redis安装好后，默认情况下登陆客户端和使用命令操作时不需要密码的。某些情况下，为了安全起见，我们可以设置在客户端连接后进行任何操作之前都要进行密码验证。
我这边是安装的window系统，修改redis.windows.conf配置文件
# Require clients to issue AUTH <PASSWORD> before processing any other # commands. This might be useful in environments in which you do not trust # others with access to the host running redis-server. # # This should stay commented out for backward compatibility and because most # people do not need auth (e.g. they run their own servers). # # Warning: since Redis is pretty fast an outside user can try up to # 150k passwords per second against a good box. This means that you should # use a very strong password otherwise it will be very easy to break. # # requirepass foobared requirepass hongda$123456
设置requirepass就可以
接下来要重启Redis服务
客户端授权方式
（1）登录时使用-a参数指定客户端密码，如下
（2）登录客户端后使用auth命令进行授权，如下
