Jedis连接远程服务的redis一些问题

首先是打开远程redis，我使用的是虚拟机centOS 6.4

然后下载jedis的jar包

连接：https://mvnrepository.com/artifact/redis.clients/jedis

测试代码为：

import redis.clients.jedis.Jedis;

public class MyJedis {
    public static void main(String[] args) {
        Jedis jedis = new         Jedis("192.168.184.129",6379,10000);
        //Jedis jedis = new Jedis("localhost");
        System.out.println("连接成功");
        jedis.set("ylh", "ylh");
        System.out.println(jedis.get("ylh"));
    }
}

出现了如下错误：Caused by: java.net.SocketTimeoutException: connect timed out

原因是cenOS安装默认打开防火墙

解决方案：

1. 在windows上ping Linux虚拟机的ip，测试连接

 2. 检查Linux下的防火墙是否关闭

       用/ect/init.d/iptables status 查看防火墙状态

       用/etc/init.d/iptables stop  关闭防火墙

 

之后执行代码出现如下错误

Exception in thread "main" redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

解决方案：

vi redis.conf    
1、修改redis服务器的配置文件  

注释以下绑定的主机地址  
# bind 127.0.0.1  
  
   
2、修改redis服务器的参数配置  
  
修改redis的守护进程为no ，不启用  
daemonize no

  
修改redis的保护模式为no，不启用  
protected-mode no
