Java链接Redis出现DENIED Redis is running in protected mode because protected mode is enabled

Exception in thread "main" 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.

    这里就是当你改正这个连接超时的错误的时候，我们就应该接着改下一个错误了。第一个错误肯定就是这个bind属性造成的，紧接着就会出现这个问题。

    第二个问题是因为远程连接redis redis自我保护 拒绝访问；有两种解决方案可以选择：   

    一、直接去掉自我保护功能（不推荐）

    进入你的Reids.conf配置文件，然后vi进行修改：

    将这个protected-mode yes改为protected-mode no

    编辑后 重启redis服务，然后运行 ，结果出来了

    二、加密码

    查看redis是否添加密码

    

    默认情况下 requirepass 参数是空的，这就意味着你无需通过密码验证就可以连接到 redis 服务。

    你可以通过以下命令来修改该参数：

    

    这样以后就设置了密码，以后我们再redis-cli之后，要：

    

    通过auth给出密码才能链接，对应的就是我们远程链接的java代码中，添加：

    

    这样就可以避免错误了哈哈哈
