DENIED Redis is running in protected mode报错解决办法

如下所示，程序连接redis报错，根据错误信息，redis运行在受保护模式，需要redis命令行下作设置:config set protected-mode no。

-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.

使用pycharm连接redis报错信息：

通过telnet命令检测redis端口6379

解决办法：

设置protected-mode no

再次通过telnet命令检测redis端口6379，没有出现访问异常。

再次运行python连接redis：

补充知识：

在linux/unix下使用telnet（telnet ip 端口号）连接主机时提示“Escape character is '^]'.”，这是什么意思？如何解决？

Escape character is '^]'.解决方法

“^”是Ctrl键的意思！

1、这个提示的意思是按Ctrl + ]会呼出telnet的命令行！

2、telnet命令行出来后，就可以执行telnet命令了；

3、退出telnet命令行的名为quit。

常用的telnet命令

close              关闭当前连接

logout            强制退出远程用户并关闭连接

display          显示当前操作的参数

mode            试图进入命令行方式或字符方式

open             连接到某一站点

quit               退出

telnetsend    发送特殊字符

set                设置当前操作的参数

unset            复位当前操作参数

status           打印状态信息

toggle          对操作参数进行开关转换

slc               改变特殊字符的状态

auth            打开/关闭确认功能z挂起

telnetenviron 更改环境变量?显示帮助信息

综上，Escape character is '^]'.只是一个提示，提示你使用Ctrl键+]键可以呼出telnet的命令行。
