requirepass redis
protected-mode no

systemctl start redis.service
systemctl enable redis.service


redis-cli -h 192.168.184.12 -p 6379
auth redis

下载jedis-3.1.0.jar

import redis.clients.jedis.Jedis;

public class TEST {

    public static void main(String[] args) {
        Jedis j = new Jedis("192.168.184.12",6379);

        j.set("key1", "lijiahong");
        String s = j.get("key1");
        System.out.println(s);
    }
