org.springframework.data.redis.RedisSystemException: Redis exception; nested exception is io.lettuce.core.RedisException: io.lettuce.core.RedisConnectionException: 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.

這個錯誤沒愁死我, 開始我以為阿里雲簡訊服務改了規定, 畢竟上次測試成功, 今天卻失敗了, 而我的電腦也沒關機過

所以我充值5000條簡訊

後來還是報錯, 我就知道白花花的銀子真的白花了

檢視ifconfig

紅框裡的資訊都查不道, 原來是虛擬機器出了問題

關機重啟虛擬機器:

一定要關機再重啟

開啟虛擬機器的終端檢視IP, 這次可以正常顯示了

啟動Redis【其實這步也錯了】

redis啟動之後還是報錯, 提示找不到虛擬機器這個IP地址

那麼就檢視防火牆是不是又自動開啟了?

systemctl status firewalld.service

果然重啟虛擬機器後防火牆自動開啟了

關閉虛擬機器防火牆

systemctl status firewalld.servie

關閉後在檢視防火牆狀態

在Redis啟動和防火牆關閉的情況下還是報錯, 並且Redis的配置沒有問題, 簡訊充足o(╥﹏╥)o

那麼問題在哪兒呢? 一定是啟動方式出了問題

Redis正確啟動方式

[root@localhost bin]# ./redis-server redis.conf

我的redis.conf和redis-server都在bin目錄下【根據個人配置情況操作】

手動收到了驗證碼

成功了
