你好，我是猿java。
最近，因为换电脑，需要在本地安装 MySQL 的测试环境版本，电脑是 macOS M1芯片，因为中间折腾了一番，所以特意把安装的过程记录如下：
操作系统
MySQL源码下载
将文件下载到本地Mac的目录，如下：

# 查看，目录下新增 一个 mysql-8.0.30-macos12-arm64目录
weiki@WeikideMacBook-Pro custsoftware % ll

# 将解压目录移动到 /usr/local/mysql
weiki@WeikideMacBook-Pro custsoftware % mv mysql-8.0.30-macos12-arm64 /usr/local/mysq
# 增加 my-default.cnf 配置
weiki@WeikideMacBook-Pro cd /usr/local/mysql/
weiki@WeikideMacBook-Pro vim weiki@WeikideMacBook-Pro
[mysqld]
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
socket = /usr/local/mysql/data/mysql.sock
log-error = /usr/local/mysql/data/mysqld.log
[client]
socket=/usr/local/mysql/data/mysql.sock
为什么要放到 /usr/local/mysql
在 mysql/support-files/mysql.server 脚本里有如下描述

# If you install MySQL on some other places than /usr/local/mysql, then you
# have to do one of the following things for this script to work:
#
# - Run this script from within the MySQL installation directory
# - Create a /etc/my.cnf file with the following information:
# [mysqld]
# basedir=<path-to-mysql-installation-directory>
# - Add the above to any other configuration file (for example ~/.my.ini)
# and copy my_print_defaults to /usr/bin
# - Add the path to the mysql-installation-directory to the basedir variable
# below.
如果不把mysql安装到 /usr/local/mysql目录下，就需要做上述脚本描述的工作，因此，为了减少这些配置，所以把mysql安装到 /usr/local/mysql目录下
