# 异常信息 #

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.  
大概意思就是redis处在保护模式,需要接触保护模式或者是设置密码可以继续使用

--------------------

**这种情况只有在进行外部服务器连接时才会出现**,redis在3.2.\*版本之后添加了这个功能,网上网上有不少解决方法[这是解决办法][Link 1]  
但是经过我的尝试还是会出现上述问题的bug

## 解决方法 ##

1、修改redis服务器的配置文件  
    vi redis.conf    
    
    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  
    127.0.0.1:6379> config set daemonize "no"  
    OK  
    
    修改redis的保护模式为no，不启用  
    127.0.0.1:6379> config set protected-mode "no"  
    OK  
    设置redis密码
    127.0.0.1:6379> config set requirepass admin
    OK

**完成上述配置之后再次尝试连接**

192.168.100.161:6379> get lol
    (error) NOAUTH Authentication required.
    192.168.100.161:6379> auth admin
    OK
    192.168.100.161:6379> d
    (error) ERR unknown command 'd'
    192.168.100.161:6379> set key lol
    OK
    192.168.100.161:6379> get lol
    (nil)

连接之后报错改变,需要输入密码,输入设置好的密码之后就可以正常使用了.

## 使用java连接同样如此,在配置项里添加密码即可 ##

#redis配置
    spring:
      redis:
        host: 192.168.100.161
        port: 6379
        password: admin
