MariaDB upgrade 'blocked' by MySQL dependencies

Post by cmkl » 2022/01/08 02:27:27

Hi there.

I am running CentOS 7 with MySQL Community Server v 5.7.

I would like to move to MariaDB 10.6 but I cannot because MySQL just won't 'let go'.

I cannot just yum install mariadb etc because the MariaDB server package conflicts with all the MySQL community packages.

I tried to remove mysql-community-* (listed out all the package names just in case) but Yum wants also to remove a lot of stuff that I definitely need. Like Postfix, Fail2ban, OpenDMARC etc etc. Yum considers these dependencies of the mysql-community packages.

I am scared to remove all the MySQL-community dependencies and re-install along with the MariaDB packages because (a) if I also lose the configs it will be huge chore to reinstate and (b) if some of them don't go back with MariaDB that will be very bad.

The dependency list looks like this:

There is a yum swap command that might work but I think that if this were me, I would use the yum shell command. The shell lets you stack up commands into one transaction and have it do them all in one go. In your case when you try to remove the mysql packages, yum will then expand the selection to include all those things that depend on what they provide and will try to remove those too. If you use yum shell then you can tell it to remove those and then install the mariadb versions and have it do both at the same time. A very simplified example of what you'd do is

yum shell
> remove mysql-libs
> install mariadb-libs
> run

You can use 'ts' to test and show you what it will do before you say 'run'.

Your case will be more complicated as you will need to have a full list of the packages that you want to install though you can at least use wildcards to remove mysql*
