The MariaDB configuration file

#

The MariaDB/MySQL tools read configuration files in the following order:

0. "/etc/mysql/my.cnf" symlinks to this file, reason why all the rest is read.

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 by the client and the server

use it for options that affect everything

show me your config that you're using to connect to db

I can't configure mysql. mysql should not be configured
I installed default-mysql-client and default-mysql-client-core. But still can't connect

I used to add skip-grant-tables in /etc/mysql/my.cnf. It is normal to skip password verification. But I removed skip-grant-tables and typing mysql -uroot -p on the kali system also skips the password.

very curious

i recommend to change port from 3366 to 3306 maybe that's the problem

For security reasons, update prot is 3366
Type mysql -uroot -p and press enter to skip the password
