From old times there was mysql.conf than come additional my.cnf, both files with same content. So if there my.cnf - just make renamed copy there. If single file was deleted - you can create new and put there just two strings:
user=da_admin
passwd=MYSQLPASS
mysql-password you can find in /usr/local/directadmin/scripts/setup.txt
or you can change pass to NEW: https://docs.directadmin.com/other-hosting-services/mariadb-mysql/troubleshooting.html
my.cnf has three strings:
[client]
user=da_admin
passwd=MYSQLPASS
