idea连接服务器端redis失败

Question

在使用idea连接服务器端的redis时失败！

服务器操作系统 CentOS8
redis版本 7.x.x

按照网上的教程，已经将

• protected-mode 设置成 no

• 将bind注释掉

• daemonize 设置成yes

• 设置了密码

• 服务器安全组也开放了6379端口

• 防火墙也打开了6379

使用idea连接时报错

密码写了否，试试

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

public class RedisConnectionExample {
    public static void main(String[] args) {
        // Set the Redis server host and port
        String redisHost = "your_redis_host";
        int redisPort = 6379;

        // Set the Redis server password (if any)
        String redisPassword = "your_redis_password";

        // Configure the connection pool
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        JedisPool jedisPool = new JedisPool(poolConfig, redisHost, redisPort, 0, redisPassword);

        // Create a new Jedis instance from the pool
        try (Jedis jedis = jedisPool.getResource()) {
            // Perform Redis operations
            jedis.set("key", "value");
            String result = jedis.get("key");
            System.out.println("Retrieved value: " + result);
        } catch (Exception e) {
            // Handle exception
            e.printStackTrace();
        } finally {
            // Close the Jedis pool
            jedisPool.close();
        }
    }
}
