MySQL: 改变Homebrew安装MySQL/MariaDB的数据库文件目录

1. brew install mariadb

2. mysql_install_db --verbose --user=$USER --basedir=/usr/local/Cellar/mariadb/10.1.8 --datadir="/Volumes/KG's Big YO/Documents/mysql_data" --tmpdir=/tmp

3. 修改mysql.server脚本文件（/usr/local/Cellar/mariadb/10.1.8/bin)中的datadir="/Volumes/KG's Big YO/Documents/mysql_data"

最后启动MySQL:

mysql.server start

Done.
