前言

开发人员为了开发调试便利，经常需要在本地安装redis服务，本文分享一下如何使用brew在mac 本上进行redis服务的安装、调试以及安装过程中可能遇到的问题。

环境信息

MacOS12.3

M1芯片

Redis6.2

Brew 4.0.10

1. 查看可用版本

通过brew search命令查看可安装版本

2.安装指定版本的redis

通过brew install命令安装指定版本redis

注意如下输出信息，包括redis.conf配置信息和添加redis到PATH的方法

You have 5 outdated formulae installed.
You can upgrade them with brew upgrade
or list them with brew outdated.

==> Fetching redis@6.2
==> Downloading https://mirrors.aliyun.com/homebrew/homebrew-bottles/redis%406.2-6.2.14.arm64_monterey.bottle.tar.gz
######################################################################## 100.0%
==> Pouring redis@6.2-6.2.14.arm64_monterey.bottle.tar.gz
==> Caveats
redis@6.2 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.

If you need to have redis@6.2 first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/redis@6.2/bin:$PATH"' >> ~/.zshrc

To restart redis@6.2 after an upgrade:
brew services restart redis@6.2
Or, if you don't want/need a background service you can just run:
/opt/homebrew/opt/redis@6.2/bin/redis-server /opt/homebrew/etc/redis.conf
==> Summary
e??o  /opt/homebrew/Cellar/redis@6.2/6.2.14: 14 files, 2MB
==> Running `brew cleanup redis@6.2`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

3.添加redis到PATH

3.1 按照执行brew install命令后输出的提示信息执行如下命令将redis添加到PATH

echo 'export PATH="/opt/homebrew/opt/redis@6.2/bin:$PATH"' >> ~/.zshrc

3.2 执行命令要添加的redis环境信息生效:

source ~/.zshrc

否则可能报错:

zsh: command not found: redis-cli

4. 增加密码

此步骤可选，如果不需要密码可忽略增加密码这步

修改 /opt/homebrew/etc/redis.conf 增加密码

4.1 在文件中找到requirepass所在位置

4.2 去掉注释并将requirepass值替换为你为redis设置的密码

redis.conf的路径每台电脑可能不同，可以参照执行brew install命令后输出的信息查看

例如，我安装后redis.conf所在位置：

5. 启动服务

通过brew service start redis@6.2启动redis服务

如果你安装的是别的版本redis，将redis@6.2替换为指定版本即可

6. 使用redis服务

执行redis-cli -a redis密码 -p 端口号 连接redis服务

如果报如下错误，请试着执行source ~/.zshrc 命令后重试

7. 其他

• 重启服务

brew services restart redis@6.2

• 卸载服务

brew services stop redis@6.2 停止服务

brew uninstall redis@6.2 卸载服务
