Redis版本:3.2.0 Jedis版本:2.8.1

下面是我连接到redis的java代码:

public class TestRedis {
public static void main(String[] args) {
    String host = args[0];
    int port = Integer.parseInt(args[1]);
    try (Jedis jedis = new Jedis(host, port)) {
        System.out.println("Connected to jedis " + jedis.ping());
    } catch(Exception e){
        e.printStackTrace();
    }
}

}

我在安装了redis的机器上运行此程序.这台机器的IP地址是192.168.1.57

如果我提供host ="localhost"和port ="6379"作为参数,则成功建立与redis的连接.

但是,如果我在参数中给出host ="192.168.1.57"和port ="6379",我最终得到以下异常:
