这篇文章简单地介绍一下怎么在linux虚拟机上完成redis的安装及使用。目录1、安装redis2、使用redis3、启动/关闭redis启动redis启动方式一启动方式二启动方式三重启redis关闭redis查看redis状态4、在宿主机连接redis5、通过java连接redis创建maven项目添加jedis的依赖jedis的案例代码关闭保护模式重新运行代码1、安装redis首先访问Redis官网点击首页的【Get Started】然后点击Install Redis on Linux然后按照页面内容提示在Ubuntu上安装redis只需要在终端依次输入以下命令如果过程中没有错误提示则redis安装完成。sudo apt install lsb-release curl gpg curl -fsSL https://packages.redis.io/gpg | sudo gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg echo deb [signed-by/usr/share/keyrings/redis-archive-keyring.gpg] https://packages.redis.io/deb $(lsb_release -cs) main | sudo tee /etc/apt/sources.list.d/redis.list sudo apt-get update sudo apt-get install redis2、使用redis在终端输入redis-cli会进入到redis的命令行模式这时候就可以愉快地使用redis的各种命令了。输入exit退出redis-cli。3、启动/关闭redis启动redis启动方式一/etc/init.d/redis-server start启动方式二systemctl start redis-server启动方式三service redis-server start重启redisservice redis-server restart关闭redisservice redis-server stop查看redis状态service redis-server status4、在宿主机连接redis根据以上步骤安装启动redis后默认只能在虚拟机内访问redis如果在其他机器上访问需要修改配置文件。默认情况下redis的配置文件在/etc/redis/redis.conf打开这个文件注释掉下面的内容。bind 127.0.0.1 -::15、通过java连接redisredis官方推荐通过jedis来操作redisjedis是一个专门设计用于操作和快速使用redis的Java客户端。Jedis is a Java client for Redis designed for performance and ease of use.如图点击Client quikstart在点击展开的Java。如图官网已经给出了操作redis的方法创建maven项目在IntelliJ IDEA创建一个maven项目依次File - New - Project…然后在左侧选择Maven然后点击Next然后填写项目名和包名最后点击Finish就完成Maven项目的创建了。添加jedis的依赖在pom.xml中添加jedis客户端依赖dependency groupIdredis.clients/groupId artifactIdjedis/artifactId version4.3.1/version /dependency完整的pom.xml?xml version1.0 encodingUTF-8? project xmlnshttp://maven.apache.org/POM/4.0.0 xmlns:xsihttp://www.w3.org/2001/XMLSchema-instance xsi:schemaLocationhttp://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd modelVersion4.0.0/modelVersion groupIdorg.example/groupId artifactIdredis/artifactId version1.0-SNAPSHOT/version properties maven.compiler.source8/maven.compiler.source maven.compiler.target8/maven.compiler.target /properties dependencies dependency groupIdredis.clients/groupId artifactIdjedis/artifactId version4.3.1/version /dependency /dependencies /projectjedis的案例代码package com.example.redis; import org.junit.jupiter.api.Test; import org.springframework.boot.test.context.SpringBootTest; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; import java.util.HashMap; import java.util.Map; SpringBootTest class RedisTests { Test void contextLoads() { JedisPool pool new JedisPool(192.168.254.128, 6379); try (Jedis jedis pool.getResource()) { jedis.set(foo, bar); System.out.println(jedis.get(foo)); MapString, String hash new HashMap(); hash.put(name, John); hash.put(surname, Smith); hash.put(company, Redis); hash.put(age, 29); jedis.hset(user-session:123, hash); System.out.println(jedis.hgetAll(user-session:123)); } } }关闭保护模式运行上面测试类正常来说会看到绿条但是运行的时候发生了异常以下是控制台打印的异常信息redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled and no password is set for the default user. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command CONFIG SET protected-mode no from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to no, and then restarting the server. 3) If you started the server manually just for testing, restart it with the --protected-mode no option. 4) Set up an authentication password for the default user. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside. at redis.clients.jedis.Protocol.processError(Protocol.java:96) at
