1、Redis一共16个数据库
# Set the number of databases. The default database is DB 0, you can select # a different one on a per-connection basis using SELECT <dbid> where # dbid is a number between 0 and 'databases'-1 databases 16
1、切换数据库 (切换到第6个库)
127.0.0.1:6379[7]> select 6 OK 127.0.0.1:6379[6]>
2、求有多少个数据(DBSIZE)以及那些数据(KEYS *)
127.0.0.1:6379> DBSIZE (integer) 3 127.0.0.1:6379> key * (error) ERR unknown command 'key' 127.0.0.1:6379> KEYS * 1) "k1" 2) "k3" 3) "k2"
3、清空(FLUSHDB)清空所有库(FLUSHALL)
4、其他指令参考http://redisdoc.com/
