Redis容许远程链接

　　默认安装启动redis后，只能本地链接，没法远程链接上，缘由是redis安全策略默认本机访问，因此远程访问的话须要将

配置文件redis.cof 中的 bind 127.0.0.1 前面的#注释掉，

有时仅仅注释掉这些还不行，由于新版本增长了保护模式，具体提示信息

    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.

 

虽然能够将保护模式设为no来关闭，但为了安全仍是推荐设权限密码：

找到这一行# requirepass foobared，将#去掉并把foobared改为你的密码便可。
