远程连接 redis 时，报错 (error) DENIED Redis is running in protected mode because protected mode is enabled...

报错内容如下

(error) 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.

处理办法

方法一与方法二的区别在于，如果通过方法二通过命令行设置，那么每次程序启动都需要设置一遍。

方法一：修改配置文件

# 在 redis.conf 中找到 protected-mode 设置为 no
protected-mode no

方法二：通过命令行设置

# 在远端的服务器上面连接到 redis-cli 设置
127.0.0.1:6379> config set protected-mode "no"

最后搞定
