/etc/percona-server.conf.d/mysqld.cnf is empty

Hi.

I installed the server Percona Server as follows:

https://www.percona.com/doc/percona-server/LATEST/installation/yum_repo.html

percona-release setup ps80

yum install percona-server-server

I started the service so:

systemctl enable mysqld.service

systemctl start mysqld.service

systemctl status mysql.service - service is active

However configuration file along the way /etc/percona-server.conf.d/mysqld.cnf - is empty

OS CentOS 7.

What did I lose sight of?
