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
3, 附录
用一个外部客户端 RedisStudio 来访问查看 Redis 的数据
