Redis容許遠程鏈接

　　默認安裝啓動redis後，只能本地鏈接，沒法遠程鏈接上，緣由是redis安全策略默認本機訪問，因此遠程訪問的話須要將

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

有時僅僅註釋掉這些還不行，由於新版本增長了保護模式，具體提示信息

    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.

 

雖然能夠將保護模式設爲no來關閉，但爲了安全仍是推薦設權限密碼：

找到這一行# requirepass foobared，將#去掉並把foobared改爲你的密碼便可。
