生成redis实例
进入管理节点pod中

redis-cli -h 172.20.69.232 -p 7001 --cluster create 172.20.69.232:7001 172.20.69.232:7002 172.20.69.233:7003 172.20.69.233:7004 172.20.69.234:7005 172.20.69.232:7006 --cluster-replicas 1 --cluster-yes

生成集群即可

redis-cli -h 172.20.69.232 -p 7001 config set requirepass sco2018cass   #密码可以根据自己改

redis-cli -h 172.20.69.232 -p 7002 config set requirepass sco2018cass

redis-cli -h 172.20.69.232 -p 7003 config set requirepass sco2018cass

redis-cli -h 172.20.69.232 -p 7004 config set requirepass sco2018cass

redis-cli -h 172.20.69.232 -p 7005 config set requirepass sco2018cass

 redis-cli -h 172.20.69.232 -p 7006 config set requirepass sco2018cass

 redis-cli -h 172.20.69.232 -p 7001 -a sco2018cass cluster info 查询集群信息

 
 
注意如果需要，redis集群有密码要求，需要改动一个地方
 
command: redis-server --appendonly yes --cluster-enabled yes --cluster-config-file /conf/nodes.conf --cluster-announce-ip 172.20.69.232 --cluster-announce-port 7001 --cluster-announce-bus-port 17001 --requirepass sco2018cass --masterauth sco2018cass
redis-server的启动命令加上参数就好了，不然会报错从库数据同步失败
