Redis继续学习

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/
