在配置文件redis.conf中，默认的bind 接口是127.0.0.1，也就是本地回环地址。这样的话，访问redis服务只能通过本机的客户端连接，而无法通过远程连接，
这样可以避免将redis服务暴露于危险的网络环境中，防止一些不安全的人随随便便通过远程
连接到redis服务。
如果bind选项为空的话，那会接受所有来自于可用网络接口的连接。
在使用redis的时候出现连接不成功；
在项目中导入jar包jedis-2.7.2.jar,编写测试类
@Test
public void testJedisSingle() throws Exception {
//创建一个jedis对象
Jedis jedis = new Jedis("192.168.64.129",6379);
jedis.set("test", "hello jedis");
String string = jedis.get("test");
System.out.println(string);
jedis.close();
}
根据redis.conf配置文件中bind的值的不同，出现不同的提示信息；但是不影响Linux系统中redis的正常使用;
当不存在bind时
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.
当bind 本机ip地址时
代码可以测试通过，但是Linux系统中出现问题
[root@root redis]# ./bin/redis-cli -c
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Could not connect to Redis at 127.0.0.1:6379: Connection refused
当bind 为默认的127.0.0.1时
代码测试不通过
redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect
Linux中操作正常
目前采用的方式，代码和Linux中的redis客户端都可以使用
1.在bind中配置多个IP地址,bind 192.168.64.129 127.0.0.1
2.将bind的值配置为bind 0.0.0.0
