./redis-cli --cluster create 192.168.0.80:7000 192.168.0.80:7001 192.168.0.80:7002 192.168.0.80:7003 192.168.0.80:7004 192.168.0.80:7005 --cluster-replicas 1

View the cluster status

cat nodes.conf

Configuration is complete

 Using client   Using a cluster requires adding -c
./redis-cli -h 127.0.0.1 -p 7000 -c

Be careful ： The firewall and server access rules need to be added 7000 17000 port , The same is true for several other ports
