Welcome to the Redis Getting Started tutorial! This guide will help you understand the basics of Redis and how to get started with it.

简介

Redis 是一个开源的、高性能的键值对存储系统。它可以用作数据库、缓存和消息中间件。Redis 的主要特点包括高性能、持久化、丰富的数据结构支持等。

安装 Redis

To install Redis, you can visit the official Redis website here and download the appropriate version for your operating system.

配置 Redis

After installing Redis, you need to configure it by editing the redis.conf file. Here are some basic configuration options:

  • bind 127.0.0.1: This option limits the Redis server to only accept connections from the local machine.
  • port 6379: This option sets the port on which Redis will listen for connections.
  • daemonize yes: This option makes Redis run as a background process.

连接 Redis

Once Redis is configured and running, you can connect to it using a Redis client. For example, you can use the redis-cli command-line tool to connect to the Redis server:

redis-cli -h 127.0.0.1 -p 6379

基本操作

Here are some basic Redis operations:

  • SET key value: This command sets the value of a key.
  • GET key: This command retrieves the value of a key.
  • DEL key: This command deletes a key.

For example:

127.0.0.1:6379> SET mykey "Hello, Redis!"
OK
127.0.0.1:6379> GET mykey
"Hello, Redis!"
127.0.0.1:6379> DEL mykey
OK

数据结构

Redis supports various data structures, including strings, hashes, lists, sets, and sorted sets. Here's a brief overview of each:

  • Strings: Strings are the simplest data type in Redis. They can store any kind of text data.
  • Hashes: Hashes are similar to dictionaries in Python. They can store key-value pairs.
  • Lists: Lists are ordered collections of strings. They can be used to store sequences of elements.
  • Sets: Sets are unordered collections of unique strings. They can be used to store sets of elements.
  • Sorted Sets: Sorted sets are similar to sets, but they also store scores with each element. This allows you to retrieve elements in sorted order.
