brew install redis
mac:
1、安装redis
brew install redis
Warning: Treating redis as a formula. For the cask, use homebrew/cask/redis

Error: redis 5.0.8 is already installed
To upgrade to 6.0.8, run `brew upgrade redis`.
输入brew upgrade redis
耐心等待，马上就会更新到6.0.8
之前没有更新brew，所以下载的是5.0.8版本
2、启动redis
brew services start redis 或 redis-server /usr/local/etc/redis.conf 可以省
==> Successfully started `redis` (label: homebrew.mxcl.redis)
3、停止redis
brew services stop redis
Stopping `redis`... (might take a while)
==> Successfully stopped `redis` (label: homebrew.mxcl.redis)
4、重启redis
brew services restart redis
重启直接报错：Error: undefined method `named' for #<OptionParser:0x00007fc65f26a3b8> /usr/local/Homebrew/Library/T
解决：
brew update -v
更新一下brew就可以了。应该是新了mac，然后就得更新一下brew
==> Successfully started `redis` (label: homebrew.mxcl.redis)
5、测试redis
redis-cli ping
==>PONG
6、测试一下redis-cli
% redis-cli
127.0.0.1:6379> set foo bar
OK
127.0.0.1:6379> get foo
"bar"
127.0.0.1:6379>
7、放二个免费的开源工具
https://github.com/qishibo/AnotherRedisDesktopManager
新建连接，就可以连上本机的，然后就可以在左侧看到所有的key，右侧就是值。
