HADOOP之环境搭建(二)

redis安装目录：/root/redis-5.0.5/utils/create-cluster

vi create-cluster

NODES=6
REPLICAS=1
创建6个节点，其实副本数1  也就是3主3从

　　

自动创建集群

[root@redis2 create-cluster]# ./create-cluster start
Starting 30001
Starting 30002
Starting 30003
Starting 30004
Starting 30005
Starting 30006

[root@redis2 create-cluster]# ps -ef | grep redis

手动创建

 redis-cli 6379.conf  --cluster create 127.0.0.1:30001 127.0.0.1:30002 127.0.0.1:30003 127.0.0.1:3004 127.0.0.1:3005 127.0.0.1:3006 --cluster-replicas 1

　　

移动槽位

redis-cli --cluster reshard 127.0.1:30001
