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

Posted 2022-04-25 luffy5459

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。

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.

复现问题，通过telnet命令检测redis端口6379

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。
