我试图在 Mac (High Sierra) 上运行通过 HomeBrew 安装的 MySQL，但我总是遇到这些权限和 PID 文件问题。我尝试了在网上找到的数百种可能的解决方案，但无法解决这些问题：

Haline:/ Haline$ mysql.server start
Starting MySQL
./usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 144: /usr/local/var/mysql/Haline.local.err: Permission denied
/usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 144: /usr/local/var/mysql/Haline.local.err: Permission denied
/usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 199: /usr/local/var/mysql/Haline.local.err: Permission denied
/usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 144: /usr/local/var/mysql/Haline.local.err: Permission denied
 ERROR! The server quit without updating PID file (/usr/local/var/mysql/Haline.local.pid).

有人可以帮助我吗？
