How to access MariaDB from a Linux systemd service without password

Hello,

I'm running MariaDB 10.3 on my Debian 10 (Buster) with configurations in /root/.my.cnf

[mysql]

<some users and password>

user=meyer

password=<root-password>

user=root

password=<root-password>

[mysqladmin]

user=root

password=<root-password>

[mysqldump]

user=root

password=<root-password>

[mysqlcheck]

user=root

password=<root-password>

[client]

user=root

password=<root-password>

I'm able to connect to the database without password from terminal or bash script with "mysql -u root" but not with "mysql -u meyer". This is what I want. But if I start the bash script as a service I get the error "ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)" Do I have to configure something to enable passwordless root access from a service?

Thanks in advance Matthias
