我为包含MariaDB的OS X下载了XAMPP for OS X 5.6.14。 现在我想从数据库中更改datadir，但这不起作用。如果我启动mysql，来自XAMPP控件的灯是红色的，但服务“mysql”正在运行......
my.cnf看起来像这样：
[client]
socket = /Users/tobias/Documents/Webserver/mysql/mysql.sock
[mysqld]
socket = /Users/tobias/Documents/Webserver/mysql/mysql.sock
datadir = /Users/tobias/Documents/Webserver/mysql/
innodb_data_home_dir = /Users/tobias/Documents/Webserver/mysql/
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /Users/tobias/Documents/Webserver/mysql/
我将旧目录中的所有文件复制到新目录并尝试启动mysql。 之后，我收到了以下错误消息：

然后我运行mysql_upgrade，错误消失了。 我在日志中没有错误但数据库无法启动...服务正在运行，但Manager中的指示灯为红色。 phpmyadmin无法连接到db
有没有人有关于如何将mysql数据库目录移动到新目录的教程？
新文件夹的权限设置为mysql：mysql
谢谢！
