在哪里可以找到包含所有参数的 mysql 配置文件？

Question

Where can I find mysql config file with all parameters? I found some config files in

/etc/mysql/

directory but there isnt any file with all parameters !

Actually I want my machine's mysql server to be remotely accessed. So I was finding " bind-address " parameter in the file but there is not one file with all parameters: These are the files I found in this directory:

./conf.d 
./conf.d/mysql.cnf 
./conf.d/mysqldump.cnf 
./debian-start 
./debian.cnf 
./mariadb.cnf 
./mariadb.conf.d 
./mariadb.conf.d/50-client.cnf 
./mariadb.conf.d/50-mysql-clients.cnf 
./mariadb.conf.d/50-mysqld_safe.cnf 
./mariadb.conf.d/50-server.cnf 
./my.cnf.fallback 
./my.cnf

I read some articles saying that my.cnf is the mysql config file but there is no bind-address or anything this is the output of my.cnf file.

# The MariaDB configuration file
#
# The MariaDB/MySQL tools read configuration files in the following order:
# 1. "/etc/mysql/mariadb.cnf" (this file) to set global defaults,
# 2. "/etc/mysql/conf.d/*.cnf" to set global options.
# 3. "/etc/mysql/mariadb.conf.d/*.cnf" to set MariaDB-only options.
# 4. "~/.my.cnf" to set user-specific options.
#
# If the same option is defined multiple times, the last one will apply.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

#
# This group is read both both by the client and the server
# use it for options that affect everything
#
[client-server]

# Import all .cnf files from configuration directory
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mariadb.conf.d/

Answer 1

Do you want the settings you put in my.cnf or some other file?

Or do you want all 500 or so settings, including the defaults, such as in SHOW VARIABLES ?

Answer 2

Try tables like:

use performance_schema; select * from.global_variables where variable_name in ('bind address','port');

Answer 3

You can see the search path for my.cnf file by using the following command: sudo mysqld --help --verbose | grep cnf

The normal search path is: /etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf /.my.cnf

And, if not present then create a /etc/my.cnf file.
