### 使用Homebrew安装Redis
1、没有安装Homebrew，首先安装npm国内的吧，快一些。
打开终端输入以下命令：
```
/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
```
2、使用Homebrew安装命令
```
brew install redis
```
执行上述命令后出现以下，则成功安装：
```
==> Homebrew has enabled anonymous aggregate formula and cask analytics.
Read the analytics documentation (and how to opt-out) here:
https://docs.brew.sh/Analytics
No analytics have been recorded yet (nor will be during this `brew` run).

To have launchd start redis now and restart at login:
brew services start redis
Or, if you don't want/need a background service you can just run:
redis-server /usr/local/etc/redis.conf

3、 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
4、启动redis服务
```
//方式一：使用brew帮助我们启动软件
brew services start redis
//方式二
redis-server /usr/local/etc/redis.conf
```
```
//执行以下命令
redis-server
```
*****
5、查看redis服务进程
我们可以通过下面命令查看redis是否正在运行
```
ps axu | grep redis
```
6、redis-cli连接redis服务
redis默认端口号**6379**，默认**auth**为空，输入以下命令即可连接
```
redis-cli -h 127.0.0.1 -p 6379
```
7、启动 redis 客户端，打开终端并输入命令**redis-cli**。该命令会连接本地的 redis 服务。
```
$redis-cli
redis 127.0.0.1:6379>
redis 127.0.0.1:6379> PING
PONG
```
在以上实例中我们连接到本地的 redis 服务并执行**PING**命令，该命令用于检测 redis 服务是否启动。
8、关闭redis服务
* 正确停止Redis的方式应该是向Redis发送SHUTDOWN命令
```
redis-cli shutdown
```
* 强行终止redis
```
sudo pkill redis-server
```
9、redis.conf 配置文件详解
redis默认是前台启动，如果我们想以守护进程的方式运行（后台运行），可以在**redis.conf**中将`daemonize no`,修改成`yes`即可。
