Redis 外网访问设置

Redis 外部访问设置

1、错误原因

Redis搭建好后一般都是使用编程语言进行连接调用，默认Redis的设置是不允许外界访问的，外界telnet请求Redis服务器的时候会有如下提示：

-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.

这说明目前处在保护模式上，查看Redis的注释可以了解，连接Redis只能通过本地（127.0.0.1）来连接，而不能使用网络IP（192.168.1.x）来连接，如果需要请修改配置文件redis.conf

 

2、解决方案

进入Redis目录打开Redis.conf配置文件

 

1>注释掉bind
#bind 127.0.0.1
2>默认不是守护进程方式运行，这里可以修改
daemonize no
3>禁用保护模式
protected-mode no

 

启动Redis并指明配置文件

redis-server ../redis.conf

 

OK，通过外网telnet一下Redis服务器看看是否通了，在编程语言中连接Redis也就可以了

用一个外部客户端RedisStudio来访问查看Redis的数据
