redis数据类型

总共五种数据类型：

 

1、Strings - 字符串

127.0.0.1:6379> set name "zhaoja"
OK
127.0.0.1:6379> get name
"zhaoja"

 

2、Hashes - 哈希值

 

 

 

3、Lists - 列表
Redis的列表是简单的字符串列表，排序插入顺序。可以添加元素到Redis列表的头部或尾部

127.0.0.1:6379> lpush nlist zhaoja
(integer) 1
127.0.0.1:6379> lpush nlist zhaoja2
(integer) 2
127.0.0.1:6379> lrange nlist 0 10
1) "zhaoja2"
2) "zhaoja"

　　

 

 

4、Sets - 集合
Redis集合是字符串的无序集合

127.0.0.1:6379> sadd nalist zhaoja1
(integer) 1
127.0.0.1:6379> sadd nalist zhaoja2
(integer) 1
127.0.0.1:6379> sadd nalist zhaoja3
(integer) 1
127.0.0.1:6379> smembers nalist
1) "zhaoja3"
2) "zhaoja2"
3) "zhaoja1"

　　

 

5、集合排序
Redis的集合排序类似于Redis集合，字符串不重复的集合

127.0.0.1:6379> zadd namlist 0 zhaoja1
(integer) 1
127.0.0.1:6379> zadd namlist 0 zhaoja2
(integer) 1
127.0.0.1:6379> zadd namlist 0 zhaoja3
(integer) 1
127.0.0.1:6379> zadd namlist 0 zhaoja4
(integer) 1
127.0.0.1:6379> zrangebyscore namlist 0 1000
1) "zhaoja1"
2) "zhaoja2"
3) "zhaoja3"
4) "zhaoja4"
