port

非 --net host

$PUBLIC_IP 为主机的公网ip

docker stop redis-cluster2-node1 && \
docker stop redis-cluster2-node2


docker rm redis-cluster2-node0 && \
docker rm redis-cluster2-node1 && \
docker rm redis-cluster2-node2


docker run -d --name redis-cluster2-node0 \
-p 8000:6379 -p 18000:16379 \
redis redis-server --cluster-enabled yes \
--cluster-announce-ip $PUBLIC_IP --cluster-announce-port 8000 --cluster-announce-bus-port 18000

docker run -d --name redis-cluster2-node1 \
-p 8001:6379 -p 18001:16379 \
redis redis-server --cluster-enabled yes \
--cluster-announce-ip $PUBLIC_IP --cluster-announce-port 8001 --cluster-announce-bus-port 18001

docker run -d --name redis-cluster2-node2 \
-p 8002:6379 -p 18002:16379 \
redis redis-server --cluster-enabled yes \
--cluster-announce-ip $PUBLIC_IP --cluster-announce-port 8002 --cluster-announce-bus-port 18002

redis-cli --cluster create $PUBLIC_IP:8000 $PUBLIC_IP:8001 $PUBLIC_IP:8002
