redis.clients.jedis.exceptions.JedisDataException: 
DENIED Redis is running in protected mode because protected mode is enabled, no bind address wasspecified, 
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 loopbackinterface 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.

在将redis集成在项目中时,如果是新安装在linux服务器的服务端,第一次使用往往会报JedisDataException:DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified异常。其实使用RedisTemplate连接远程Redis服务器的时候,Redis默认状态下是一守护状态下安装运行的,所以如果不是本地连接,就会报这个错误,而错误的提醒也很明显。redis的保护模式已经激活。没有绑定特定的连接ip地址,没有授权密码,
在这种情况下,连接只能是本地连接。
而想要从外部连接,则可以采取以下几种方式:
1):redis服务器运行时,在本地连接,并且运行命令:CONFIG SET protected-mode no.但是如果你要这样做,
你要确保Redis不要公开在互联网上,使用命令CONFIG REWRITE来使文件来永久的改变
2):第二种方式,你可以编辑Redis的配置文件,将protected mode选项的值改成no,并重新启动redis服务
3):如果你启动Redis只是为了测试使用,你可以重启Redis服务,加上--protected-mode no参数
4):设置绑定特定的ip地址或者给一个身份密码
以上的选项,使用其中一种就可以使用了

配置文件:redis.conf

# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1

#protected-mode yes

# requirepass foobared
