redis

远程连接redis时发现怎么都现连接不上而且一直报错

Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect  

测试代码：

import redis.clients.jedis.Jedis;
/**
 * Created by harry on 2016/10/6.
 */
public class Test {
    public static void main(String[] args) {
        Jedis jedis = new Jedis("121.42.152.75",6379);
        System.out.println("Connection to server sucessfully");
        //check whether server is running or not
        System.out.println("Server is running: "+jedis.ping());
    }
}

后来发现是配置的问题，默认情况下，只允许本机访问redis

vim /etc/redis/redis.conf

注释bind,将bind 127.0.0.1注释成如下形式

bind 127.0.0.1

然后重启服务器，
重启redis

sudo service redis-server restart

大功告成！

Connection to server sucessfully
Server is running: PONG
