集群的坑
You can't have keys in a DB different than DB 0 when in Cluster mode. Exiting.
    aof文件修改一个名字

(error)LOADING Redis is loading the dataset in memory
    清空flushdb

Waiting for the cluster to join 一直等待
    打开各自端口+10000的redis端口总线
    自己服务的bind设置为公网ip再启动redis-server
    src/redis-cli --cluster create 10.10.89.43:6379 10.10.89.45:6379 10.10.93.247:6379 -a libo510723

(error) MOVED 866 10.10.89.43:6379
    redis-cli 加上 -c 参数就可以在其他机器get key了

添加节点（把新节点添加到已存在的一个节点上即可）
    src/redis-cli --cluster add-node 10.10.93.247:6380 10.10.89.43:6379
