问题描述
Mac中启动Mysql失败，异常信息如下
warning the usr/local/mysql/data directory is not owned by the mysql user
解决方案
此问题的原因是由于之前更新brew时统一更改了/usr/local的权限引起的，重新将/usr/local/mysql的权限授于mysql,操作如下
sudo chown -RL root:mysql /usr/local/mysql
sudo chown -RL mysql:mysql /usr/local/mysql/data
sudo /usr/local/mysql/support-files/mysql.server start
