一. 登录阿里云服务器并安装redis
Download, extract and compile Redis with:$ wget https://download.redis.io/releases/redis-6.2.1.tar.gz$ tar xzf redis-6.2.1.tar.gz$ cd redis-6.2.1$ make The binaries that are now compiled are available in the src directory. Run Redis with: $ src/redis-server 或者执行，nohup src/redis-server & 来后台运行
You can interact with Redis using the built-in client:$ src/redis-cliredis> set foo barOKredis> get foo"bar" 二. 在安全组规则里面添加访问规则，开启6379端口。
三. 连接redis的时候，出现
redis.exceptions.ResponseError: DENIED Redis is running in protected mode because protected mode is enabled 错误
这时，设置protected-mode no即可
最后用 Another Redis DeskTop Manager输入阿里云主机和端口，即可连接redis数据库。
