1. 主机配置：
10.21.14.164,10.21.14.165，10.21.14.166
2. 端口配置
6381,6382
3. 6381的redis.conf配置
port 6381
protected-mode no
pidfile /var/run/redis_6381.pid
appendonly yes
cluster-enabled yes
cluster-config-file nodes-6381.conf
cluster-node-timeout 15000
4. 6382的redis.conf配置
port 6382
protected-mode no
pidfile /var/run/redis_6382.pid
appendonly yes
cluster-enabled yes
cluster-config-file nodes-6382.conf
cluster-node-timeout 15000
5. 三台主机分别新建目录并将redis.conf放入
/app/redis/cluster/6381/data, /app/redis/cluster/6382/data
6. 三台主机启动Redis
docker run -v /app/redis/cluster/6381/data/:/data --privileged=true --net host --name redis-6381 -d redis:latest redis-server /data/redis.conf
docker run -v /app/redis/cluster/6382/data/:/data --privileged=true --net host --name redis-6382 -d redis:latest redis-server /data/redis.conf
7. 任选一个redis使用redis-cli创建集群
docker exec -it redis-6381 redis-cli --cluster create 10.21.14.164:6381 10.21.14.164:6382 10.21.14.165:6381 10.21.14.165:6382 10.21.14.166:6381 10.21.14.166:6382 --cluster-replicas 1
选择yes自动创建集群
