##1.獲取全部key
命令：keys *

127.0.0.1:6379> keys * 1) "myHash2" 2) "myHash" 3) "id" 4) "myHahs" 127.0.0.1:6379>

##2.獲取全部以某個(gè)字符開頭的key
命令：keys 字符*

127.0.0.1:6379> keys my* 1) "myHash2" 2) "myHash" 3) "myHahs" 127.0.0.1:6379>

##3.刪除某個(gè)或者某些key
命令：del key1 key2 key3 ...

127.0.0.1:6379> keys * 1) "myHash2" 2) "myHash" 3) "id" 4) "myHahs" 127.0.0.1:6379> del myHash2 id (integer) 2 127.0.0.1:6379> keys * 1) "myHash" 2) "myHahs" 127.0.0.1:6379>

##4.檢查某個(gè)key是否存在----0：不存在；1：存在

127.0.0.1:6379> keys * 1) "myHash" 2) "myHahs" 127.0.0.1:6379> exists myHash (integer) 1 127.0.0.1:6379> exists id (integer) 0 127.0.0.1:6379>

##5.對key進(jìn)行重命名

127.0.0.1:6379> keys * 1) "id" 2) "myHash" 127.0.0.1:6379> get id "100" 127.0.0.1:6379> rename id newId OK 127.0.0.1:6379> get id (nil) 127.0.0.1:6379> get newId "100" 127.0.0.1:6379>

##6.對key設(shè)置過期時(shí)間
expire key 時(shí)間(單位：秒)

127.0.0.1:6379> keys * 1) "newId" 2) "myHash" 127.0.0.1:6379> expire myHash 1000 (integer) 1 127.0.0.1:6379>

##7.查看某個(gè)key所剩的超時(shí)時(shí)間
命令：ttl key

127.0.0.1:6379> ttl myHash (integer) 889 127.0.0.1:6379>

##8.獲取指定key的類型

127.0.0.1:6379> keys * 1) "newId" 2) "myHash" 127.0.0.1:6379> type newId string 127.0.0.1:6379>
