----Basics of Redis Database

The Redis database is also known as the data structure database because the storage is based on key-value mode.

Where value can be a string (String), a hash (map), a list , a collection (set), and an ordered set (Zset).

Under the Redis installation directory, there is a file redis.confthat stores the basic configuration information for Redis.

By modifying This file, start again with the following command:

Redis-server Redis.conf-path

The configuration information is applied

Use the command:

Redis-cli

will open the Redis client

In this client, the configuration is obtained/modified by the following command:

Config get keyconfig set key value

It is worth noting that the set value in the client is temporary , and the value of set will not be preserved the next time the Redis server restarts.

Some basic operations (add and revise) are as follows:

Delete any key value:

Del Key1

string :

Set Key1 ' python '----del key1----Get Key1

Hash :

Hmset key1 F1 v1 F2 v2----hdel key1 f1----hget Key1 F1

List :

Lpush (rpush) K1 ' python '----lpop K1

Collection :

Sadd key1 ' python '----srem key1 ' python '----smembers key1

ordered Collection (Themember values are unique and are sorted by default in order of score from small to large ):

Zadd key1 1 ' python ' 2 ' cpp '----zrem key1 ' python '----zrange Z 0 10
