## redis
redis是一个开源的支持多种数据类型的key=>value的存储数据库。支持字符串、列表、集合、有序集合、哈希五种类型
图片过大,请下载到本地打开

### redis 和memcache区别
1. Redis不仅仅支持简单的k/v类型的数据,同时还提供list,set,hash等数据结构的存储。
2. Redis支持数据的备份,即master-slave模式的数据备份。
3. Redis支持数据的持久化,可以将内存中的数据保持在磁盘中,重启的时候可以再次加载进行使用。
### redis五种类型
#### 字符串
> set 、get、append、strlen
### 列表
> lpush lpop rpop rpush llen lrem lset
#### 集合
> sadd、smembers、sdiff、spop 、srem、scard
#### 有序集合
> zadd、 zcount、zrem、zrank、
#### 哈希
> hset、hget、hmget、hmset、hkeys、hlen、hsetnx、hvals
