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-cli
redis> set foo bar
OK
redis> 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。
