redis 故障处理：持续更新

redis 内存快满：

突发性：

1.1 当突发的时候，先进行扩容redis 内存：
CONFIG SET maxmemory 6G
1.2 通过monter 获取当前redis  请求，发送给开发，让开发进行处理一下

缓慢性：

进行扫描一下redis 过期kay 进行删除冗余垃圾kay,命令如下：
SCAN cursor [MATCH pattern] [COUNT count]
# 我这边已经编写好二进制程序了如果可以需要自行下载：

redis连接数异常

开发语言：lua
redis 架构：redis cluster
# 进入redis 里面使用monitor 查看最近的操作：

发现了一大堆关于redis 锁的数据，这边就不继续展示了

根据监控发现一直集群种了2个节点一直挂，分别是192.168.0.3:6301和192.168.0.1:6302
查看对应kay对应的节点

# 发现关于redis 这个xixixixi 的kay全部都在192.168.0.3:6301和192.168.0.1:6302种
所以会导致redis 连接数一直在2个机器上进行发送信息，
# 解决办法：
通知开发进行修改代码，把kay设置成动态的
