我试图按照https://www.mkyong.com/mysql/where-does-mysql-stored-the-data-in-my-harddisk/上的说明操作。我在示例中找到了my.cnf中的etc/mysql文件，但令我惊讶的是它并不包含任何基本设置，只有以下内容：

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
我还希望使用user =，datadir =等行。是不是MySQL设置不正确？
答案 0 :(得分：0)
在Marc B发表评论之后，我做了一些搜索，发现在Askubuntu上回答了同样的问题：https://askubuntu.com/questions/699903/why-etc-mysql-my-cnf-is-empty。
重申一下，includedir行表示可以在列出的目录中找到其他配置文件（在这种情况下为.cnf）。
