# Redis 學習記錄

1. SpringBoot 使用redis並實現cache機制: https://www.tpisoftware.com/tpu/articleDetails/

聖哥的安裝紀錄

//redis 密碼
/etc/redis/redis.conf

127.0.0.1:6379


//停用

sudo /etc/init.d/redis-server stop


//啟用

sudo /etc/init.d/redis-server start


//驗證
ubuntu@ip-172-31-16-219:~/kafka_2.11-0.11.0.0$ redis-cli 
127.0.0.1:6379> AUTH PASSWORD

## 常用操作

### list key
keys *
keys match_live*

### get key
get key
hget key
lget key...

get遇到錯誤訊息: WRONGTYPE Operation against a key holding the wrong kind of value
---
物件類型與使用的get類型不一致。 先確認key 類型: type key

### delete
模糊刪除:
redis-cli KEYS "match_live:text*" | xargs redis-cli DEL

模糊刪除 - auth:
redis-cli -a '1q2w3e4r..A' KEYS "match_live:inde*" | xargs redis-cli -a '1q2w3e4r..A' DEL

### rename key
rename [key] [newkey]

### Redis中存储value中文显示问题

解决方法：
启动redis-cli时，在其后面加上–raw即可，汉字即可显示正常。
[root@localhost redis]# ./bin/redis-cli --raw
127.0.0.1:6379> get China
中国

## 遠端連線
$ redis-cli -h host -p port -a password

### version
在服務器：
redis-server -v

在redis-cli：
info

## 報錯修正

### connect to redis failed, MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk

## 集群

##### 集群查keys:

redis-cli -c --cluster call 127.0.0.1:6378 keys \match_live:te*

addr 換成集群其中一個節點addr
