Redis allows remote connections

　　After the default installation and startup of redis, it can only connect locally, but cannot connect remotely. The reason is that the redis security policy defaults to local access, so remote access needs to be

The # in front of bind 127.0.0.1 in the configuration file redis.cof is commented out,

Sometimes just commenting out these is not enough, because the new version adds protected mode, specific prompt information

    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.

 

Although it can be turned off by setting the protected mode to no, it is recommended to set a permission password for security:

Find the line # requirepass foobared, remove the # and change foobared to your password.
