【NOIP2017提高A組模擬9.17】貓

redis3.2版本後新增protected-mode配置,預設是yes,即開啟。設定外部網路連線redis服務,設定方式如下:

1、關閉protected-mode模式,此時外部網路可以直接訪問

2、開啟protected-mode保護模式,需配置bind ip或者設定訪問密碼

如果開啟保護模式 ,而未配置bind 會報一下錯誤

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.
