blocking mariadb

Post by john2018 » 2018/09/21 23:33:03

I'm just going through the process of removing mariaDB to make a Centos-7 system compatible
with Centos-6 and read that mariaDB features may keep trying to install?

If that's so is there any way I can prevent that happening?

My specific requirement at the moment is a LAMP installation so thats mainly
apache mysql php phpmyadmin etc.
But I'm also concerned about any other features that may be messed up.

I've installed the public mysql repo and am about to try installing mysql
(tommorow - I've already yumdownload-ered them as the target is not online
- I do quite a bit of that)
I'm hoping I've removed everything mariadb related.
It looks like I'll need to re-install postfix at least judging by a message
trevor posted (I got distracted just as the list came onscreen and I hit Y) ... damn...

PS - thanks for the tip about "yum shell" elsewhere Trevor - I've made a note of that one.

Why bother? Mariadb is a fork of mysql, made by one of the original authors when Oracle bought Sun (who in turn had bought mysql). Almost all linux distros now supply mariadb not mysql by default. It uses the same SQL syntax, the same API, runs the same queries since it came from the same place.
The future appears to be RHEL or Debian. I think I'm going Debian.

It isn't the same as the system I need the machine to be compatible with
so has to go for security and support reasons alone.

The fact that it insinuates itself all over the system makes applications
unpredictable and sadly is just one more nail in the centos coffin here.

It is just one more too big a change for enterprise level support.
So the question is how do I prevent it messing up my systems
if I try to update after putting mysql back? Or will that not happen?
I'm just trying to find out.

We ship mariadb and everything that needs a "mysql"-type library is built against it. We do not support mysql packages and you use them at your own risk. If you think you have found bugs in mariadb then report them on bugzilla.redhat.com and get them fixed. As far as stability goes, you are the first person I have ever seen reporting problems with mariadb.

If you really need mysql, then install it. As far as I remember, there is a 'mariadb-libs' that has to be replaced with it's counterpart from the mysql repo.
Yet, I would prefer using MariaDB instead of mySQL.

Of course we need it. It's what we use.
The only reason to fork is to do something different so mariaDB is either
not compatible now or will not be compatible in the near future.
That is not acceptable in an enterprise environment.
red hat have done a great job of dismantling the sole reason
to choose them/centos.

Perhaps you should actually try MariaDB first. You may be surprised how easily it would fit in your environment.

The only reason to fork is to do something different so mariaDB is either
One advantage of the fork is that it is free of a certain vendor that's not perceived as being particularly opensource friendly. See also OpenOffice/LibreOffice, Jenkins/Hudson and probably others over the years.
