默認安裝啟動redis後，只能本地連接，無法遠程連接上，原因是redis安全策略默認本機訪問，所以遠程訪問的話需要將

配置文件redis.cof 中的 bind 127.0.0.1 前面的#註釋掉，

    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.
