前言

最近在学习Redis相关知识，看了阿里的redis开发规范，以及Redis开发与运维这本书。分使用规范、有坑的命令、项目实战操作、运维配置四个方向，整理了使用Redis的21个注意点，希望对大家有帮助，一起学习哈

：「捡田螺的小男孩」

1、Redis的使用规范

1.1、 key的规范要点

我们设计Redis的key的时候，要注意以下这几个点：

❝

以业务名为key前缀，用冒号隔开，以防止key冲突覆盖。如，live:rank:1

确保key的语义清晰的情况下，key的长度尽量小于30个字符。

key禁止包含特殊字符，如空格、换行、单双引号以及其他转义字符。

Redis的key尽量设置ttl，以保证不使用的Key能被及时清理或淘汰。

❞

1.2、value的规范要点

Redis的value值不可以随意设置的哦。

「第一点」，如果大量存储bigKey是会有问题的，会导致慢查询，内存增长过快等等。

如果是String类型，单个value大小控制10k以内。
如果是hash、list、set、zset类型，元素个数一般不超过5000。

「第二点」，要选择适合的数据类型。不少小伙伴只用Redis的String类型，上来就是set和get。实际上，Redis 提供了「丰富的数据结构类型」，有些业务场景，更适合hash、zset等其他数据结果。

「反例：」

实际业务开发中，同时我们要合理评估Redis的容量，避免频繁set覆盖，导致设置了过期时间的key失效。新手小白容易犯这个错误。

3.4 缓存穿透问题

先来看一个常见的缓存使用方式：读请求来了，先查下缓存，缓存有值命中，就直接返回；缓存没命中，就去查数据库，然后把数据库的值更新到缓存，再返回。

「缓存穿透」：指查询一个一定不存在的数据，由于缓存是不命中时需要从数据库查询，查不到数据则不写入缓存，这将导致这个不存在的数据每次请求都要到数据库去查询，进而给数据库带来压力。

❝

通俗点说，读请求访问时，缓存和数据库都没有某个值，这样就会导致每次对这个值的查询请求都会穿透到数据库，这就是缓存穿透。

❞

缓存穿透一般都是这几种情况产生的：

「业务不合理的设计」，比如大多数用户都没开守护，但是你的每个请求都去缓存，查询某个userid查询有没有守护。
「业务/运维/开发失误的操作」，比如缓存和数据库的数据都被误删除了。
「黑客非法请求攻击」，比如黑客故意捏造大量非法请求，以读取不存在的业务数据。

「如何避免缓存穿透呢？」 一般有三种方法。

如果是非法请求，我们在API入口，对参数进行校验，过滤非法值。
如果查询数据库为空，我们可以给缓存设置个空值，或者默认值。但是如有有写请求进来的话，需要更新缓存哈，以保证缓存一致性，同时，最后给缓存设置适当的过期时间。（业务上比较常用，简单有效）
使用布隆过滤器快速判断数据是否存在。即一个查询请求过来时，先通过布隆过滤器判断值是否存在，存在才继续往下查。

❝

布隆过滤器原理：它由初始值为0的位图数组和N个哈希函数组成。一个对一个key进行N个hash算法获取N个值，在比特数组中将这N个值散列后设定为1，然后查的时候如果特定的这几个位置都为1，那么布隆过滤器判断该key存在。

❞

3.5 缓存雪奔问题

「缓存雪奔：」 指缓存中数据大批量到过期时间，而查询数据量巨大，请求都直接访问数据库，引起数据库压力过大甚至down机。

缓存雪奔一般是由于大量数据同时过期造成的，对于这个原因，可通过均匀设置过期时间解决，即让过期时间相对离散一点。如采用一个较大固定值+一个较小的随机值，5小时+0到1800秒酱紫。
Redis 故障宕机也可能引起缓存雪奔。这就需要构造Redis高可用集群啦。

3.6 缓存击穿问题

「缓存击穿：」 指热点key在某个时间点过期的时候，而恰好在这个时间点对这个Key有大量的并发请求过来，从而大量的请求打到db。

缓存击穿看着有点像，其实它两区别是，缓存雪奔是指数据库压力过大甚至down机，缓存击穿只是大量并发请求到了DB数据库层面。可以认为击穿是缓存雪奔的一个子集吧。有些文章认为它俩区别，是区别在于击穿针对某一热点key缓存，雪奔则是很多key。

解决方案就有两种：

「1.使用互斥锁方案」。缓存失效时，不是立即去加载db数据，而是先使用某些带成功返回的原子操作命令，如(Redis的setnx）去操作，成功的时候，再去加载db数据库数据和设置缓存。否则就去重试获取缓存。
「2. “永不过期”」，是指没有设置过期时间，但是热点数据快要过期时，异步线程去更新和设置过期时间。

3.7、缓存热key问题

在Redis中，我们把访问频率高的key，称为热点key。如果某一热点key的请求到服务器主机时，由于请求量特别大，可能会导致主机资源不足，甚至宕机，从而影响正常的服务。

而热点Key是怎么产生的呢？主要原因有两个：

❝

用户消费的数据远大于生产的数据，如秒杀、热点新闻等读多写少的场景。

请求分片集中，超过单Redi服务器的性能，比如固定名称key，Hash落入同一台服务器，瞬间访问量极大，超过机器瓶颈，产生热点Key问题。

❞

那么在日常开发中，如何识别到热点key呢？

❝

凭经验判断哪些是热Key；

客户端统计上报；

服务代理层上报

❞

如何解决热key问题？

❝

Redis集群扩容：增加分片副本，均衡读流量；

对热key进行hash散列，比如将一个key备份为key1,key2……keyN，同样的数据N个备份，N个备份分布到不同分片，访问时可随机访问N个备份中的一个，进一步分担读流量；

使用二级缓存，即JVM本地缓存,减少Redis的读请求。

❞

4. Redis配置运维

4.1 使用长连接而不是短连接，并且合理配置客户端的连接池

如果使用短连接，每次都需要过 TCP 三次握手、四次挥手，会增加耗时。然而长连接的话，它建立一次连接，redis的命令就能一直使用，酱紫可以减少建立redis连接时间。
连接池可以实现在客户端建立多个连接并且不释放，需要使用连接的时候，不用每次都创建连接，节省了耗时。但是需要合理设置参数，长时间不操作 Redis时，也需及时释放连接资源。

4.2 只使用 db0

Redis-standalone架构禁止使用非db0.原因有两个

一个连接，Redis执行命令select 0和select 1切换，会损耗新能。
Redis Cluster 只支持 db0，要迁移的话，成本高

4.3 设置maxmemory + 恰当的淘汰策略。

为了防止内存积压膨胀。比如有些时候，业务量大起来了，redis的key被大量使用，内存直接不够了，运维小哥哥也忘记加大内存了。难道redis直接这样挂掉？所以需要根据实际业务，选好maxmemory-policy(最大内存淘汰策略)，设置好过期时间。一共有8种内存淘汰策略：

volatile-lru：当内存不足以容纳新写入数据时，从设置了过期时间的key中使用LRU（最近最少使用）算法进行淘汰；
allkeys-lru：当内存不足以容纳新写入数据时，从所有key中使用LRU（最近最少使用）算法进行淘汰。
volatile-lfu：4.0版本新增，当内存不足以容纳新写入数据时，在过期的key中，使用LFU算法进行删除key。
allkeys-lfu：4.0版本新增，当内存不足以容纳新写入数据时，从所有key中使用LFU算法进行淘汰；
volatile-random：当内存不足以容纳新写入数据时，从设置了过期时间的key中，随机淘汰数据；。
allkeys-random：当内存不足以容纳新写入数据时，从所有key中随机淘汰数据。
volatile-ttl：当内存不足以容纳新写入数据时，在设置了过期时间的key中，根据过期时间进行淘汰，越早过期的优先被淘汰；
noeviction：默认策略，当内存不足以容纳新写入数据时，新写入操作会报错。

4.4 开启 lazy-free 机制

Redis4.0+版本支持lazy-free机制，如果你的Redis还是有bigKey这种玩意存在，建议把lazy-free开启。当开启它后，Redis 如果删除一个 bigkey 时，释放内存的耗时操作，会放到后台线程去执行，减少对主线程的阻塞影响。
