Testing MySql V.8 under RHEL 8
MySql totally ignores /etc/my.cnf instance parameters and always startup with default mysqld process.
Even I renamed my.cnf, mysqld can still be started up with the default mysqld.
I have searched the whole filesystem and no other location contains my.cnf file except /etc/my.cnf.
I was trying to setup multi-instance of mysql for example [mysqld.dev] and use systemctl start mysqld@dev to startup.
Can anyone provide some hints for me?
