Я установил maria db в моем centos 7, но теперь после удаления maridb с:

yum remove MariaDB-server MariaDB-client 

когда я устанавливаю mysql-devel или mysql или mysql-сервер, он всегда устанавливает maridb. Как я могу вернуться к mysql?
Я также удалил репозиторий mariadb из списка репозиториев по адресу: /etc/yum.repos.d
На:

yum install mysql mysql-server mysql-devel

Журнал ошибок в cmd:

[root@ONS88 ~]# yum install mysql mysql-server mysql-devel
