关于Jedis连接redis出现问题

redis服务器系统：ubuntu  

ip 192.168.10.9

port 6379

两台电脑：一个作为专门的服务器，一个是开发环境

import redis.clients.jedis.Jedis;

public class Test {
	public static void main(String[] args) {
		Jedis jedis = new Jedis("192.168.10.9");
		jedis.auth("ldd");
		jedis.set("age", "1");
	 System.out.println(jedis.get("age"));
	}
}
