Where is mysql/administration command?

[Yoshinori Arai]

Hello,

I'm developping my site with httpd, php and mysql.
In my forerign distoro which is LFS, it is easy to setup the
development environment with XAMPP.

I have done system reconfigure to add httpd, mysql service to try to
setup same environment in GuixSD.

Mysql control commands is not in system profile but I can find these
commands in
/gnu/store/ni9waj5cyl94akwmzbrynfscy4k2igw7-mariadb-10.1.37/bin.

Is it correct way?
Why is not mysql commands in system profile?

Thank you.
