The editor will share with you a detailed introduction of the redis command. I hope you will gain a lot after reading this article. Let's discuss it together.

Below by the Redis tutorial column to introduce the redis command, hope to help friends in need!

Redis command:

Redis key (key)

The Redis key command is used to manage the keys of redis.

The basic syntax of the Redis command is as follows:

Redis 127.0.0.1 6379 > COMMAND KEY_NAME

Redis string (String)

Commands related to the Redis string data type are used to manage redis string values. The basic syntax is as follows:

Redis 127.0.0.1 6379 > COMMAND KEY_NAME

Redis hash (Hash)

Redis hash is a mapping table for field and value of type string, and hash is particularly suitable for storing objects.

Redis list (List)

The Redis list is a simple list of strings sorted in the order in which they are inserted. You can add a header (left) or tail (right) of the element guide list.

Redis Collection (Set)

The Set of Redis is an unordered collection of type string. Collection members are unique, which means that there can be no duplicate data in the collection

Redis ordered set (sorted set)

Redis ordered collections, like collections, are collections of elements of type string, and duplicate members are not allowed.

Redis HyperLogLog

Redis added the HyperLogLog structure in version 2.8.9.

Redis publish and subscribe

Redis publish subscription (pub/sub) is a mode of message communication: the sender (pub) sends the message and the subscriber (sub) receives the message.

Redis transaction

Redis transactions can execute more than one command at a time with two important guarantees:

A transaction is a separate isolation operation: all commands in the transaction are serialized and executed sequentially. In the course of execution, the transaction will not be interrupted by command requests sent by other clients.

A transaction is an atomic operation: either all or none of the commands in the transaction are executed.

Redis script

The Redis script uses the Lua interpreter to execute the script. Reids 2.6 supports the Lua environment through built-in support. The common command to execute a script is EVAL.

Redis connection

The Redis connection command is mainly used to connect to the redis service.

Redis server

Redis server commands are mainly used to manage redis services.

Redis Ping command

The Redis Ping command uses the client to send a PING to the Redis server, which returns a PONG if the server is functioning properly.
