Database Online Training Platform - Redis

 Introduction: remember a training process of the Redis online platform

First, enter the database online training platform , find the personal information column, and connect to the Redis database online, version V6.0.

Next, click to enter the Redis training environment, 

Enter the commands separately,

# View redis related command information

redis-cli --help

# View redis process information

ps -ef | grep redis

# Enter the redis window

redis-cli -p 6379 或 # 中文正常显示redis-cli -p 6379 --raw

# redis read-storage (key-value)

# 读取get listChargeCount # 存储set listChargeCount "['墨天轮','公众号','CSDN论坛']" 

We see that Chinese cannot be displayed normally, here we can pass the aforementioned:

# 中文正常显示redis-cli -p 6379 --raw

Ok, now, the basic key-value (Redis data structure: String-string type) is done, let's take a look (Redis data structure: Hash-hash type):

# 存储hset chargeCount dailyChargeCount "{'charge':1,'count':2}"# 读取hget chargeCount dailyChargeCount

Among them, the key is chargeCount, the field is dailyChargeCount, and the value is the object to be stored later. In fact, the value itself is a key-value pair structure, so we can regard key-field-value as key:field-value. It is more intuitive in the sense of caching and saves more space than the String type.

Here, we can mark in detail Redis's official value constraints on key and string types:

As for other data structure types based on Redis- actual project case-instant messaging , please refer to the translation point CSDN article:
