* Get the mariadb base packages (this is to avoid dependency conflicts)
yum -y install mariadb-libs mariadb-server
<!--* If mariadb gives conflicts with mysql, uninstall all mysql packages first (and then try the line above): yum -y erase 'mysql*'-->
* Try installing both hda-ctl and hda-platform. This should install a lot of dependencies with them
yum -y install hda-ctl hda-platform
