unable to run mysql once it is downloaded

I have successfully reached the point where MySQL is downloaded but udo yum install -y mysql-server Loaded plugins: extras_suggestions, langpacks, priorities, update-motd 235 packages excluded due to repository priority protections Package 3:mariadb-server-10.2.38-1.amzn2.0.1.x86_64 already installed and latest version Nothing to do

when trying to run sudo service mysqld start && sudo service mysqld status I receive this error Failed to start mysqld.service: Unit not found.

Anyone else had this problem and resolved it ?
