Jedis access to redis denied

CentOS7.0 installed redis4.0.10, successfully and connected successfully with RedisDesktopManager on windows.

CentOS Firewall is off:

redis.conf:

the java program is as follows:

public static void main(String[] args) {
    Jedis jedis = new Jedis("127.0.0.1",6379);
    System.out.println(jedis.get("name"));
}

the error is as follows:

Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect
    at redis.clients.jedis.Connection.connect(Connection.java:207)
    at redis.clients.jedis.BinaryClient.connect(BinaryClient.java:93)

    at cn.chao.JedisTest.main(JedisTest.java:15)
Caused by: java.net.ConnectException: Connection refused: connect
    at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method)

you need to make sure that your service is actually running

    ps -ef | grep redis
    netstat -antp | grep 6379

your java program runs on the same machine as redis?
