Hi,

After adding the Repo
nano /etc/yum.repos.d/MariaDB10.repo

I just did and upgrade.

yum -y upgrade maria*

I didn’t uninstall the previous installation and in 2 mins it was Up and running with new MariaDB 10

Thanks,

Regarding the dependencies, removing via rpm command without blowing up dependencies:

# rpm -e --nodeps mariadb mariadb-libs mariadb-server

Then yum install the packages. MariaDB-Shared replaces mariadb-libs which is what postfix, etc needs. You will then find the packages are satisfied:

# yum deplist postfix

and you will see the MariaDB-Shared is a accepted provider.

Thanks everyone for your tips and advice. I was able to recovered my previously existing databases by adding the datadir parameter to the my.cnf file. I then restarted the database and all was good. Interestingly enough I later had to remove this references from the my.cnf because of startup errors but the database does not lose its relationships with the databases. This I can not explain.

@Kirt,

You can import your database and run mysql_upgrade command to upgrade the database structures with new engine..

Upgraded MariaDB5.5 to 10.0 following these steps including removal of MariaDB. I then used yum to install mariadb10.0. This went without error. I then started the MariaDB service and it showed the correct version.

However, the previously existing database was not found. How do I re-attach the old database to the new database engine so I can run the upgrade procedure against it? The old data files are still available.
