------------------------------------------------------------------------
select 选择数据库。Redis数据库编号从0~15，我们可以选择任意一个数据库来进行数据的存取
127.0.0.1:6179[4]> select 1
OK
127.0.0.1:6179[1]> keys *
keys 返回满足给定pattern的所有key
用表达式*，代表取出所有的key
--------------------------------
dbsize返回当前数据库中key的数目。
127.0.0.1:6179> dbsize
(integer) 0
127.0.0.1:6179> select 1
OK
127.0.0.1:6179[1]> dbsize
(integer) 251
------------------------
echo 在命令行打印一些内容
127.0.0.1:6179[1]> echo 'aa'
"aa"
127.0.0.1:6179[1]> echo masn
"masn"
--------------
flushdb 删除当前选择数据库中的所有key。
-------------------------
flushall
删除所有数据库中的所有key。
---------------------
del 删除一个key
------------
exists 判断一个key是否存在
------------
Get 命令用于获取指定 key 的值。如果 key 不存在，返回 nil 。如果key 储存的值不是字符串类型，返回一个错误。
