The information you want can be found by running

mysql --help

or

mysqld --help --verbose

I tried this :

    mysql --help | grep Default -A 1

And the output:

                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash 
--
                      (Defaults to on; use --skip-line-numbers to disable.)
  -L, --skip-line-numbers 
--
                      (Defaults to on; use --skip-column-names to disable.)
  -N, --skip-column-names 
--
                      (Defaults to on; use --skip-reconnect to disable.)
  -s, --silent        Be more silent. Print results with a tab as separator,
--
  --default-auth=name Default authentication client-side plugin to use.
  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
--
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf

他们似乎都是不错的候选人：

/etc/my.cnf
/etc/mysql/my.cnf
/var/lib/mysql/my.cnf
...

在许多情况下，您可以简单地使用 ps 检查系统进程列表：

server ~ # ps ax | grep '[m]ysqld'

输出

10801 ?        Ssl    0:27 /usr/sbin/mysqld --defaults-file=/etc/mysql/my.cnf --basedir=/usr --datadir=/var/lib/mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock

或者

which mysqld
/usr/sbin/mysqld

然后

/usr/sbin/mysqld --verbose --help | grep -A 1 "Default options"

/etc/mysql/my.cnf ~/.my.cnf /usr/etc/my.cnf

从'/etc/mysql/my.cnf'的标题：

MariaDB programs look for option files in a set of
locations which depend on the deployment platform.
[...] For information about these locations, do:
'my_print_defaults --help' and see what is printed under
"Default options are read from the following files in the given order:"
