此文章的前置条件是 “Mac系统已安装过Homebrew”，如果未安装，可访问 “Mac 安装 homebrew 详细教程” 一文，详细介绍Homebrew的用法。利用 “Homebrew” 对 “Redis” 进行安装管理，那是一个方便啊。
利用 homebrew 安装 Redis
Homebrew是一款 macOS 平台下缺失的软件包管理工具，拥有安装、卸载、更新、查看、搜索等很多实用的功能。简单到什么程度呢，仅仅通过一条指令，就可以实现包管理，而不用你关心各种依赖和文件路径的情况，十分方便快捷。
Homebrew会将将这些工具统统安装到了 /usr/local/Cellar 目录中，并在 /usr/local/bin 中创建软链接。
PS：没安装 “Homebrew” 的同学，可以访问 “Mac 安装 homebrew 详细教程” 一文参考。

==> Caveats
To restart redis after an upgrade:
brew services restart redis
Or, if you don't want/need a background service you can just run:
/usr/local/opt/redis/bin/redis-server /usr/local/etc/redis.conf

查看安装及配置文件位置
- Homebrew安装的软件会默认在
/usr/local/Cellar/路径下 - redis的配置文件
redis.conf存放在/usr/local/etc路径下
安装指定按本的 Redis 服务
- 上面我们默认安装的事最新版本的 “Redis” ，除此之外，还可以安装指定版本的的 “Redis” ，只需在安装命令后面增加对应的版本号即可。
brew install redis@6.2
# 指定安装的版本号配置 Redis 环境变量
说到配置环境变量这一步，不得不吐槽一句、完全没必要。
当我们使用 "homebrew" 安装好 "Redis" 的时候，会帮我们配置好环境变量(也就是软连接 到 /usr/local/bin 目录)，所以我们可以在终端的任意目录下运行命令 "redis-server" 命令来启动 "redis"
❯ which redis-server
/usr/local/bin/redis-server
❯ where redis-server
/usr/local/bin/redis-server
❯ where redis*
/usr/local/bin/redis-benchmark
/usr/local/bin/redis-check-aof
/usr/local/bin/redis-check-rdb
/usr/local/bin/redis-cli
/usr/local/bin/redis-sentinel
/usr/local/bin/redis-server
启动 redis 的两种启动方式、重启与关闭查看本地运行的服务列表
启动方式①：
通过 brew services 来启动(后台启动) ；强烈推荐
brew services start redis
# 通过 brew service 命令启动 redis
启动方式②：
也可以通过上文提到的 redis-server 启动；PS：需要注意的是，这样的启动方式，在关闭窗口后，redis 服务就停止了，不推荐！
redis-server
# redis 默认的启动方式，但是在关闭终端窗口后，redis 服务就停止了，所以不推荐。
重启
brew services restart redis
# 通过 brew service 命令重启 redis 服务
关闭
brew services stop redis
# 通过 brew service 命令关闭 redis 服务
查看本地 redis 是否正常运行连接本地的Redis
- 查询 redis 服务
brew services list | grep redis
# brew services list 是查询当前 brew 启动的所有的服务
连接本地的Redis
redis 默认端口号6379，默认auth(密码)为空，输入以下命令即可连接
redis-cli 是 redis 安装的时候自带的命令行客户端，使用如下命令连接 redis
redis-cli -h 127.0.0.1 -p 6379
# -h : host - ip地址
# -p : port - 端口号
# -a : auth - 密码；存在密码的情况下使用，当前默认状态没有密码，所以省略了。
连接成功后，使用 ping 命令与 redis服务端 做心跳测试，服务端正常会返回 pong 。
