@Test
        public void testJedis(){
            //创建jedis对象、(xx:6379)
            String host="xxx.100";
            Jedis jedis = new Jedis(host,6379);
            System.out.println(jedis.ping());
            //调用jedis对象的方法（与redis的命令基本差不多）
            jedis.set("key1","jedis-test11");
            System.out.println(jedis.get("key1"));
            //关闭jedis
            if(jedis !=null){
                jedis.close();
            }
        }

当你执行以上代码出现问题的时候  
看看  
./redis-cli -h xxx -p 6379  
能不能成功运行

[root@localhost bin]# netstat -apn|grep 6379
    tcp        0      0 xxx:6379    0.0.0.0:*               LISTEN      5139/./redis-server 
    [root@localhost bin]# ./redis-cli -h xxx -p 6379 
    xxx:6379> set day24 eat
    OK
    xx:6379> quit
    [root@localhost bin]#

很明显redis客户端成功连接，这样java来连接redis客户端，就成功了  
这样就可以测试成功
