ping不通6379端口，redis修改配置启动未生效

-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.

可以从这几个方面去排查。

大概分析就是关闭保护模式，开放端口，设置bind ip规则及连接密码。

解决方法:

打开redis的注册路径，修改配置文件 redis.conf，注意以下三个位置。

1. 修改bind后面的ip

bind 0.0.0.0

2.修改yes为no

protected-mode no

3.设置连接密码

最后保存，启动redis。

发现还是报错，而且和上面错误信息一样，证明刚才的修改没有起到作用。

启动时连带上配置文件的路径，再用客户端尝试连接，连接成功。
