    When you add MySQL repository, it activate latest version by default. If you want older version, say 5.7, you need to activate it.

    To see available repository, run

    yum repolist all | grep mysql

    To disable MySQL 8 repository, run

    yum-config-manager --disable mysql80-community

    To enable MySQL 5.7 repository, run

    yum-config-manager --enable mysql57-community

    Now installing MySQL server will install MySQL 5.7 instead of latest version.
