在开发过程中，需要本地进行安装Redis进行测试，记录了下MacOS环境下安装Redis，以及设置密码。

Brew 安装

$ brew install redis

启动服务

# 启动服务
brew services start redis
# 关闭服务
brew services stop redis
# 重启服务
brew services restart redis

# 查看 redis 服务进程
ps axu | grep redis

# 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

设置密码

方式一：设置临时密码

重启服务后密码会失效

$ config set requirepass 123456

方式二：设置永久密码

需要修改配置 redis.conf

# 查看 brew 安装 redis 的配置文件地址
$ brew list redis

/opt/homebrew/Cellar/redis/7.0.11/homebrew.redis.service

# 进入目录
$ cd /opt/homebrew/Cellar/redis/7.0.11

# 查看 redis 配置文件位置
$ cat  homebrew.mxcl.redis.plist

# 编辑 /opt/homebrew/etc/redis.conf
$ vim /opt/homebrew/etc/redis.conf

# 查找 「#requirepass foobared」 进行修改
requirepass 123456

# 重启 redis 服务
$ brew services restart redis

查询密码：

# 查询密码
$ config get requirepass

# 验证密码
127.0.0.1:6379> auth 123456
