Hey all,

I just got around to trying out CentOS 7. And for some reason when I
attempt to install mysql-server, instead I’m offered mariadb? I’m using epel and remi as my repos.

Is this ok [y/d/N]:

I don’t know what you think, but this is just weird to me. Why on earth would CentOS 7 be trying to get me to install a database that I don’t really want instead of MySQL? Nothing against mariadb. It’s just that I
haven’t tried it yet, and don’t have a real interest to.

Thanks Tim

  • Hi,

    This is a similar move with replacing OpenOffice (back then also under the Oracle umbrella) with LibreOFfice. Replace product owned by evil corporation with the true open source alternative (which happens to be developed by the original devs of MySQL!); this may not be RH’s main reason, but it’s how I see it.

    For one I totally support this move and I was a bit afraid RHEL7 wouldn’t be released in time to incorporate this change.

    You should use MariaDB without fear, it should be the same thing and replaces MySQL gracefully.

  • There are concerns in the wider open source community about Oracle’s long-term plans for MySQL. I also imagine there is some concern from RedHat that Oracle is trying to move in to RedHat’s space with Oracle Linux.

    Questions about non-CentOS repos should probably be directed to lists for those repos; CentOS has no official authority over EPEL (I am not familiar with remi).

    If MariaDB is coming from EPEL, as suggested by your yum output, then CentOS is not trying to get you to do anything. But I believe that MariaDB is also in core CentOS. Perhaps RH does not have an alias for mysql-server but EPEL does?

    MariaDB should be a drop-in replacement for MySQL. If you have concerns about Oracle and MySQL you should seriously consider trying MariaDB. You may decide against it, of course, but at least you’ll have made a technical decision instead of a knee-jerk one. (I do still find links that conflate MySQL and MariaDB, which is unfortunate.)

  • The short answer is because RH chose to use mariadb instead of MySQL in EL7. As others have said, this is similar to the openoffice->libreoffice switch. There should be very minimal (if any at all) difference in functionality.

  • Mariadb replaces mysql in RHEL-7 (and also Fedora 19), so it also replaces mysql in CentOS-7.

    yum install mariadb-server should be used to get the default mariadb server from the distro.
