切换数据库写入数据（这里是实验就随便写）

使用Rump迁移

[root@ceshi-redis6 ~]# rump -from redis://Huawei12@127.0.0.1:6379/5 -to redis://Huawei12@127.0.0.1:6379/0
.Sync done

rump -from {source_redis_address} -to {target_redis_address}

{source_redis_address}
源Redis实例地址，格式为：redis://[user:password@]host:port/db，中括号部分为可选项，实例设置了密码访问时需要填写密码，格式遵循RFC 3986规范。注意用户名可为空，但冒号不能省略，例如redis://:mypassword@192.168.0.45:6379/1。db为数据库编号，不传则默认为0。
{target_redis_address}
目标Redis实例地址，格式与from相同。
